If the Doors of Perception..."

Morpheus: I'm trying to free your mind, Neo.
But I can only show you the door.
You're the one that has to walk through it.
- Matrix (1999)

"If the doors of perception
were cleansed every thing
would appear to man as it is, infinite.
For man has closed himself up,
till he sees all things thru'
narrow chinks of his cavern."
- William Blake (1757 - 1827)

Reality vs. Illusion vs. Perception vs. Understanding

“The camera is not only an
extension of the eye but of the brain.
It can see sharper, farther,
nearer, slower, faster than the eye.
It can see by invisible light.
It can see in the past,
present, and future.
Instead of using the camera
only to reproduce objects,
I wanted to use it to make what is
invisible to the eye — visible.”
Wynn Bullock (1902-1975)

Sting, Goethe, and the Creative Process


"Basic characteristics of an individual organism: to divide, to unite, to merge into the universal, to abide in the particular, to transform itself, to define itself, and as living things tend to appear under a thousand conditions, to arise and vanish, to solidify and melt, to freeze and flow, to expand and contract....What has been formed is immediately transformed again, and if we wish to arrive at a living perception of Nature, we must remain as mobile and flexible as the example she sets for us." - Johann Wolfgang von Goethe

My wife and I recently went to Sting's Symphonicities concert, when his tour stopped by in northern Virginia. Apart from enjoying his music (backed by the Royal Philharmonic Concert Orchestra), and observing the inevitable aging of his/our generation first hand - there were many, many more 40/50/60-somethings at the concert than anyone who can still remember pimples on their young faces (my wife recalled the puzzled look on the face of our 17 year old baby sitter when she told her where she and I were going for the evening; "Sting who?" she asked), the evening gave us a chance to muse on one of the reasons for Sting's longevity, and what it may say about the creative process in general.

There are some who have criticized Sting's recent forays into decidedly non-traditionally-Rock-like music oeuvres (such as with his If On a Winter's Night and Songs From a Labyrinth albums). And his most recent Symphonicities album has been described as same-ole / same-ole embellished with a full orchestra (an overly harsh assessment, IMHO, as much thought and craft obviously went into integrating new voices and new accompaniment). Of course, it is precisely by continually venturing into new musical territories and challenging himself to rework older material that Sting stays a potent musical and creative force. Sting also challenges us to consider just who "Sting" (or any artist) really is, and whether being content with "sameness" is a form of artistic decay, at best, or artistic irrelevance, at worst.

Ansel Adams, with his piano skills, was fond of comparing the relationship between prints and original exposures to performances of scripted musical scores; and was equally fond of "reworking" old plates with new techniques or aesthetic sensibilities. The "Ansel Adams" of 1980 was similar to but not entirely equivalent to the "Ansel Adams" of 1960 or the "Ansel Adams" of 1940. Yet we use the same "name" to refer to all three periods, and have a mental picture of the "same" Ansel Adams when referring to any of his impermanent historical versions. Szarkowski's Ansel Adams at 100 shows a few examples of Ansel's evolution as a printer (the difference between Ansel's original and 20+ year-later version of his well-known "Mckinley" print are particularly striking).

There is a deeper - philosophical / epistemological - problem lurking here, hidden in a seemingly innocuous question: "What is the difference between the 'name' of something that is alive - a flower, a pug, an artist, or an artwork - and the 'living being' itself?" Richard Feynman, the great physicist, told of an important lesson he was taught as a child. His father - a methodical observer of nature - delighted in sharing with his son his voluminous mental notes on the rich lives of all the birds that lived in their neighborhood; when they came out in the morning, what songs they sang, what food they ate, and so on. All of this his father learned on his own, not by reading books, but by carefully watching and listening to the birds for years and years. Young Richard's lifelong lesson came one day when his peers laughed at him for not knowing any of the birds' names, something he never learned from his father (who himself did not know). His father gently explained to Richard that he actually knew far more about the birds than any of his friends: "All your friends know is a jumble of sounds that help them point to a particular bird. Only you know who those birds really are!"

This holistic approach to "knowing" can be traced back to Goethe's way of doing science, an approach which Henri Bortoft (in his masterful work, The Wholeness of Nature: Goethe's Way Toward a Science of Conscious Participation in Nature) describes as "dwelling in the phenomenon" instead of "replacing it with a mathematical representation." It derives from the "simple" observation that living beings are growing, evolving processes that are as much "things in themselves" as interconnected components of lesser and greater processes. To identify any one state of such a being with the being itself - i.e., by using a "name" to designate "what the system is" at some arbitrary time during the course of its evolution (such as by taking a picture of a tree in your yard one day and calling it "the tree in my yard"; or by taking a picture of the Atlantic ocean from some beach on Long Island - see picture above - and calling it the "Atlantic Ocean") - is to miss completely what the being really is; namely, an organic instantiation of a continually unfolding dynamic process of evolution, metamorphosis, and transformation.

In describing the movement of metamorphosis in the foliage of a flowering plant, Friedemann Schwarzkopf (in his The Metamorphosis of the Given: Toward an Ecology of Consciousness), suggests that "...if one could imagine a person walking through the snow, and leaving the imprints of its feet, but with every step changing the shape of its feet, and if one would behold not the trace in the snow, perceptible to the sense-organs of the physiological eyes, but the living being that is undergoing change while it is walking, one would see with the inner eye the organ of the plant that is producing leaves."

And what of the lesson for the photographer? If only we could see the world as Schwarzkopf - and Goethe - suggest we see a plant! The inner creative process that drives what we do (why and what we choose to look at, what moves us, what grabs our attention and demands to be expressed) is just as much a living force as what we train our lenses on in the world at large. I would argue that in order to become better - more impassioned, more sincere, more artfully truthful - photographers, requires a more Goethian approach; it requires us to learn how to dwell in our subjects. Don't focus on objects or things. Pay attention instead to process; and revel in your own transformation as you do so.

