Distinctions, Forms, and Science

“A universe comes into being when a space is severed or taken apart… by tracing the way we [make such distinctions] we begin to reconstruct … the basic forms underlying linguistic, mathematical, physical, and biological science.” — G. Spencer Brown Laws of Form (1979)

Swirls, Whorls, and Tendrils

Although I am a physicist by day—or, perhaps, because I am a physicist (and thus want the left part of my brain to rest when I'm with my camera)—I have rarely come upon a subject that seamlessly combines my love of physics and passion for photography. Until now that is. Maybe it is my penchant for abstraction that led to this subject, and the connection to physics is more of an afterthought. Or maybe my physics “eye” unconsciously led me to take on this aesthetically surreal but very “real” physical subject, in hopes of stirring my conscious attention (and relentless equation scribbling). Whatever the case, my recent focus on “ink drop in water abstracts” has consumed both sides of my brain, and is—even as I write this blog entry—unlikely to release either side any time soon. A small—exploratory—gallery of images is here.

Ink diffusion, in turns out, is anything but simple; either photographically or mathematically (for an example of the latter, see, for example, this paper on ink diffusion in Chinese ink paintings). On the photographic side, many photographers—amateur, pro, unknown, famous, living and long forgotten—have doubtless focused their lens’ on “ink & water” countless times, perhaps stretching all the way back to Fox Talbot. I have no illusions of having discovered a new “frontier” (as Bruce Barnbaum did with his magnificent shots of Slit Canyon). But even a familiar subject can sometimes offer unexpected surprises. My own humble addition to photography's collective oeuvre of subject matter is more akin to Hilla and Bernd Becher's typology of watertowers and other industrial structures. Only in my case, it is a typology of the dispersive structures of a single ink drop in water.

The technique is straightforward, but requires a bit of practice and patience. A small 3”-by-3” glass vase is filled with about ¾” of water (less than that, or more, yields a set of slightly “different” patterns from those appearing here) and placed on a light table (which provides the only source of light). A macro lens (in this case, a 100mm lens capable of 1:1 magnification) is mounted on a camera (Canon's 30D DSLR), and is positioned so that the lens is pointing vertically downward on the surface of the water. A small eyedropper is filled with India ink, is carefully centered between three and six inches above the water (as with water depth, a greater or lesser height yields a slightly different set of patterns), and a single drop—this is the "hard" part that requires a bit of patience—is slowly released.

As the ink strikes the water, about a third of its volume quickly spreads radially on the surface. The remaining blob sinks to the bottom. Some of it bounces back up, and a slow process of diffusion, dispersion, and rotation begins. The resulting 3D patterns are captured (and compressed into two dimensions via the lens) as they unfold, and are processed and displayed as digital negatives. A single drop’s effective "unfolding lifetime" varies between 1-1/2 and 2-1/2 minutes. It is not a real lifetime, of course, since the ink continues to diffuse until it is thoroughly mixed with the water, but denotes a period after which most of the "interesting" patterns—the swirls, whorls, and tendrils—have all but dissipated, and no new internal structures appear. The images in this portfolio show the structure of the radial spread of a single drop of ink in water as it appears at a single time (to within ~ 1/60th sec) near the tail end of its unfolding lifetime.

Each ephemeral form is unique, surreal, and exquisitely beautiful. Since these are lifesize macros, many of the fine details are literally invisible to the naked eye. The macro lens reveals what looks like "organic" life-forms, that develop as though some hidden “rule” (or genetic code) is guiding their evolution. In truth, the myriad shapes and forms are a complicated confluence of multiple simultaneous forces at work: diffusion, dispersion, interplay of relative viscosities of the water and ink, a transfer of momentum as the ink drop bounces upward after hitting the bottom of the vase, gravity, random drifts and impurities in the water, and thermal convection rolls due to the heat generated by the bulbs in the light table.

Tellingly, even as each delicate form is “perfect” onto itself, what starts the whole process going, and what is most responsible for the diversity of patterns, is imperfection. It is because the ink drops are not perfect spheres, because they assume a variety of randomly distorted oblong shapes as they fall, and because they have unpredictable and shifting densities of ink inside of them, that each sequence is a unique creation that unfolds just once, then vanishes forever.

"All is process.
That is to say, there is ‘no thing’ in the universe.

Things, objects, entities, are abstractions
of what is relatively constant from a process of
movement and transformation.
They are like the shapes that
children like to see in clouds."
— DAVID BOHM, Physicist (1917-1992)

Postscript/FYI. Apart from the fact that it nicely describes the subject of my new series, the title for this portfolio - "Swirls, Whorls, and Tendrils" - derives, in part, from the first (and, so far as I can remember, the only time) I have ever seen the word "whorl" used seriously in print anywhere. I remember seeing this term in a paper co-authored by one of my mathematical physics professors in graduate school (N.L. Balazs), back in the late 70s; though on a topic that doesn't have anything to do (at least explicitly;-) with ink drops in water: Quantum Maps.

Matted & Framed Prints for Sale!

Although I have not written about it much on my blog, I have for the past nine months or so been a part of a new art cooperative in northern Virginia called the Lorton Arts Foundation (LAF). In particular, I was one of 14 inaugural juried members of LAF's Workhouse Photography Society (WPS). This group contains many fine and distinguished artists, with a wide diversity of backgrounds and styles. All are exceptionally talented photographers, and I am very honored to have had an opportunity to hang my work alongside theirs. Regrettably, however, because of other projects and time commitments, I have had to resign my WPS membership, effective at the end of June.

While I have other venues and options open to me to hang - and hopefully sell - my work, some friends recommended I try probing my blog readers' interest in acquiring some ready-to-hang fine-art photos. So, here is a first such offering.

The prints for sale are all (slightly warmly duotoned) digital prints - using Epson's archival pigment-based ink. I use Epson's 2400 printer and print on Epson's acid-free Ultrasmooth Fine-Art Paper (to assure colorfastness and longevity). All prints are roughly 17 inches long on the longest side, and are displayed using either an off-white (print 1 and 2) or light-gray (prints 3 and 4) matte-board fit into an 18" - by - 24" black metal frame. The prints are signed on the lower right of each print, sans "edition number" as I do not follow that practice (perhaps I'll post a blog entry on my thought process here).

