Food for Thought about Photorealism

Wed Jun 14, 2006, 9:54 PM
Had a terribly interesting thought a moment ago, thought I'd share it with you and see what you think.

Wouldn't share all the following technobabble with you for its own sake, but its ultimate point seems potentially useful for any artist to think about.

This thought is the culmination of a subconscious path I've been on for years, but just now realized:

I don't think black is photorealistic.

Emphasis on the "I" there - it's an opinion - but ponder the magnitude of that while I explain myself...

And keep in mind I have no artistic training, so if I'm stating the obvious, please forgive me.


First off, for anyone unclear on my idea of "photorealism:"

Some people, justifiably, would ask, "how is it meaningful for a photographer to consider himself a photorealist?, when a (decent) photograph is photorealistic by definition?"

It's that the camera itself imposes a lack of reality, because by necessity it captures a more dramatic contrast that we see with our own two eyes. Our eyes adjust to changes in brightness so quickly that we can see much more dynamic range "on the spot" than a camera can often capture in a whole scene. (Have actually become sensitive to this optical quick adjustment in my own vision - it's kinda strange!)

My goal as a "photorealist," then, is to put the reality back into the photo, in effect making the tone (if not the color) more like we'd see with our own two eyes. (Honeymoon Is Over and End of the Tunnel being prime examples.) Think, emphasis on the "realist" rather than the "photo." And what I've been doing for years, long before ever thinking about this consciously, is spending much more care on my midtones than is common, besides which pulling in detail from my extremes.

I think it was quite accidental to begin with, driven by necessity - rich midtones hold color better - but then became a learned behavior once I got more obsessed with form, and eventually among my highest goals.

But this has been contrary to much of Photoshop tradition, which has tend to make contrast more dramatic than the captured shot. It's tend toward this for a number of reasons:

First, because higher contrast is simply more attention-getting optically;

Second, because higher contrast is frequently more iconic, reducing a subject to a more stark rendition and therefore more direct representation of itself, in effect "boiling out" the reality to portray something more directly conceptually (i.e., the "Charlie Brown everyman effect," but less extremely);

And third, because Photoshop's own commands favor expanding contrast, much more than they do compressing it without throwing away detail.


Have been especially aware of this latter point because of a recent tech leap, in which I create a "fillet" of a contrast, "chopping up" or pulling its brightest and darkest detail inward toward 50% grey but maintaining all suitable detail distinction. (As near as I can tell, it'd be impossible to do with a Curve, and certainly not to the same quality.)

This "pulling in," incidentally, without running High Pass (that I'm so obsessed with lately) or any other filters (cause I don't allow myself any others), so it offers many benefits of High Pass - bringing detail into a more even playing field - but with no halos whatsoever. (It then, in turn, becomes a fabulous basis for High Pass, but with tons of its own value regardless.)

(It's basically a counterintuitive blend operation, used twice subconsciously (in both Eye on the Prize and Promise to Keep) before noticing its significance. Used it quite consciously in Ever Since Forever After to restore form to his blown out face and the jacket from the shadows. It seems to offer benefits similar to superluminosity, which has been my shadow-detail/dark-hair godsend for nearly two years, but on both ends rather than just pulled up from shadows.)

And I have found this contrast a revelation to work with. That is, it creates a whole different basis on which to shape light and shadow. (Not to mention a whole different quality of edges.) Have long been theoretically intrigued with working "outward" from gray rather than up or down from an extreme, but lately have finally figured out how to make it practical.

(Ironically to this discussion, however, the fillet "pulls inward" all of a contrast except pure black and pure white, which it leaves alone. So it definitely benefits from a proper exposure to begin with. But the reclaimation of form from very-near-white and very-near-black is beyond belief.)

So as I've been experimenting with this, finessing the contrast back out, I keep noticing that when I push back out to some blackness is when I feel I've "gone too far." Am sceptical of pure white too, of course, for its loss of detail, but not nearly so much as I'm "threatened" by pure black.

In "the real world," there are things too bright to look at (and see detail), but virtually nothing (in lit conditions) too dark. It's amazing, if you notice, what we can discern out of even deep shadow.

Grasping this consciously just now inspired the thought.


Been having a good note exchange with =althepal99 (check him out!) ever since Eye on the Prize. All over the map about lots of things, but often about the nature of contrast itself.

I was 90% done with a reply today when it was time to leave work, but I was asserting a basic dilemma I struggle with:

1) I resist "higher contrast" as "too easy," but
2) I feel I should explore it artistically because of its inherit power, but
3) I run into a powerful mental roadblock every time I start to throw detail away, and I almost always "wuss out" from doing that.