Postscript. Goethe's The Metamorphosis of Plants has recently been reissued in a beautiful new edition. Highly recommended for anyone interested in learning about the "...how of an organism." For those of you wishing to pursue Goethe's approach to nature, I urge you to also look at two recent books: (1) Meditation As Contemplative Inquiry, by physicist Arthur Zajonc, and (2) New Eyes for Plants: A Workbook for Plant Observation & Drawing, by Margaret Colquhoun and Axel Ewald.

A Fine-Art Photographer's Must-Have New Book on B&W Printing!

George Dewolfe - photographer, teacher, workshop instructor and author - has just published one of the best books I have run across in a long, long time on the art and craft of fine-art B&W printing; called, naturally enough, B&W Printing.

Generally speaking, there are three basic types of digital-photography-related books on the market: (1) the beginner's guides, that walk the aspiring photographer / "camera user" through the steps necessary to take a picture, how to operate her camera, and how to download images to the computer and print them out on a small ink-jet printer; (2) the intermediate guides, that assume readers are already familiar with their camera but want to learn more about how to process their images for the web or prints; and are tailored to readers who are serious about their photography (certainly more so than casual "point and shooters," but do not invest more than a few hours on a weekend, say, or as "designated photographers" at family get-togethers and vacations; and (3) the advanced guides for affirmed afficionados of photography (who want to learn all of what Adobe's Photoshop has to offer, for example) and professional photographers (who may want to learn additional techniques or, if they are film-photographers, want to boot-strap themselves into digital photography). Each type of book is well represented on the market, of course, and there are many excellent books - classics even (the "advanced guides" by Martin Evening, Katrin Easemann, and Scott Kelby all come to mind).

But, thus far at least, the digital photography world has lacked a particular kind of voice that film photography has enjoyed for decades, simply because film photography has been around for so long. Namely, the voice of a seasoned fine-art photographer / printer writing about and dispensing with his years of experience as a photographer applied to the new, emerging digital imaging technologies. How many times have I picked up a book with a titles like, "Advanced Fine-Art Digital Imaging" by so and so, intrigued by the title and number of pages/examples, only to be disappointed to find either that the images in the book are at best serviceable as "fine art photographs" or, at worst, dismal examples of what "fine art" ought to be, or that the images are wonderful - perhaps even gallery-like in their presence - but that what I had hoped to learn by way of "digital craft" is nowhere to be seen, since the author is a fine photographer but less-than-gifted writer or Photoshop technician. The rarest kind of book of all is a book on fine-art photography - particularly black and white fine-art photography - that combines great pictures, great technical skill, and great writing. I have seen no finer example of this rare breed of book than B&W Printing, by George Dewolfe, published this month by Lark Books as part of their Digital Masters series.

As one can glean from his website, Mr. Dewolfe has been a photographer since 1964 and holds an MFA in Photography from the Rochester Institute of Technology. He studied photography with both Ansel Adams and Minor White in the 1970s. He also studied perception with Dr. Richard Zakia (a fact I mention because Dr. Zakia's book, Perception and Imaging, is among my all-time favorite books on the subject). Mr. Dewolfe has taught photography at several universities (and continues to teach photography and master print classes), and conducts workshops throughout the country. His works have appeared in numerous one-man shows and galleries. He was part of the development team behind Adobe's Lightroom software. He also authored one of the first (and best) "advanced" books on the craft of digital printing I purchased for my personal library (and still frequently refer to): George DeWolfe's Digital Fine Print Workshop.

And so we get to Mr. Dewolfe's new book, B&W Printing. What immediately sets it apart from 95% of related books on the market is immediately apparent after even a quick perusal of its 200+ pages: its subtle, almost understated, elegance. It oozes with quality, and attention to detail.

The images - all examples of one technique or another (except for a small portfolio toward the end that exhibits some wonderful "final" prints) - are each carefully arranged to highlight a specific approach, and are all expertly crafted and presented. Indeed, I suspect many a reader will look at the first such example that a chapter starts with - an out-of-camera image that Mr. Dewolfe displays to show the "before" part of a specific workflow, and wonder, "What can one possibly do to improve such a beautiful image?" ("Beautiful" both as a technically brilliant print, and as a fine-art photograph). The answer to which, of course, after reading Mr. Dewolfe's elegant prose - full of finely honed and expertly distilled advice on why something needs to be done, when and how to do it, and how to tell when its "done" - is "quite a bit." As the "final" image is revealed at the end of most chapters, the reader marvels both at its innate, shear beauty - Mr. Dewolfe's images all have a preternatural "glow" to them; they are carefully crafted in such a way that their ostensibly two-dimensional forms leak into a third "magical" dimension - and the relatively "simple" steps by which the original image was converted into it. Of course, it is precisely Mr. Dewolfe's gifted ability to describe what goes into these "relatively simple" steps - done in such a way that even a novice Photoshop user (albeit one who is well versed with the basic of aesthetics and photographic "seeing") can easily follow them and apply them to her own workflow - that sets this apart from most others and elevates it to the level of an instant classic.

The book consists of three main sections, and a portfolio at the end. A glossary and index are also provided. The first section discusses fine-art black and white photography in broad - but philosophically deep - terms. Great attention is given to the nature of "seeing" (by both camera and photographer), and the most important qualities that make up a photograph (tone, luminosity, luminance, sharpness, and so on). Though this may sound like so many other dry incantations of "obvious" material, perhaps done to death in other volumes, even here, in only the introductory parts of the book, Mr. Dewolfe provides something special. Using the way in which humans process visual information, Mr. Dewolfe astutely distinguishes between "luminance" (a combination of reflection and illumination, and which is essentially what both camera and retina "see" in any image) and "luminosity" (which is what we, as observers, "see" - or the way in which we interpret - luminance. It is the apparent luminosity of an image that gives the images its strength, its character, and ultimately, if the image is to express the artist's vision, its meaning. The best photographers are those that are able to expertly manipulate the raw luminance of their images into something that communicates how they "see" (and feel about) the world. This is a deep discussion of fundamental truths of the art of photography; but is not overbearing in any way; the typical reader will probably not even recognize that she has been treated to a master discussion of the very core of what defines fine-art photography. Needless to say, few if any books provide half the wisdom waiting to be plumbed in the first 60 pages of this magnificent book.