The price of each matted/framed print is $240.00 + $15.95 for packing and shipping. Since this is an "experiment" (to see if there is sufficient on-line interest), payment is via check, to be made out to "Ilachinski Studios, Inc." All matted/framed prints are offered on a first-come-first-served basis, and will be shipped within five working days of my receiving a check (if impossible for whatever reason, I will inform the buyer via email of any delay). I will not cash any check until the buyer has confirmed receiving the print and has indicated complete satisfaction. If that is not the case, I ask that the matted/framed print please be returned (though here at the prospective buyer's expense; keeping the original shipping container will obviously save on return cost here), and I will destroy the uncashed check upon arrival (or send it back to the buyer, if he or she so chooses).

If interest is strong, I will periodically offer a few of my prints in this way, if only because it provides me an opportunity to expand a bit on my blog on how the images came to be. As is true of most photographers, each of my photos has a "story" to tell, beyond that of what they depict as merely physical objects.

So, without further adu, here are the first four prints I am offering for on-line sale (if interested in purchasing one or more of these prints, please email me at ilachinski.studios@gmail.com):

1. Luminous Boundary

I have discussed this image recently in the context of the unconscious influence other artrists have on our own work. In this case, the image is an "unconscious" homage to a similar work by British photographer Fay Godwin. Although I was not thinking of Godwin, nor any other photographer (so far as I am aware), during the time I captured this image a few yeas ago at tropical park in Coral Gables, Florida, her characteristically soulful approach to her subject matter has certainly impressed itself on me in the years of studying her work. This is one of my favorite images from the last five years or so, and seems to always grab people's attention when they pass it hanging on a wall.

2. Tonal Rhythms

This image was captured on the same day as "Luminous Boundary." It is another of my favorites because it captures (and shows) "light" as much as form. Though it is hard to see in a web-sized picture, the print has a wonderfully subtle "glow," as if shining with an inner light; and has a beautiful organic texture that would look nice on (some otherwise drab painted) wall

3. Micro Worlds

This is an image from my "Micro Worlds" portfolio, which was published in Lenswork last year (Issue #76, May/June 2008; 16 images appeared in the print edition, 75 images + audio interview on the Extended DVD edition -(I also have a self-published book that contains many more images from the same series). It is a macro of a small thumbnail-sized portion of an acrylic candle holder. Apart from its aesthetic appeal, I like this image because it serves as powerful reminder that beauty truly lives everywhere, even in the seemingly "unlikeliest" of places. This print is matted on a light-gray matte board.

4. Mystic Flame


This is one of my favorite abstract images from last year. It is from my Mystic Flame portfolio, about which I wrote a blog entry. (I also have a self-published book that contains many more images.) While it may look like smoke, it is actually a reverse/negative image of a flame; and a relatively small one at that. The actual flame-size was between two and three inches. This print, like the Micro Worlds above, is matted on a light-gray matte board.

The Gentle Madness Known as Abstract Photography

The "abstract" image to the left is what is "left" of a framed print called "Fractal Dignity" that was part of a one-man show in Coral Gables I had in Dec 2007. I had it (along with other prints remaining from the exhibit) sent from storage this past week to my mom's home in Sea Cliff, NY (Long Island), so she could hang it in my dad's old art studio on the second floor. Unfortunately, the shipment arrived in deplorable condition. Most of the glass is completely fractured, with many of the prints scratched beyond repair. Other frames that appear unaffected at first glance, contain broken shards and smaller pieces of glass trapped between an otherwise solid piece of glass and the matte underneath, hinting at frayed and broken edges of glass along the inner walls of the surrounding metal frame. The frames themselves have also been badly scratched, as though the package delivery service used them for an impromtu baseball game (or two, or three).

  

Needless to say, my mom and I were shocked when we opened the first of four (similarly configured boxes) when my son and I arrived for a short weekend trip for him to see his "Baba." The outer condition of the boxes betrayed a bit of what we soon found inside - the boxes were smashed, dented and had major tears and rips along the edges - but we were not prepared for the extent or severity of damage. It took about two hours to fully document and inventory the damage, picture by picture; with the bottom line being that fully none of the 24 frames are in "sellable" condition, and will have to be reframed. Moreover, at least half of the prints will have to be redone as well. As for me, I quickly went through the Kubler-Rossian stages of grief over a "death of a loved one" (the "loved ones" being my prints): denial, anger, bargaining, depression, and acceptance (did I mention anger?!? ;-). I knew I finally had my emotions under (some semblance of) control when - though still miffed; good grief, I'm still miffed, as a write this a few days after the fact! - I found myself picking up my camera not to document the damage, but to actually start composing what appeared to me a rather nice little "abstract" (as you see documented at the top of this entry). Photographers - especially those whose "eye" is attracted to abstract forms - are strange creatures indeed. My 10yo son stared incredulously, dropped jawed, as his dad - who moments before was apoplectic with primal rage directed at the universe in general and the UPS delivery service in particular - suddenly quieted down, got "that look" in his eye, starting circling one of the open boxes with all of its exposed shards of glass and mangled metal, and started clicking away as if nothing at all was the matter. A lesson about how accidents can serve as catalysts for transforming representational art into abstraction? Perhaps; or it may just be another everyday example of the gentle madness known as abstract photography :-)

Postscript. Though the outcome of my claim is at this time unknown, the shipment was insured. Hopefully, that should defray at least some of the cost (though not the time) of reprinting and reframing these images.

Traversing an N-Dimensional Aesthetic Space

I've been musing lately about a problem that has stubbornly resisted my attempts at solving it for quite some time; indeed, I sometimes wonder if I've made any headway at all in all the years I've spent reflecting on it. Perhaps I should pay heed to the title of my own blog - namely tao - and plumb a bit of tao's timeless wisdom. To wit, maybe I ought to treat my problem not as a "thing" that needs solving, but as a transient stepping-stone on a timeless path toward gradual self-enlightenment.

"What is beauty?" I [S Nachmanovitch] asked him that night. He [Gregory Bateson] said, "Seeing the pattern which connects." (quoted from Old Men Ought to be Explorers, by S. Nachmanovitch)

My "problem" is to find the "optimal feature space" in which to describe the aesthetic sensibilities of particular artists; that is, essentially, to find an objective language (or, least as objective a language as possible) to describe the subjective propensities of, and differences between, individual painters, musicians, or photographers. We all "know" the difference between, say, Mozart's music and that of Beethoven; or the difference between a painting by Matisse and another by Picasso. Sometimes the differences, as in these "obvious" cases, are striking. In other cases, the differences may not be so clear cut: if one was, a priori, unfamilar with the works of Minor White and Brett Weston, for example, some of their respective abstracts may appear - superficially at least - as aesthetically indistinguishable.

Somehow, perhaps in the way that Malcolm Gladwell calls "thin slicing" in his book Blink, we all make quick, largely unconscious, assessments about makes one work different from, or similar to, another. We can sometimes analyze - after the fact - why we made the decision of similarity or difference that we made. But (as Gladwell also points out in his book), we are not always able to articulate the precise feature-space decomposition we used to make our rapid-fire decision (because our subconscious thought-process does not always percolate up to the conscious level); nor can we really be sure that whatever feature-space decomposition we are able to articulate is an accurate reflection of what our unconscious information processing. Of course, often our thin-slicing attempts are also simply wrong.

The larger question, even if only as a thought experiment, remains. Let's start small, and not yet all-encompassing - a bit later I will generalize the question from photography to all forms of creative expression - and confine our analysis to photography alone, as an exemplar of a broader class of "art" and its associated larger class of aesthetic possibilities. We ask: what is the optimal set of "features" (to be defined shortly) of "photographs" such that - in the N-dimensional abstract aesthetic space defined by these features as (roughly) orthogonal axes - two conditions are simultaneously satisfied: (1) the differences among photographs is maximized (with respect to sets of photographs produced by individual photographers), and (2) the differences between photographs produced by the same photographer (i.e., between any two images within a given photographer's own oeuvre) are minimized? In a sense, I want to perform a "simple" exercise of mathematical pattern recognition, but without any (or little) initial sense of what space I'm performing it in, or even what I'm setting out to "recognize."

What do I mean by features? Well, any reasonably well-defined "parameter" that can be used to describe a photograph (which may, implicitly, involve both its physical attributes, as a print, and nonphysical attributes, such as subject matter or other contextual primitives). Of course, many different features exist (indeed, the set of possibilities is enormous); but not all features are as important in describing a work as others. More precisely, different sets of features will be better, or worse, at simultaneously identifying the works that are produced by a given photographer and distinguishing among bodies of works produced by different photographers.

Thought Experiment #1. Schematically, we can imagine a 3-dimensional space (in general, the dimension D can be very large) consisting of the features f1, f2 and f3. As a thought experiment, imagine we have the collected works of three of photographers (A, B, and C; that we "code" using the colors red, blue, and green). We classify each photograph, of each photographer, according to where in the feature space in lives. It does not matter whether the "points" in this space are cleanly defined or not; the only thing that matters for this thought experiment is the fact that every work by each of the three photographers is classified according to the values of the three features we have used to define this particular "aesthetic space" F = {f1, f2, f3}. As a concrete example, the three features might be: f1=average hue, f2=degree of local constrast, and f3=number of triangular shapes. And, indeed, as we might expect of such a loose (random almost) set of parameters, we would not be surprised to learn (if we actually went to the trouble of performing this experiment) that these features do little to distinguish among our three photographers. Our plot of their respective oeuvres might look something like this...

But now, suppose we are a bit more clever than this. Suppose, after carefully studying the works of these three photographers, we discover a new set of features - {f1', f2', and f3'} - such that, in this new aesthetic space, F', the same body of work now appears considerably more tightly clustered:


Here we see - by direct visual inspection - an "obvious" distinction among the photographers A, B, and C. Moreover, we see that work produced by a given artist is itself clustered around a relatively small volume of the full aesthetic space. "A" is obviously confined to one region, separate from (in this case) the volume of space occupied by "B," and both are distinct from the volume occupied by "C."

My point here is not that a feature space within which such a decomposition is possible exists - it may, or may not, for a given set of artists; but only that it suggests an interesting and deep question about what such a set of features - that simulataneously minimizes the differences among a given photographer's works and maximizes the distinction among the works of different photographers - might actually look like! I suspect it may not be like anything we would intuitively expect; if our intuition is anything like what we learn in the standard art and graphics design books. I doubt very much whether the "core features" would include such standard-issue measures as "contrast" and "tone" (though they may very well these). I wonder, too, at just how far separated the artist's "oeuvre clusters" can be made to be, while the spread of each artist's own cluster of works is simultaneously minimized.

One can play other thought games too, of course, For example, having defined some aesthetic space, and having plotted a given artist's current oeuvre - say, what the artist has produced during the last five years of work - we can trace how the artist evolves, using the first plot as a reference. Does the work remain more or less in the same "cloud" of points, so that the artist does not stray too far from his (possible innate?) aesthetic? Or does the cloud slowly dissipate, and reform in another region of the same aesthetic space? Or does the cloud diffuse outward to fill most, or all, of the "old" aesthetic space, thus suggesting that a new feature space - some F'' - exists, and in which the same artist's evolving oeuvre again assumes a cloud-like form?

Thought Experiment #2. Here is an even deeper question; and, truth be told, the real object of my rambling quest. Suppose we have managed to find a special "core aesthetic" space that does precisely what our thought experiment imagines. That is, imagine we have an aesthetic space defined by a special set features (whose relevance, for the moment, is confined solely to photography) that both maximizes the difference between different photographers, and - simultaneously - minimizes the differences between individual photographs of a given photographer. Suppose, further, that we carve out of that space a special set of photographs (and, by association, a special set of photographers) which maximize - for lack of an objectively better-defined word - photographic beauty. Now, imagine we do exactly the same thing (i.e., play the thought experiment as described above) for all of the different kinds of creative endeavors that exist: music, sculpture, literature, mathematics, physics, ... The analog of (generic) "beauty" in art or photography might be - in the case of mathematics, for example - "truth" (as in the truth of theorems); in physics, "beauty" may be aligned with "physical laws" (the "truths" of nature), and so on. What is the underlying meta-pattern that connects the patterns?


Here is my question (and I'll stop at this point): might there be a "universal aesthetic meta-map" that transforms the set of features of one aesthetic space (that describes art, say) to another set of features that describe a different aesthetic space (mathematics, say) but which leaves the measure of "beauty" that is appropriate for each kind of space invariant?