The heart of the book lies in the second section, and spans about 130 pages. Here you will read about designing a workflow, how to choose and setup your software, how to input your images (the author uses Adobe's Lightroom), how to make global and local adjustments to an image, how to fine-tune an image, and, finally, how to make the best use of your printing tools and methods. Each example is meticulously and lovingly presented, with each step described in both words and illustrated with screenshots (of workflow) and the effects interim steps have on a particular image. As a bonus, each chapter also includes sample workflows by featured artists (some of whose work I knew about before, but others were new to me and compel me to look up their work).

The third section contains some musings on the nature of photography, how to hone your skills as a photographer, and the art of mindfulness in art in general. The small, self-contained section on mindfulness perfectly illustrates Mr. Dwewolfe's best gifts as a teacher. In what amounts to no more than a page, Mr. Dewolfe provides - in sparse but artful, Haiku-like prose - a natural gateway toward applying meditation techniques to creating meaningful photographs; punctuated, in the end, by yet another beautiful, luminous image.

Mr. DeWolfe begins his book with the question, "What is a masterpiece?" By the end of the book, the reader will have seen a fair share of masterpieces created and crafted by Mr. Dewolfe's refined eye and skill. And the reader will leave the book behind (though no-doubt leaving it within easy reach to refer back to when necessary) knowing that she is now prepared to craft masterpieces of her own. Mr. Dewolfe has written a truly sensational book on the art of B&W printing, and one that is destined to become a classic in its class.

The only mild criticism I can make with regard to the book - though not of the material that appears in it per se - is that Mr. Dewolfe does not provide a discount code for readers of his book to use to purchase his PercepTool plug-in for Photoshop (which is an integral part of the workflow described in the book, and encapsulates much of what Mr. Dewolfe has learned during a lifetime of "seeing" as a photographer and as a student of human perception). I have seen other authors provide discounts for software in their books, but for software nowhere near as rich and far-reaching as PercepTool. I would encourage Mr. Dewolfe to do the same. But I make this criticism only in hopes of getting Mr. Dewolfe to reach an even larger audience with his teachings. Perhaps in the second edition?

The Eightfold Path Toward Self-Discovery Through Photography

A while back, I posted an entry called The Eightfold Way of the Artist, in which I describe the basic "steps" by which most artists - and most photographers (not that there is any meaningful difference between the two;-) - typically develop an aesthetic language over a lifetime's worth of "seeing" and "expressing" their own unique vision. That earlier discussion, however, was fairly abstract; and emphasized how the evolution of one's personal art may be used to reveal, over time, the artist "behind" the emergent work. I'd like to revisit this idea, but from a slightly more practical (but no less philosophically deep) point of view: namely, how the nature of the expressed art form itself changes over time, and what we - as artists - can learn from the forms of change.

In keeping with this entry's more prosaic tone (though, as I glance ahead to what I wrote below, I'm not sure how much "philosophy" I've actually stripped from my earlier post; I'll leave that up to the patient reader to decide;-), I should note that it was prompted by a disarmingly simple and straightforward question my mom asked me a few weeks ago (well, it was straightforward, but only before I realized that answering it - in a meaningful way - would prove anything but). Having just seen my Micro Worlds portfolio, my mom asked: "Andy, these are lovely, but why do you take so many pictures of the same thing? You used to show me such a variety of subjects; why the change?"

My immediate reply was accurate but shallow. I said that I no longer find individual images adequate to fully express what I want to communicate about what I'm seeing and feeling. My mom - who is not used to shallow answers about art, having lived with a rather deep artist (namely, my dad) for as long as I can remember - called me on my flippant reply, and probed for something deeper. I tried again: "I don't think in terms of individual images anymore; and when I see a subject that interests me, I want to explore it more, with multiple exposures and viewpoints." In some ways, of course, that was worse than my first answer...my mom countered with: "Andy, you've restated my question quite nicely. Now, how about explaining why you don't think in terms of individual images anymore?"What follows is a summary of the deeper answer I gave my mom after I took a few hours to ponder her probing question. I concluded that my mom very perceptively discerned a genuine meta-pattern shift in the gestalt of my photography; and that the essence of that meta-pattern shift provides an important clue as to what stage I'm in, in my natural (and still very much ongoing) evolution as an artist. I also thought that it might be a worthwhile exercise to think through, and describe, the various stages that I suspect most (if not all) photographers gradually move through as they mature as artists. While my notes contain the germs of ideas for "stages of artistic evolution" whose numbers range from a only a few to more than a dozen, I eventually settled on eight stages (perhaps an unconscious homage to Buddha's Eightfold Path).

Let me begin by stating up front that my description of the "8-fold path toward self-discovery" in no way implies that I have any special insight into the deepest strata of art or photography; it is offered simply, and humbly, "as is" and is to be read - and understood - purely as an expression of but one point of view (which the reader is entirely free to disagree with; indeed, I hope does disagree, with at least parts of it, so as to foster a dialectic by which we can all collectively probe the meaning of art and photographer even deeper).

"A man's work is nothing but
this slow trek to discover,

through the detours of art, these two or three
great and simple images in whose
presence his heart first opened."
- ALBERT CAMUS

Stage 1: Joyful snapshots of anything and everything. What is the first thing anyone who gets a new" toy" (or serious tool) wants to do? Play with it, of course; see what it can do, learn how to use it - mechanically, at least - and just have some fun with it. The beginning photographer - such as I remember myself being when I was barely 10 and my parents had given me a Polaroid instamatic camera for Christmas - doesn't really care much about anything other than taking pictures of whatever strikes their fancy. And that's precisely what they get: pictures of their dog or cat, their room, mom and dad, their own reflection, snapshots of their friends, a tree, a shoe, a baseball game, an apple, whatever. Everyone begins somewhere; and that "somewhere" for photographers is a joyful - but otherwise essentially indiscriminant - expression of a new found tool that takes pictures. And pictures they will take; all kinds of pictures, with hardly any rhyme or reason. In a basic sense, anyone who is alive and is the least bit curious about the world - and is given a camera, or any other artistic tool - instantly becomes a stage-1 artist.