"We do not want merely to see beauty...we want something else which can hardly be put into words; to be united with the beauty we see, to pass into it, to receive it into ourselves, to bathe in it, to become part of it." - C. S. Lewis

"Beautiful" art or music, "physical laws" in physics, and "theorems" in math may be - in a truly fundamental sense - indistinguishable, but only if the analog of "beauty" is correctly defined , and interpreted, in each respective space. Indeed, I suspect that if only we were clever enough creatures to be able to simultaneously apprehend and reflect upon vast multidimensional features spaces, it would only be a matter of "shifting our perceptual / aesthetic axes" (so to speak) for us to be able to transform our endeavors from one creative space into another. Imagine being able to "prove a mathematical theorem" by working on the problem as though it were an art project (and the object of which - in the art space - is to produce a "beautiful work of art"). But whatever space we happen to find ourselves in at a given moment, the object of our quest (and the ultimate arbiter of our creative progress) remains indefagitably the same: truth.

Postscript #1. The way I presented my thought experiment, a (God like) external agent is needed to view the universe of artists and their work to construct (and plot the creative progress in) a D-dimensional aesthetic space. In fact, one can argue that each artist (indeed, each living being) is doing precisely that, ceaselessly, tirelessly, throughout its existence. We are all seeking to be as distinct as possible from all other living beings, even as - at the same time - we desire to be be as integrated into our local cultural / creative fabric as well. It is this insoluble yin-yang tension that drives all self-motivated dynamics; and perhaps all creativity. This fundamental idea of the universe consisting of simultaneous and seemingly antithetical tendencies of integration and distinction (or assertiveness), at all levels of a multidimensional hierarchy, was introduced by author / philosopher Arthur Koestler in a book called Janus. He called all such creatures that strive to do this holons.

Postscript #2. The idea that there is a core universality that underlies all forms of art - all life - is certainly not born in this humble blog entry. In fact, much of my thinking on the subject derives from, and has been shaped by, a magnificent four volume work called Nature of Order by architect / visionary Christopher Alexander (about whom I've written before on my blog).

Postscript #3. A similar idea to the one presented above as thought experiment #1 (but in the context of cosmology) - and developed more completely on a semi-rigorous mathematical level - was proposed a few years ago by physicists Julian Barbour and Lee Smolin. They called it extremal variety. Barbour has published another article on this subject in the Harvard Review of Philosophy.

The Click of the Shutter Button...and A Deep Mystery

Physics is replete with "revolutions" in world-view that emerged after someone was brilliant enough - and brave enough - to question the foundations of "common wisdom." Witness Copernicus and his assertion that the Earth was not the center of the universe; Newton and his realization that the same force that binds us, as physical beings, to this planet is the same one that keeps the planets in their orbits; James Clerk Maxwell and his curiosity about the relationship between electricity and magnetism; Einstein and his stubbornly persistent analysis of the deep meaning of simultaneity; and Louis de'Broglie (along with a handful of others, including Einstein) puzzling over the difference between particles and waves. The list goes on and on, of course. In each case, a seemingly mundane - but sincere - questioning of an "obvious" fact (as Tommy Lee Jones says to the Will Smith character in the movie Men in Black, as he tries recruiting Smith's character to join MIB: "Everybody knew the Earth was flat...") led to a radical conceptual reordering of how we think of the universe, and our role in it.

While I do not propose any such radical reconceptions of our world in this humble little blog entry, I am going to suggest that the "creative act of photography" affords us an opportunity to ask a disarmingly trivial question (that may indeed alter how we perceive and interact with our environment, and ourselves). I will preface the question by first positing that one of the deepest mysteries confronting science today (apart from questions pertaining to the standard model of physics, string theories, or loop quantum gravity) is the nature and origin of consciousness. Consciousness is something we all, presumably, possess; yet is something about which - apart from knowing we possess it, and guessing that our experience of it is "pretty much the same" as that of any other humanly conscious creature - we have little or no real understanding.

Three of the more cogent (and often widely disagreeing) discussions of consciousness are (1) Consciousness Explained (by Daniel Dennet), (2) The Conscious Mind (by David Chalmers), and (3) I am a Strange Loop (by Douglas Hofstadter). None of these, of course, "explains" consciousness; but all are great at stimulating further discussion.

My particular interest, at least for purposes of this blog entry, is that aspect of consciousness that has to do with intentionality; i.e., the (apparently) willful decision to "act" (such as when we decide to "press the shutter" of a camera). Before I ask that question, however, consider this "simple" experience: I am holding a ball in my hand, which, at some point in time, for whatever reason, I decide to throw up in the air a few inches, and catch again. A trivial everyday act. Yet an utter mystery, as far as both fundamental physics and our understanding of consciousness is concerned. Just as there is no "physics" (of which I am aware), no equations or simulations, that accounts for why a small sphere located at some space-time position (x,y,z,t) suddenly "decides" to move against the gravitational field; there is no theory of consciousness that "explains" why I chose to throw up a ball. Oh, I certainly register the fact that the ball has been thrown - i.e., I am "conscious" of having done so after I've done it - but I have utterly no idea why I chose to throw it at the time I threw it. Bejamin Libet has studied this fascinating phenomenon in the laboratory (see Mind Time), and has found that consciousness is actually far from a vehicle of willful intentionality; indeed, its real purpose may be to negate possible actions, not - as we have been taught by convention - to create them.

Why am I choosing the words I'm typing now, and not others? How are they forming in my mind (and, while we are on the subject, what is mind?) I am aware of having "written", but I am at a complete loss as to explaining why I chose the words I did; nor am I able to "explain" why they emerged when they did. They "come out of me," as if by magic; and I have little, or no, "control" over what they are or when they will form. My conscious self reflects back on their existence, but appears blissfully unaware of the process by which they were created.

So what does all of this have to do with photography? Everything, really; the creative act of photography is a microcosm of our general state of conscious experience. In my previous blog entry ("Experiential Flow in Photography"), I wrote of how the best photography is usually done when the photographer is in a state of flow; in which many of the attributes of "self awareness" - or consciousness itself - vanish. In truth, though, every single photograph is a result of (at least an instant's worth) of a "lack of consciousness." When I press the shutter, at that instant, I am completely unaware of why I have done so. It is important to understand exactly what I mean by this. I do not mean that I have idea of what I am doing. Clearly, I am out taking photographs, and I am fully aware of this, even as I press the shutter. But when my finger physically moves down on the shutter button to initiate capture, I have absolutely no idea why that act did not occur a microsecond before or a microsecond after. Indeed, if Libet's research is to be believed, the best I can say is that I become aware of having pressed the shutter button only after I have done so, but in no other way has my consciousness been an active participant in the process that led up to pressing the button.

The act of taking a picture thus presents the photographer with both a puzzle (about who we really are, apart from the role we play in helping the universe take a picture of itself) and an opportunity to learn something about the universal core of the creative process and consciousness itself.

What I sometimes do (when I can retain enough of my self-awareness to remember to do this;-) is to try to minimize the time between which I have pressed the shutter and at which I become conscious of having pressed the shutter. This is not at all as "easy" at it may sound. It requires a razor-sharp Zen-like focus on the process and the moment; and is, at heart, obviously antithetical to the "photographic flow" process, as described in my earlier blog entry. It harbors a bit of a paradox: the deeper one is immersed in the "flow," the less able one is to "reflect" on the process and "understand" the unconscious instant of capture; on the other hand, the "easier" it is to reflect on the process, the less likely it is that the process being reflected upon is the one of deepest interest (i.e., "flow"). Paradox - unavoidably it seems - always lurks around questions about consciousness; and just as mysteriously, it lies at the very heart of the creative process.

The Allure of Abstraction and the Difficulty of Defining It

"Abstraction allows man to see with his mind what he cannot physically see with his eyes... Abstract art enables the artist to perceive beyond the tangible, to extract the infinite out of the finite. It is the emancipation of the mind. It is an explosion into unknown areas." - Arshile Gorky

I have written about abstraction, at least as it applies to photography, a number of times on my blog. But always more implicitly rather than tackling the subject head-on; musings lurked in the background and served more as highlights and accents to the images rather than the main source of discourse. I've certainly posted more than a fair share of abstract images, since that is what my eye responds to most strongly. Indeed, my last three major projects were all heavily abstract: micro worlds, mystic flame, and glyphs. So abstraction is obviously on (and "in") my mind, quite strongly. But I'm not quite sure whether it's more my inner "I" or my outer "eye(s)" that is responsible for abstraction being such a deep rooted meta-pattern in me. So that's the subject of this post.

So, "What is an abstract photograph?" A simple (but far from complete) answer is that it is any image that does not depict anything that is "obviously" representational. By that I mean, whatever shapes and forms it appears to depict, none (or, at most, only a small subset) of them are obviously something that is recognizable; or, if it is recognizable, it is not uniquely so, as the shapes and forms can be interpreted in multiple self-consistent ways. This loose definition also allows for innately recognizable "objects" to be assembled (or composed) in an otherwise unrecognizable way (or that renders the collective unrecognizable as a whole).

A recent editor's note in Photo Techniques magazine (by Jerry O'Neill, Nov/Dec 2008 issue) revealed that Google is about to embark on a massive image cataloging task, in which it is anticipated that upwards of a trillion images will be parsed and indexed according to their content, rather then (as done now) by label. While the methodology to be employed is naturally left unspecified and proprietary, undoubtedly it will consist of some kind of AI-assisted pattern recognition of specific features and rudimentary scene analysis (such as facial contours, buildings, trees, water, and so on). It will be interesting to see what technique the Google researchers have come up for recognizing and indexing abstract images; i.e., images that do not contain anything "obviously recognizable." Will there be primitive categories of tone, shape, and texture? (Which apply equally well, of course, to non-abstract images!) How will an ostensibly "obvious" head shot of a horse, say, differ in Google's catalog from another one in which the contours are deliberately cropped (focusing, say, only on the mane of hair) and facial features either blurred or photoshopped away, rendering the image all but unrecognizable? At what point will one type of image transition into another? Even more simply, beyond referencing an image as "abstract" (by what measure?), what finer distinctions will be made in that class, and how will they be defined?

Google's laudable objective is to provide users with a way to find images according to what they innately depict, rather relying on someone else's depiction (via external label or reference) of what the images contains; and to do so automatically, by scanning the image itself. The problem, with both practical and philosophical components, is that the more abstract the image, the more difficult it becomes to distill it into a few simple features.

In some ways, this reminds me of an idea in theoretical computer science that has do with how one can tell whether a sequence of numbers, say, is random. The mathematically precise way of distinguishing random from nonrandom sequences, is that nonrandom sequences may always be compressed into something shorter than themselves; a random sequence cannot. Thus an otherwise infinite sequence that starts out and continues ad infinitum as "111011101110..." may be compressed by the much shorter (than infinite) description, "an infinite sequence of the symbol set 1110." In essence, one exploits an inherent pattern or symmetry, and uses that innate feature to compress information; or to more optimally express the information content. But a truly random sequence cannot be compressed into anything shorter. In order to communicate what the sequence is to someone else, one must exhaustively list each symbol that appears, for as long as patience permits.

However, some special random sequences, like the digits of Pi=3.14159..., may yield to a compressed description, such as "sum this infinite series..."; which raises the intriguing question of whether there are "special" abstract images in art and photography that similarly yield to "simpler" distillations? One possibility is that while some abstract images in the sense defined above are "random" (in a mathematical sense) and therefore are generally unyielding to distillations, there are also those that - despite not depicting any obviously recognizable thing - nonetheless evoke (in some quasi universal way that depends on the viewer's cultural background, for example) some obviously recognizable feeling (or a subliminal mood). A long time-exposure of waves in the ocean far from shore may not at all be "obviously long time-exposures of waves" (and thus not easily conducive to simple distillations: I wonder how Google's indexing will handle this case?), but may evoke very similar emotional responses in different people. An aesthetic compression based on evoked emotion rather than on the objective content may be much more useful in such cases. On the other hand, some other abstract, one that is perhaps created very artistically using some clever combination of light and shadow, may neither depict anything "obviously recognizable" nor evoke any universally shared feeling. A multiple exposure of a dozen separate shots, each of which is itself an "abstract" might be an example. I'd also be interested to learn how Google will handle such examples.