Stage 2: A passive stirring of aesthetic value. As the photographer evolves from stage one to stage two, she still takes images of anything and everything that strikes her fancy but now finds that certain objects draw a deeper attention than others. Her gaze still falls on most everything that surrounds her, but her embryonic photographer's "eye" begins to discern that aesthetic value is not homogeneously distributed; certain scenes, and certain things, draw her eye more than others. For the first time, though perhaps weakly, some aspect of the environment draws the artist's attention. But the second stage artist is mostly passive, reacting to aesthetic stimuli as they appear and are recognized, but still largely undiscerning as to their relative merit and eager to "take in as much as possible." The stage-2 artist creates pictures in which others recognize that certain things are given more or less visual weight than others; but - because the stage-2 artist is still only a "beginner" - the pictures themselves are not necessarily as aesthetically pleasing as they could be.

Stage 3: Willful engagement of the aesthetic environment. The transition from stage two to stage three is both difficult to see "from the outside" (for observers of the artist's inner journey) and dramatic (as experienced directly by the artist). The transition occurs when the artist finds herself discontent with the merely passive capture of objects, and instead actively seeks objects she deems "interesting." She has started to categorize the world according to her own unique measure(s) of lesser and greater aesthetic value. Objects (or places, or people, or situations, ...) that the stage-three artist holds in high regard become beacons in the environment that both immediately draw the artist's attention, and are "attractors" toward which the artist actively makes her way. If the artist finds trees of particular interest, for example, she is no longer content with leaving a park with a "few stray shots of trees," but now deliberately goes to different parks (and other places that has lots of trees) to "see" as many different tree as possible. The stage-three artist begins to learn what she values most, and then goes out to find it. She also learns to better express what she "sees" and is better able to create aesthetically pleasing images. "Objects" of attention in the stage-3 artist's picture repertoire are no longer appreciated by others merely as objects that clearly "stand out" from the background, but as bona-fide "aesthetic elements" assembled by the artist's growing creative powers of expression.

Stage 4: Recognition of the power of expression. The transition between stage three and stage four is marked by a gradual recognition of the power of using photography - traditionally, a print - to express not the object itself, but what draws the artist's attention to the object. In practical terms, this means that the stage four artist is concerned less with depicting trees merely as objects of interest (in keeping with our "tree" example) - being quite happy to display a set of "shots of pretty trees" that are otherwise unremarkable in any way - and more with finding the one shot (and the one resulting print) that best expresses to others why the artist loves to photograph trees. This subtle (and not so easy) transition represents a very significant worldview shift; as well as a shift in artistic sensibility. Indeed, many artists (myself included) find themselves "stuck" at the boundary between stages 3 and 4 for years, as they patiently develop and explore ways to express meaning, and not just being. Making matters even more difficult is that the stage 3->4 transition involves a gradual recognition of - and increased attention to - two different worlds of reality and expression: (1) attention to using a print to isolate the tree as it "appears" to us, as an otherwise embedded feature of the external environment, and (2) attention to using post-capture tools (either in a traditional or digital "darkroom") to properly express the most "important" features of the tree as captured in a photograph. Again, this distinction is both subtle and deep. It is meaningful only insofar as the stage-4 photographer realizes there is an important aesthetic difference between using tools to render differences between trees and their environment (in order to "make them stand out" better from the surrounding clutter), and using tools to selectively render the inner parts of a given photograph (the first inkling to dodge, burn, and make other tonal "changes" to an image), so that the viewer can better "see" what the photographer is trying to express. The slow and careful learning, nurturing, and refining of these skills can (and often does) take years, if not decades, to develop fully.

Stage 5: One picture is not enough. Sooner or later, but only after comfortably settling into stage 4, every artist yearns to go beyond the "image" - to go beyond just showing a single picture, or at most a few individual prints, of a subject the artist holds dear. More effort and more care are put into every single capture (and its attendant post-capture processing); and more and more finished prints are deemed "worthy to show others" by the artist. But the stage-5 artist also grows increasingly dissatisfied over what she is beginning to perceive as "too shallow" an expression of an inner vision that is slowly trying to make its own voice heard. "I like this tree," she finds herself thinking to herself more and more often, "but it doesn't - can't ! - by itself express why I've been taking pictures of trees for as long as I have." She continues, "Each of my trees is lovely, and I'm proud to show them to others, but I'm somehow missing the bigger picture here. It is as though each of my pictures is a chapter in a book yet to be assembled." The artist may not yet quite know what this nascent "book" is, what form it will eventually take, or what it will "say," but her aesthetic eye has measurably raised its line-of-sight to higher levels. The stage-5 artist no longer thinks (or "sees") in terms of individual pictures. Rather, the world is seen as a patchwork; a tapestry of overlapping images. Or, simply, in terms of groups - or portfolios - of pictures.

Stage 6: Telling a story. Inevitably, the artist becomes interested in not just putting together a set of assorted - but only marginally related - prints (as in collections of "best of" shots), but in carefully crafting and sequencing the images in a portfolio of prints to tell a specific story. If the original interest was (and remains) trees, for example, the artist now wishes to move beyond her ever growing collection of "individual trees," to a new form of expression designed to reveal both how "sets of trees" are related, and a bit of the process by which the artist's perception and expression of her general "love of trees" has itself evolved over time. The stage-6 artist thus naturally steps away from a focus on prints as prints (even if they are otherwise a part of a larger collection) and moves toward an increased focus on portfolios of interrelated images. It is no longer enough to just find that one "good" or "best" image - even if it is one for the ages (though any artist is always happy to find it! ;-) - the artist now first thinks in terms of mutually related groups of images. Ideally, each image both stands on its own and compliments and/or enhances all of the others. In more practical terms, the artist now wishes to express not so much her love of "trees" per se, as represented in the "best possible way" by a single image, but a deeper aesthetic experience of trees in general; as exemplified perhaps by a selection of personally meaningful images captured in a favorite park, or accrued over several weeks or months (or years) even as the artist explores other subjects and themes. The stage-6 artist's attention has moved from "pictures" to projects that culminate in portfolios of interrelated images; all motivated by a growing desire to use sets of images to tell a story about what the artist's eye (and heart) is drawn to, and why..