As for the philosophical dimension of abstraction, at least for me as a photographer, I tend to use abstraction in the classical (Alfred) Stieglitzian way; i.e., as "equivalents" of my inner emotional or cognitive states. Of course, I fully understand that there is a much greater chance that the viewer will not respond to an image in a way that mirrors my inner state when I created it than that the image conveys to the user what I really felt when I pressed the shutter. There are simply too many variables impossible to account for or control. But it is also often true (at least for me) that it is impossible to convey the feelings I have about a subject or scene without resorting to abstraction. It is certainly not true in all cases (sometimes a red barn is exactly what I need to express the beauty of redness). But as I grow as a photographer, and experiment with new techniques and ideas for projects, I am finding my artistic path moving ever more deeply into the abstract part of the aesthetic forest.

Perhaps, just as there are no "simplifications" of truly random number sequences, the purest form of abstraction is the one for which there is no better distillation than the abstraction itself. Then again, isn't that generally true of all art?

Color vs. B&W...a "Heisenberg Uncertainty"-like Relation?

In my last post, and immediately on the heels of returning from a trip my wife and I took to Greece, I noted that Santorini = geometry + color + shadow; emphasizing color, in particular, and brazenly declaring that Santorini is glorious, breathing, living, and sometimes blindingly bright color.

While I do not back down from those words - indeed, as I look over my growing portfolio of finished images and a selection of draft prints, I am, if anything, even more enamored of the "full color" results - an interesting thing happened as I went back (a second time) to process a few images in black and white: they reminded me of how awestruck I was when I first gazed onto the strange Escher-like Santorini architecture.

To be sure, what struck my eye first (or so I remember) was Santorini's blazing color; and my first emotion was pure joy - joy at being on a long awaited and much needed vacation with my lovely wife, joy at finally arriving at such a magnificently beautiful place, and joy at looking forward to discovering yet-unseen but sure to be wondrous sites. Consequently, when we got back home and I started processing my images in my usual style, I was struck by how much of my raw joy was missing from the black and white images. However, the color images instantly evoked many of the same feelings. My earlier blog entry thus followed naturally.

So what happened afterwards, and what is the point of this new entry? The answer is both "simple" and subtle...and, for me, a source of an important lesson I ought to have learned long ago. After working on over a 100 or so color images, and taking a few days "off" (while working on other, much older images having nothing to do with Santorini or Greece), I went back for a second look at my Greece files. I must emphasize that as I managed my usual black and white workflow, I did nothing objectively different from what I had originally done upon our arrival home from Greece (and what had originally resulted in my decidedly negative reaction, compelling me to work in color). But this time, even after completing only the first few files, I was struck by how powerfully the black and white images reminded me of the unbridled awe I felt at simply being in Santorini and finding myself amidst its magnificent architecture. This awe was not, strictly speaking, an emotional awe; it was much more akin an intellectual awe. My experience of witnessing Santorini's architectural splendor unfolding before me reminds me of the first time I gazed at an Escher print (which eventually resulted in a lifelong pursuit of math and physics). The point is that I had (at least) two layers of experience with Santorini landscapes; and that both cannot be simultaneously expressed equally as strongly in a single type of image. While the color images most strongly evoke the purely emotional side of my experience, the black and white images most strongly evoke the purely intellectual and cognitive side of my experience. Interestingly, neither type of image - alone - suffices to express the full depth of my experience. (This vaguely reminds me of Heisenberg's uncertainty relation between complementary variables, such as position and momentum, on the atomic scale).

Why had I not noticed this the first time around? I think it is because my emotion - or, rather, my strong desire to express my emotion of being in Santorini - was so overwhelming, that the secondary component of my experience in Santorini (a somewhat more detached intellectual "awe" of its geometry) was lost in the process. Yes, the color images vivdly convey the blazing light and glorious color of the island; but they also leave little room for any reaction other than a joyful exhuberance. The focus on color in my color images is necessarily so strong, and so dominant, that even the photographer's own eye is unable to discern the other - equally as important - dimensions of the original experience. In a sense, going back to the original files and "revisioning" them in black and white (although, truth be told, that is how I originally "saw" them while I was composing; I chose to retain the color afterwards only because the color reminded me of what I felt in Santorini, not because that is how I previsualized the images taken there) is my answer to Minor White's well-known admonition to use photography to tell the viewer something about what else the subject matter is. My color images show you what Santorini is; my black and white images tell you what else it is.

By stripping away the color, by focusing exclusively on only two of the three dimensions - geometry and shadow - I can more easily express the emotionally less charged component of my experience. Since color is absent, it is no longer the "distraction" it is in the color versions of the same images. The viewer is forced to interpret an image in terms of form and tone alone; and, hence, in Santorini's case, in terms of geometry and shadow.

And as for my lesson...? The lesson - I warn you it is a "trivial" one, but one I obviously needed to "relearn" at best - is that a single image can be used to express markedly different emotions; the "emotion" being a function of how the original captured (or raw) image is processed. Indeed, since my experience of Santorini (as of any place I visit, including places I know as well as my own backyard) is obviously multidimensional and is far deeper than "mere" joy and awe, I suspect that I will slowly discover multiple versions of the same underlying "raw" image captured by the camera. Collectively, and over time, these "expressions" will tell an increasingly more refined (but forever incomplete) story of my experience in Santorini. And I will continue to search for ways to bring out (and discover!) certain aspects of my original experience; undoubtedly focusing on one particular dimension at a time, at the expense of another, complimentary one (perhaps best expressed by some other expression; or "performance", as Ansel Adams likened a print to a negative). But, of course, that is precisely what photography is supposed to be all about :-) (Shows how much I have left to learn!)

Santorini (Greece) = Geometry + Color + Shadow

Regular readers of my blog, and those that have seen my work in Lenswork , Focus, and Black & White magazine, know that I am primarily (indeed, almost exclusively!) a black and white photographer. While I have dabbled with color in the past, and print in color on occasion (the last time involving images taken in Hawaii, with an "explanation" provided by this 2006 blog entry), almost everything I do "seriously" (and seriously try to sell) is in black and white. O'Reilly publishing also published a "color portfolio" (of sorts) of some flowers, but these were considerably older than the "2005" byline date would suggest, and - moreover - were never meant to be part of a larger body of work. Generally speaking, and without apology, color is simply "not my thing."

So, it came as somewhat of a shock to my system to learn that Santorini, Greece - a veritable paradise of color, geometry and shadow that my wife and I were fortunate enough to visit for a few days earlier this month - effectively makes a mockery of everything I held sacred about black and white ;-) Trying to render Santorini in black and white, even if duo- or tri-toned, would be like trying to convey to someone who had never heard of George Carlin what his "seven words you can't say on television" are without uttering what those words are, and doing so in a PG manner. Simply not possible.