Stage 7: Portfolios of Portfolios. The penultimate stage typically appears only when an artist has attained a certain level of "aesthetic maturity"; by which time a meaningful body of work - consisting mostly of portfolios (though "individually meaningful" images still pop up from time to time) - has naturally emerged. Each and every portfolio has both a story to tell, and is an element of an as-yet unrevealed and unrealized deeper story; a story about which the stage-7 artist hears the first faint murmurs of. A story concerning the truths of the world "out there" as revealed to the photographer through her lifetime's worth of aesthetic judgements as to what to shoot, what to keep, how to express, what to show, and what to sequence into portfolios. The artist realizes that her art has not only captured an aesthetic impression of the world - an aesthetic that is uniquely hers, though the details may overlap with that of other artists - but is a manifest imprint of a deeper aesthetic order of the external world. The artist begins to understand and appreciate certain universal objective truths by examining the subjective aesthetic order that she herself has "imposed" on the world. By studying her own portfolio of portfolios - as though her life's work was itself a "world" open to capture with an aesthetic eye and camera - the artist discovers universal truths about the world itself. In my own case (though I suspect I am far from moving into stage-5, much less stage-7), I can glimpse some of the feelings associated with a stage-7 worldview by looking inward to my motivation for creating my recent "portoflio of portfolios" called Sudden Stillness. Sudden Stillness consists of four fundamentally interwoven portfolios called Chaos, Order, Complexity, and Entropy. The subtitle of the book conveys the deeper meaning behind (and reason for the particular sequencing of images in) the book: visual echoes of timeless rhythms. Collectively, the four portfolios weave a "story" about the fundamental rhythmic patterns that regulate our world (from this one photographer's point of view, of course). In short, the stage-7 artist uses her own work - consisting now mostly of portfolios of portfolios - to transcend art and begin addressing deeper and universal themes and issues regarding the order of the world around her. Art is no longer concerned solely with the here and now - for its own sake, and regarding limited sets of objects, themes, and contexts - but assumes an added dimension of seeking a transcendent truth about the nature of the world itself. And part of that truth is revealed - to the artist - by the artists own body of work.

Stage 8: Self-discovery. Stage-8 is not all that different from stage-7, at least outwardly, and if measured objectively in terms of the artist's physical output (in terms of images and prints). The stage-8 artist still typically produces portfolios of portfolios, still diligently practices her artform, relentlessly striving toward perfection, and delights with each every "beautiful print" as though it was her first, just as she has always done and will always do; but the artist shows no outward sign of doing anything different from the stage-7 artist. Indeed, paradoxically, the stage-8 artist may even appear to others as being stuck on a plateau (albeit an aesthetically very high one), and no longer willing, or able, to "evolve" artistically. But something fundamental has changed - and in a dramatic way, but one invisible to anyone but the artist at first - in the way the artist understands and interprets her own work. Of course, all of the technical components of image capture and mechanical procedures of post-capture processing have long ago been turned into virtually reflex action on the artist's part. Without this being true - something that requires years and years of dedicated and full immersion in art - no artist can progress to stage-8 (this - namely, the need for total immersion - also appears to be universally true of any creative field, if the practitioner wishes to attain the highest levels of "creative accomplishment"). And what is the fundamental change that occurs? In the same way as we indicated that the stage-7 artist uses her art to uncover truths about the world, the stage-8 artist discovers truths about her own soul. The world, and the artist's own work, have both come full circle: the world revealed through an artist's vision; and the artist's expression of the world uncovering the depths of the artist herself. Seer and seen become one; and the seen brings the seer back to self.

“A man sets out to draw the world.
As the years go by, he peoples a space
with images of provinces,
kingdoms, mountains, bays, ships,
islands, fishes, rooms, instruments,
stars, horses, and individuals.
A short time before he dies,
he discovers that the patient labyrinth
of lines traces the lineaments
of his own face.”

Landscapes of the Soul

"The physical object, to me, is merely a stepping stone to an inner world where the object with the help of the subconscious drives and focuses perceptions, becomes transmuted into a symbol whose life is beyond the life of the objects we know." - Clarence J. Laughlin, Photographer (1905 - 1985)

For all those who've expressed, privately and publically, an interest in seeing some of my images in print - apart from my contest-winning Sudden Stillness book, to be published in short order by Envisage Press - I offer the following. A self-published collection of photos, entitled Landscapes of the Soul: Reflected Shadows of Self.

The book consists of four visual landscapes: Water Flow, Entropic Melodies, Spirit & Light, and Micro Worlds. Each offers an interpretation of spirit made manifest, and is introduced by a short essay. There are a total of 120 pages, 52 duotoned images, four essays and a short introduction.

Water flow shows glimpses of dynamic processes at work; though the processes themselves understandably remain hidden.

Entropic Melodies hints at the boundary between life and death. (A few images from this series appeared in a portfolio in issue #41 of Black and White Magazine.)

Spirit & light reveals the physical magnificence and splendor of sacred spaces, as created by human hands, though the spiritual object of devotion lies only in the heart of the observer. (Some of these images were featured in Lenswork Extended Edition #71 (July-August 2007)

Micro Worlds shows the extraordinary resplendent beauty that may be found even in abject banality, but only if the self recognizes that it is its own landscape of the soul. (These are taken from a growing series I'm still working on, and have previosuly featured in an on-line gallery.)