While I tend to "see" the world in tones, not colors (a habit I think I first picked up when my eyesight started going bad when I was five; since - without glasses - the world is made up mostly of featureless, colorless splotches in my visual field), I recognize that when color is the primary - or otherwise important - focus of my aesthetic attention and therefore needs to be expressed, it behooves me to render the scene in color. But color is by no means my primary focus. And to the extent that my (mostly B&W tonal) aesthetics dictates how I perceive a photographic environment, and what grabs my attention in the photographic environment, it is simply a fact that I have seldomly produced a body of work consisting of color images. However, Santorini renders all such musings and intellectualizations absurdly moot. Aside from its intricate labyrinth of criss-crossed and interlocked walkways (that passerbys must occasionally share with mules), Santorini is nothing but color; glorious, breathing, living, and sometimes blindingly bright color!

I am convinced that color is somehow born and nurtured here, before being unleashed in muted tones elsewhere in this world. A result partly of the eternally bright midday summer sun and partly of the bright local hues and saturation, Santorini is ablaze with color. This is somewhat of a paradox, as most of the buildings are painted a bright white, and are devoid of any color; of course, this accentuates the omnipresent colors that much more and renders them, if anything, more intense.

Since we were there for only a few days, I regret not having the time to "attune" myself to the fantastic - and phantasmagoric - Escher-like architectonic forms. I was more in "point and shoot" mode, trying to capture as much of the colorful geometry as I could in the time we had, than in my more usual slow, deliberate, and contemplative frame of mind (which, had I followed, would have resulted in far fewer shots; perhaps none at all (!). As it turned out, I did manage to find several wonderful scenes that show some of Santorini's unique charm (though I'll let kind readers judge for themselves).

On a physical side, what I will always remember about Santorini is the steps; endless steps, ups and downs, and more endless steps ;-) My wife and I needed about 80 steps or so to get down to our hotel room from the main desk (which is itself about 75 steps removed from the "top" of Fira, the town we stayed in), then another 50 to arrive at the hotel's restaurant for dinner. It is the first place either of us has stayed in with the amusing (and slightly surrealistic) property that, if - after locking your hotel room and before arriving at the hotel's restaurant - you suddenly remember that you have forgotten something absolutely vital for the rest of the day, you will pause, in mid-step, for considerably more than a few minutes (partly to catch your breath and partly to just think), reflecting on the pros and cons of going back to the room for the item; and, 9 times of of ten simply decide to forget it. This place is just hard on the legs and lungs! Though we were both immediately winded less than half-way up the first series of steps the first day there, we soon acclimated to the mini-climbs and were hardly out of breath by the last day. Just in time to prepare for our hike down Samaria Gorge on Crete, our next stop; but that's another story. (We also both found our thighs had expanded two or three inches in girth with pure muscle after we got back home.)

I have posted a mini "point and shoot" portfolio of Santorini's Geometry, Color, and Shadow - (no B&W to be found anywhere ;-) - here.

Mystic Flame Portfolio

After devoting almost four months of work to my Micro Worlds portfolio (which I'm delighted to announce has recently been published in Lenswork issue #76, print and extended DVD editions) - a project that required me to be painfully hunched over my tripod like a old pretzel - I naturally wanted to choose a follow-on project that would give some much needed rest to both my back and eyes. But I didn't necessarily want to back away from the kind of abstract images that make up Micro Worlds. Indeed, while I've always been attracted to abstract forms (perhaps driven there by my admiration - awe even! - of my dad's paintings), I am finding my photography descending to ever deeper levels of abstraction.

And so, in a step that seemed a natural one to take (at least I could temporarily free myself of a tripod and not be scrunched up for hours on end in some inhumanly back-breaking stance; see my attempts to photograph a time exposure of fast breaking waves at Miami beach in a stiff wind to see an example of just how inhumanly scrunched up I can get!), I turned my attention to the wonderfully abstract and ephemeral patterns of fire.

“All things, oh priests, are on fire . . .
The eye is on fire;
forms are on fire;
eye-consciousness is on fire;
impressions received by the eye are on fire.”
- BUDDHA

All one needs to start a fire is some flammable or combustible material and an adequate supply of oxygen (or some other oxidizer). Subject the two to enough heat to initiate a chain reaction and...voila. On a more technical level, fire - or, more precisely, combustion - involves a complex series of molecular interactions. The burning of even comparatively "simple" few-atom molecules may involve more than 100 unique chemical reactions. The flame itself is an exothermic, self-sustaining, chemical reaction that produces energy and glowing hot matter (a tiny fraction of which is plasma). It emits both visible and infrared light; though the actual frequency range is a function of the chemical composition of the burning elements and intermediate reaction products.

Aesthetically, flames can be quite mesmerizing; displaying rapidly shifting patterns and complex nested tones and textures. Of course, capturing such patterns presents somewhat of a challenge, not unlike that of capturing images of flowing water and breaking waves. One cannot readily predict what specific patterns will arise. The best one can do is get whatever equipment will be used (camera, lens, tripod, exposure time) in place, and take as many shots as necessary so that interesting patterns can be "discovered" after the fact.

As I've only just started my new project - with the working title, "Mystic Flame" - I can offer but a small preview of shots to come. But judging from the results thus far, I foresee this project consuming at least as much attention of my photographic eye (and passion) in the coming weeks (months?) as "Micro Worlds" did before it.

Please click here to see my - still quite nascent - Mystic Flame portfolio. What you will be seeing are actually digital negatives. That is, a collection of reverse-toned images in which the darkest portions (of the "real" image) appear the lightest, and the lightest portions appear darkest. The most striking feature of these photographs, at least from a philosophical point of view, is that they provide a glimpse of the unseeable. Because the exposure times for most of these images lie between 1/500th and 1/4000th of a sec - or, in a slice of time that is far shorter than what our eyes need to "see" (and/or discern) patterns - they depict a reality that is fundamentally inaccessible to us. Yet here it is...simultaneously a beautiful enigma revealed, and an invisible reality not quite completely exposed; for once a pattern is "captured" by the camera, its ephemeral form vanishes forever.

Selection, Selection, Selection,....

Michael Reichmann, author of the wonderful blog Luminous Landscape, recently posted an interesting essay on the convergence of still and video photography. Citing such new cameras as Casio's EX-F1 and the Red Scarlet (which can shoot 60 frames per sec and 100 fps, respectively, without mechanical shutters, and at speeds approaching 1/40,000 sec), Reichmann suggests that new technologies are harbingers of a future in which the distinction between still cameras and video cameras is blurred, if not made moot entirely.

His assertion is both well argued and nuanced, and I encourage interested readers in clicking on the provided link to enjoy the article for themselves. For my purposes here, I'd like to focus on the aesthetic issues that such a convergence of technologies portends; and will argue that the distinction between "still" and "video" is - artistically speaking - somewhat of a red-herring.

While still photography and videography obviously represent two objectively distinct modes of expression, the distinction has heretofore been largely a technological - not artistic - one (I hope to explain what I mean by this in what follows). Because the two technologies have up until now been sufficiently "different," they required an artist (note I do not say photographer or videographer, but artist, because I think the category must now be made larger) to invest (sometimes huge amounts of) time and dollars in two sets of "still" and "video" equipment. What the technological convergence is leading to - indeed, what it already has led to, judging from cameras such as the EX-F1 - is a time when all serious artists can now use one and the same recording instrument to express their artistic sensibilities. The real issue is "artistic expression"; or what the artist wishes to convey with his/her art, be it still photography or videography. And what lies at the heart of any form of expression is selection; indeed, an almost endless (and endlessly nested) sequence of selection upon selection upon selection. The fact that the act of "taking pictures" has now become essentially synonymous with "taking videos" only serves to emphasize the fundamental role that "selection" plays in the creative process. And that part, at least, has not changed; if anything, it is becoming more difficult to do.

Consider the basic steps that any traditional photographer follows when approaching a subject and, ultimately - after recording and processing the images in either an analog or digital darkroom - using some medium (print, folio, gallery exhibit, or book) to express and communicate a "vision." Each step entails a myriad of decisions - or selections - that a photographer needs to make to complete the work. The not-quite-infinitely-long chain of selections begins with a basic question: "What does the photographer wish to express?" Is it a feeling? A thing? A sense of place? A sense of family? A still-life? The list is almost endless, but a selection must at some point be made. Once made, the photographer must decide on where to go to "find" (or "search" for) pictures.

Having arrived somewhere, the real work begins. In no particular order, and from a first-person perspective (speaking from my own inner experiences): What grabs my attention? Where do I look? Where do I stand? What light do I need? What do I exclude? What lens do I use? What f-stop/exposure-time combo do I use? Do I need to change the ISO? Do I need a filter? Should I shoot a sequence? Should I take a couple of different perspectives? Do I need to position my tripod any lower or higher? I could go on, but the point is clear. While most of this is automatic, much of the "creative process" consists of making a repeated series of selections.

Of course, the need to "select" continues (intensifies even) after we get back to our darkroom. What images do I keep (and "work on")? What software do I use? What factors need adjustment? White balance? White/black points? Tonal distributions? Shadow noise? Global/local contrast? Dodging or burning? Toning? Sharpening?

Now, suppose you've processed dozens (or hundreds) of images for a shooting project, and are ready to start thinking about what needs to be done to "communicate" a vision to an audience. More selection. Which images do I use? What sequence of images do I combine? What manner of expression do I use? If a book, how many to a page, and in what layout? If a gallery, what is wall placement? One row or two? How large should the prints be? ...the list goes on and on. And so we come full circle to the new cameras, such as the Casio EX-F1, that purportedly blur the distinction between still and video photography. While the fact that the distinction between these two technologies is becoming more and more blurred is arguably and demonstrably true, the deeper question is, "How does the lack of any distinction impact the creative process?" If one accepts the premise that art, in the broadest sense, consists of however many selective steps a given artist needs to go through in order to express (in some form, of the artist's choosing) an original idea or feeling, then the only way in which a convergence of still-video technologies impacts art is in providing the artist a richer set of technologies for recording and expressing images.

The question of whether what results remains "photography" (albeit in a different form), changes to videography (but, again, different from more traditional forms) and is no longer photography, or becomes some as-yet undefined "hybrid recording process" (that is different from either of its two historical antecedents), seems to me to be the wrong (or, at least, not most meaningful) question to ask. A better question is, "In what ways will artists adjust their creative process to find a better way to express their artistic vision?" It may turn out that some photographers find great artistic merit in having not one image (or only a handful of images) with which to express their vision but an entire movie; and/or find clever ways to combine still and "moving" images to expand their repertoire of artistic expression. The way in which they "do art" will therefore change, and the "art" that they eventually wind up doing may bear little or no resemblance to what may have in the past been called "photography." Other photographers, earnestly trying out the new technology for the first time, may find themselves overwhelmed with the now thousands of images from which to choose the "right one" - where before they had to sift through a few or at most a dozen - and either walk away from the new technology or (regrettably) take a step backwards as artists. Annie Lebowitz, in a PBS documentary of her life's work, admitted to having virtually no editorial skill when it came to selecting the one or two images that would make it into print from a shoot; a task she was more than happy to leave to the editors. Being good at one aspect of the creative process - or being good at making some "artistic selections" - does not guarantee the same success for other aspects of the creative process or ensure that the photographer will be equally as adept at making all required selections. In the unfortunate event that some new technology enlarges the "selection space" in precisely the dimension in which a given photographer is least gifted as an artist, it behooves that photographer to proceed slowly.

For many photographers (particularly those still working with "analog" large-format cameras), the convergence between still and video recorders will likely make no difference whatsoever. Their art will remain what it is, and evolve as it has and will continue. Still others will inevitably forge a new and unanticipated path - and an entirely new form of art - for which we do not yet have a handy label or phrase, and the nature of which none of us, at the moment, are prescient enough to predict or imagine.

Art, by its nature - and as life - grows, adapts, and evolves. In time, perhaps the very words "art" and "photography" will be supplanted by something else; and, in some future time, be recalled by historians as archaic "symbols of something that used to be done using some older forms of technology." But whatever the new words will be that convey the essence of what we now call "art," I suspect that the creative process itself will remain fundamentally unchanged. And what lies at the core of that process is selection, selection, selection, ... (as determined by the artist's soul).