"To the vast majority of people a photograph is an image of something within their direct experience: a more-or-less factual reality. It is difficult for them to realize that the photograph can be the source of the experience, as well as the reflection of spiritual awareness of the world and of self." - Ansel Adams, Photographer (1902 - 1984)

My original intention for this project (when I started a few weeks ago) was to merely find an "easy" way to archive some of my work; for my own records. Indeed, I honestly wasn't expecting much by way of quality, although I grew increasingly intrigued by seeing references to the "quality of Blurb Books" on various forums and chat groups. Having my "test case" book in hand from this on-line publisher, I can now attest to its overall quality. Very impressive, actually.

Compared to the often less-than-stellar quality of books one sees even on the shelves at Borders, I have no qualms about offering the book for sale. While certainly not as good as fine-art prints (even the best books typically fall far short of that Holy Grail of course), nor even as good as the finest pigment-based ink jets I can produce for exhibits, the images in this volume stand on their own as beautiful book-form reproductions. Of course, the subject matter may not be to everyone's taste, nor the images themselves, but about that I have far less control;-)

For those who find my aesthetics pleasing, I am sure you would find this little collection of some of my recent images very enjoyable.

Doors of Perception

"There are things known and there are things unknown, and in between are the doors of perception" - Aldous Huxley (1894-1963).

A camera is a portal to both ordinary worlds and otherwordly mysterious realms. Sometimes the two coalesce, but only for an instant, and hint at other unfathomable and inaccessible universes; all teasingly poised just beyond the impenetrable boundary between what we see and ... ?

What lies beyond the door of perception? What meets our silent inquisitive gaze as we gently push it open?

Would what we newly see change everything we've ever known? Would the world we leave behind seem as incomprehensible to us as the one we enter? Are all but Shamans truly blind?

How shall we describe what lies beyond? Will our old words and concepts be enough? Or will they merely be useless relics of the past; meaningless symbols of a misaligned reality?

What happens when we discover a new language to express our strange perceptions (assuming that such a language even exists, or that we are clever enough to find it)? Will new categories emerge, subjectively partitioning our world into newly objectified parts?

Or will the new, still unrecognizable abstract forms suddenly revert back to old meanings (or appear to), subtly revealing even deeper recessed mysteries to be explored...?

What was the world like, I wonder, before I stepped into this one? Is there anyone left to understand my answer?

"As we acquire more knowledge, things do not become more comprehensible, but more mysterious." - Albert Schweitzer (1875-1965).

A "Magic" Filter from Singh-Ray

When I was still in my teens, and just starting to learn photography, I recall two pivotal moments after which whatever doubts I may have had at the time about seriously pursuing photography evaporated, never to be heard from again. I described the first moment in an earlier blog entry; it amounts to seeing Minor White's "abstract expressionist"-like "Capitol Reef" print for the first time. I will not repeat what I wrote before, except to emphasize the spiritual awakening that White's image evoked in me. I realized for the first time that photography could be used to express not just the "objective" world - as it appears here and now, on the "outside" - but also an intensely subjective, private world that describes our very soul and its relationship to the corporeal.

The second moment, which occurred at roughly the same time in my life, took place as I was ponderously reading a rather dry textbook on photography; and is a direct precursor of why I am now so excited (30 years later!) by a magnificent lens filter available from Singh-Ray. Going back to my old self at 17, I remember being curled up in bed one day, while skimming through some pages explaining the basics of exposure. It was all standard material, with equally standard (meaning somewhat "dull") illustrations and photos highlighting the central points of the text. And then I ran across what I, at the time, thought was a stunningly dull photo: an image of an empty highway, taken in broad daylight. No cars, no pedestrians, no birds, nothing but asphalt and concrete. "Wow," I remember thinking, "these guys could use some creativity pills if this is the best they can do to illustrate a text on photography!" But it was a curiously puzzling photo, and strangely mesmerizing in its own way. I couldn't take my eyes off it for some reason. I kept asking myself, "Why aren't there any cars on this long stretch of highway in the middle of the day?" After reading the text more carefully (there was no caption underneath the picture except for the figure number), I had my second epiphanous moment.

The reason the picture showed nothing but an empty highway was because - during the extremely long exposure (about 1 min!) - nothing was in the frame long enough to register on the film! And how did that happen? Because the author was illustrating an effect of attaching a strong neutral density filter to the lens (in addition to using a very small aperture). A neutral density filter (NDF) reduces the intensity of light (at all wavelengths), thereby increasing the effective exposure time as the amount of reduction increases. NDFs are typically rated by the number of "f-stops"-worth of light reduction they impose.

For example, if a "filterless" exposure at f8 is, say, 1/500 sec, then a "2 f-stop" NDF will increase the exposure to 1/125 sec (at the same aperture); and an "4-stop" NDF will further increase it to 1/30 sec. Of course, one has to be sure that the white balance is preserved (so that there are no extraneous color shifts); which in practice simply means that you'll be investing in more expensive brands. I always carry at least two NDFs in my bag, one 3f-stop and one 6f-stop. The range is important, for it allows me to "experiment" with, say, a "frozen" water stream (using a fast exposure), a stream that is delicately blurred (for exposure times between 1/4 - 1 sec), and cloud-like flow "abstractions" (for t>5 sec).

However, despite the aesthetic allure of photos taken with my NDFs, I have often felt overly constrained by being able to reduce my exposure only by a fixed amount, as allowed and defined by a given filter's f-stop rating. Until, that is, a few weeks ago when I stumbled upon a remarkable variable neutral density filter - called a vari-ND - by Singh-Ray.

The vari-ND allows the user to "dial-in" any desired level of light attenuation between two and eight f-stop's worth, simply by rotating a ribbed ring on the filter. Apart from the technical acumen required to make this work, by providing the photographer near instant control over a vast continuous range of effective exposures makes the vari-ND a truly remarkable device.

Well, I've had this magic filter - and it is magic! - for a few weeks, and had a chance to experiment "Seeing" with it; some examples of which you see sprinkled throughout this post. It works precisely as advertised, and is a lesson in elegant design and workmanship. There are two sizes - 77mm and 82 mm - which is not a problem for those (like me) with smaller sized lens, since you can always use a step-up ring to match the filter. Indeed, having a smaller lens is actually an advantage, since you reduce the possibility of vignetting at wider-angles.

Objectively speaking, the vari-ND does not provide anything that a photographer cannot achieve in other ways, using other tools. But oh how magnificently effortless vari-ND renders that work! If the possibility of creating lasting works of art depends, in even small measure, on the artist being unburdened from logistical/technical constraints, then - I say - the vari-ND is truly a magic filter! It is brilliant in conception, flawless in design, and produces stunning images.

If you are a seasoned photographer looking to expand your creative possibilities, have just started exploring the dynamics of light and exposure, or have ever wondered what it would be like to control up to 8 f-stops worth of light with a simple twist of a filter, go here, and order one of these magical devices for yourself. You won't regret it!

A philosophical postscript: I use the word "magic" in the title and in my reference to the vari-ND for two reasons. The first reason has already been hinted at in the text above, and has to do with how this filter "magically" renders effortless the willful imposition of desired exposure time (on a technical level). The second reason, unarticulated explicitly above, is decidedly philosophical. What this filter does, in effect, is to transform our normal, every-day perception of temporal flow - in which the world appears to move in localized snippets of time that last roughly 1/30 to 1/60sec - to glimpses of a supranormal, otherwordly, realm in which time moves at a slower, sometimes significantly slower, pace. It thereby also transforms us into temporally transcendent beings, that temporarily exist outside of time, and are able to marvel at time's own inner rhythms. Who is to say what is "real", and what is not? Is the "real" stream of water the one my eyes provide a visual imprint of?" Or is it the ethereal cloud of vapor that my "temporally transformed" eye glimpses, however briefly, with the aid of the vari-ND? Both are "real", but neither is definitively so, of course. Moreover, I would argue, it is this simple, but profound, realization that we have momentarily stepped "outside the normal flow of perceived time" - along with the even deeper realization that the clearest view of reality can only take place from some vantage point outside of it, on a meta-level - that points the way toward something approaching a "spiritual" enlightenment. Thus, the second reason I use the word "magic" in describing the vari-ND, is that it "magically" reveals a (normally hidden) spiritual realm.

Toward an Aesthetic Grammar: Part I

A few years ago, I gave an invited presentation at the Smithsonian Institute in Washington, DC, entitled Nature's Way: The Art of Seeing Complexity. My lecture was part of a multiweek workshop sponsored jointly by the Washington Center for Complexity & Public Policy and the Resident Associate Program of the Smithsonian Institution.

The ambitious goal I set out to accomplish with my talk - which, in hindsight I ought to have known would be impossible to achieve in the short time I had to achieve it (about two hours) - was to use the soul-searching inner musings of a physicist as photographer as a springboard toward forging a possible conceptual bridge between art and science; one that is defined by an aesthetic grammar, and hints at an even deeper aesthetic physics (two phrases that I promise to define more carefully below). As I diligently plowed through my slides, and talked through a few I had prepared especially to explain these subtle points, I could tell from the many blank stares and questioning smirks, that my skeletal new art-science "aesthetics theory" was destined to fall far short of my intended goal that day.
"The division of the perceived universe into parts and wholes is convenient and may be necessary, but no necessity determines how it shall be done." - Gregory Bateson (anthropologist, 1904 - 1980)
So, for another, slightly expanded attempt at communicating some soul-searching inner musings of a physicist as photographer...let me begin - in Part I of a multipart series of essays I intend posting in the coming weeks on the same topic as my Smithsonian talk, but retitled Towards an Aesthetic Grammar - by introducing a provocative theorem that I will first make a cautionary meta-claim about: please be forewarned that the theorem I am about to state will likely strike you either as obvious (at best) or idiotically vacuous (at worst). However, I will immediately argue that not only does the truth (of its interpretation) lie nowhere near these two extremes, but that the theorem is deceptively subtle and points to a universal "core truth" that underlies all cognitive, scientific and creative endeavors!

What is this remarkable theorem? It is called the "Ugly-Duck Theorem" (named after the well-known story by Hans Christian Andersen), and was proposed and proven by statistician Satosi Watanabe in 1969 (who was then at the University of Hawaii).

Suppose that the number of predicates that are simultaneously satisfied by two nonidentical objects of a system, A and B, is a fixed constant, P. The Ugly Duck theorem asserts that the number of predicates that are simultaneously satisfied by neither A nor B and the number of predicates that are satisfied by A but not by B are both also equal to P. While this assertion is easy to prove, and certainly appears innocuous at first glance - indeed, you would be forgiven to think it entirely "meaningless" since it is merely restating an obvious combinatorial fact about the set of possible predicates - it has rather significant philosophical and conceptual consequences.
"Thought is creating divisions out of itself and then saying that they are there naturally." - David Bohm
For example, suppose that there are only three objects in the world, arbitrarily labeled (@,@,#). An obvious interpretation is that this describes two kinds of objects: two @s and one #. But there are other ways of partitioning this set. For example, line them up explicitly this way: @ @ #. An implicit new organizing property seems to emerge: the leftmost @ and the rightmost # share the property that they are "not in the middle". We are free to label this property using the symbol @, and the property of being in the middle, #. Now, substituting the new property for each of the original objects, we have @ @ # -> @ # @.

Had we sorted these three objects according to the new property (that discriminates according to spatial position), we would again have two kinds of objects, but in this case they would have been different ones. Obviously, we can play this game repeatedly, since there are endless number of possible properties that can arbitrarily be called @ and #. That is the point. Unless there is an objective measure by which one set of properties can be distinguished from any of the others, there is no objective way to assert that any subset of objects is better than, or different from, any other.

The theorem demonstrates that there is no a priori objective way to ascribe a measure of similarity (or dissimilarity) between any two randomly chosen subsets of a given set. (Or, stated more whimsically, the theorem states that, all things being equal, an ugly duck is just as similar to a swan as two swans are to each other!) More technically speaking, we see that asymmetries within a system (i.e., differences) can be induced only either via some externally imposed “aesthetic” measure, or generated from within.


"Of course" ... you might be saying ... "that is obvious! But why is this important?" It is important because it demonstrates that - fundamentally - all of our perceptions of the world, precisely because they are demonstrably not all uniform, appear as sets of different things interrelated in a myriad of ways because of an internal aesthetic (or internal grammar, or physics!) that we automatically impose on what we perceive (doing so mostly unconsciously). The problem is to find a way to characterize and articulate what such a grammar might actually look like!


We "see" rocks and chairs and people primarily because nature has evolved an immeasurably powerful sensory-cognitive processing mechanism that rapidly "tags" for us (for our "I") the patterns in our environment that we will most likely be interacting with repeatedly throughout our lifetime. These objects are not visible to us (as "things") because the universe has labeled them "objectively meaningful" in a global sense (I doubt whether the universe really cares whether a particular transient pattern of atoms is called a "chair", a "collection of wooden planks" or "an exemplar of post-modern, neo-minimalist drivel"); rather, they appear to us as "meaningful" only because they are meaningful to us locally, in terms of the natural aesthetics we were born with (and evolve for ourselves as we interact with our perceptions and experiences) that determine what objects we can see, and the degree to which we can distinguish one object from another.

Who we are - our "I" - is defined and shaped most strongly by our internal aesthetic; which, I shall argue shortly, does not just describe "what we happen to think is beautiful at the moment" but molds our entire conception of the world, with all of the artistic, scientific, philosophical and spiritual depths that entails.

When I use the phrase "conceptual grammar" (or "aesthetic grammar") I mean - no more and no less - the set of aesthetic-weights we use (mostly unconsciously) to ascribe more or less "thingness" to an object A compared to another object B. According to the Ugly Duck theorem, we would expect the components of this set of weights to all be equal and therefore completely undiscerning in a rigorously objective world. Our conceptual grammar, understood in this way, therefore also constitutes the backbone of a primitive "local physics" we all use to describe our world; where by "physics" I mean a set of "organizing principles" that describe the underlying patterns of what our aesthetics "permit" us to recognize as existing.

Thus, when I write "grammar", I am thinking of primitive building blocks of "things" that (we imagine and/or perceive to) populate our (aesthetically generated asymmetric) local world, and the ways in which things may be "combined" to yield other things. And when I write "physics", I am thinking of the primitive building blocks of "patterns" that connect the things.
"Man tries to make for himself in the fashion that suits him best a simplified and intelligent picture of the world; he then tries to some extent to substitute this cosmos of his for the world of experiences, and thus to overcome it. This is what the painter, the poet, the speculative philosopher, and the natural scientist do, each in his own fashion." - Albert Einstein
I will discuss some important consequences of the Ugly Duck theorem, and suggest how it might be used to generalize what we (think we) know about our "scientific aesthetics" to begin probing what an (objectively artful) "aesthetic grammar" may look like, in Part II (stay tuned....) Speculations on what all of this has to do with complexity, photography, the "art of seeing", and using art to find one's "I", will also appear in forthcoming essays.

Technical Note: The Ugly Duck Theorem complements another well-known theorem called the No Free Lunch theorem, proven by Wolpert and Macready in 1996. The No Free Lunch theorem asserts that the performance of all search algorithms, when averaged over all possible cost functions (i.e., problems), is exactly the same. In other words, no search algorithm is better, or worse, on average than blind guessing. Algorithms must be tailored to specific problems, which therefore effectively serve as the external aesthetic by which certain algorithms are identified as being better than others. Technical proofs of Watanabe's theorem appear in his books Knowing and Guessing and Pattern Recognition (both of which are, sadly, out of print).

Appearance vs. Reality


The checkershadow illusion is one of the more remarkable "illusions" I've encountered, that goes to the heart of how we (as visual information processors) interpret and categorize the world; it also goes to the heart of the question, "Are you really sure of what you are looking at?"

Believe it or not, the squares marked A and B are exactly the same shade of gray! If you do not immediately believe your senses (as I suspect you won't!), just copy/save the image to a jpeg file and use any image processing program to sample the actual luminosity of each square...truly amazing!).

The "explanation" is that our visual systems require more than just luminosity to assess the shade of grey to be assigned; it also needs such features as local contrast and boundary effects. A complete explanation is provided here.

The checkshadow illusion was devised by Edward H. Adelson, Professor of Vision Science in the Dept. of Brain and Cognitive Sciences, Massachusetts Institute of Technology. His site includes many other startling illusions that explore the nature of perception and interpretation of reality (see his Illusions and Demos), as well as technical papers explaining his theories and findings. Adelson's site is a must-see for all photographers who "believe" they know all there is to know about appearance, reality, and the true nature of tonal gradations.

Additional references (and illusions) appear on the Perceptual Sciences Group homepage.

Space, Time, and Perception


The Hirshhorn Museum is currently exhibiting a career survey of Hiroshi Sugimoto (b. 1948, Tokyo), a master of using photography to explore the nature of space, time and perception. The exhibit runs between February 16, 2006 and May 14, 2006.

Sugimoto is known for his starkly minimalist, conceptual images of seascapes, movie theaters, natural history diaramas and architecture, that often border on the mystical. While, at one level, his images are "simple" (his seascapes for example sometimes offer little or no contrast between object and background at all!), at another, deeper level, they all compell the viewer to ponder such questions as "What is time?", "What is space?" and "What is real?"

According to the Hirshhorn site, the Smithsonian's Arthur M. Sackler Gallery will feature Hiroshi Sugimoto: History of History (from April 1, 2006 through July 30).

Here are two online galleries of some of Sugimoto's work (the first includes an interview with the photographer): Eyestorm & Robert Klein Gallery.

A generous sampling of his images (that require much time to slowly digest, emotionally, cognitively, and spiritually) appear in the book Hiroshi Sugamoto, by Kerry Brougher.