(Life by the Horns and From This Day Forward being prominent exceptions, of course, and I don't mean it as an absolute anyway, but just a strong tendency. Cliches Because They're True was more typical, compulsive about not "throwing anything overboard." All the source detail is still there.)

But it was only just now during some research that I figured out where this "stall" is coming from:

Assuming a scene is lit (rather than unlit or nighttime), we don't generally see black with our own two eyes. We see some quality of detail or reflection once we both to look straight at it, rather than an empty vacuum of space. Even black things have texture, or shine.

And I feel like suddenly I understand so much of what I've been doing for ages, and so many values I've been striving for, even when I couldn't technologically achieve them yet. (Not until lately, when my new "silver lining" technique makes it easy to pull blacks into silver and then gently back into suitable shadow).

Was just drafting on a piece called Valentine Wishes. I spent over a hundred hours last year trying to pull off a certain "shiny photorealistic" look that constantly elude me, until I finally gave up in frustration. But, worth noting, more focused than ever on learning how to do what I then clearly didn't know how to do. That failure drove the year of research that's led up to the payoffs ever since (the Finishing Rinse, Silver Lining, the Fillet, which are all easy now, and Deep Depth, which is still a struggle but getting there).

Popped open Valentine Wishes' source shot and brewed up "the proper look" in about an hour. Which a hundred hours couldn't achieve before.

But it seems to "teeter over the line" as soon as I allow almost any true black.

(Not that it didn't have countless other problems last year, but "true black" may have been the last one.)


Have long been enamored of black and white film prints from the 50's and 60's. Not even necessarily "the real thing," but rather my conceptual memory of them: as silvery midtone renditions without a lot of bottom body to them. (I.e., the impression they've made on me has been more central to my thinking than the actual truth of that observation. I expect it's a drastic oversimplification to recall that era of photography that way. But, rightly or wrongly, it's what I remember most about it.)

For ages, if you'd asked me about my goals for digital photographic development, I would have point you back toward that ideal as represented in the film tradition. I'm purely digital, with no interest in actual film whatsoever, but terribly interested in those results. I've always know that was the kind of quality I was after.

So now I suddenly feel like a bunch of different threads in my thinking are coming together into a unified theory...

True black isn't photorealistic?

What do you think?

Never really thought about it that way before. You make a lot of good points though.

I guess my biggest thought is that as a photographer, simply trying to make a photo realistic image might keep some other artistic aspects out of the photo. I think all photographers try to enhance (whatever definition the artist has for enhance is) their photos, but simply trying to make visual eye candy might be to easy, or leave other options out of consideration. It makes sense that people like to up the contrast because, as you say, it's more attention-getting. But I never really thought about all the detail and textures in shadow areas that would normally be reduced to black.

Thanks for the thoughts.
:iconskizo:
Indeed. I find a similar problem in 3D drawings too. Pitch black (that would be RGB(0 0)) can't be considered a color to use at all. And the reason is simple: you can't modify it with anything. Even if you set a light straight up of the black object it wouldn't do anything because any number by 0 still results in 0 (and that's why I use RGB(1 1) for what matters...).
Because if you start to think about it, anything black you see, anytime, is lighted by some source of any kind. What my eyes see any time are tones slightly lighter than pure black, but NEVER pure black. Pure black after all is the color you see when you don't see.
So in this point of view, yes, "true black is not photorealistic".

Or so I think. :meditation:

"...how is it meaningful for a photographer to consider himself a photorealist?, when a (decent) photograph is photorealistic by definition?"...

"My goal as a "photorealist," then, is to put the reality back into the photo...more like we'd see with our own two eyes"

The term "heightened reality" comes to mind - close, but that's not quite it either.
Maybe "re-instilled reality" would be more apropos to your work.

Your second statement that I've quoted, really sums it up.

:iconrenilicious:
Oy... I think my brain just exploded. You keep doing that.

Considering I'm a fan of contrasty images with lots of tone ranging from stark white to pitch black, I actually do believe that the extremes of tone can be photo-realistic. Black is mainly used to hide something/one in an image. For me, photo-realism also includes an element of capturing the character of the subject as well as the overall image. Sometimes high contrast helps portray a more accurate character than what lower contrasting pictures would.

Then again, I suppose it's the perogative of the artist (trained or non) to make the audience see what they (the artist) sees or what they (the audience) wants to see and what each person's idea of photo-realism is.
:iconsurrealist-geek:
You're right - we very rarely see absolute black.

That truth is part of something much bigger, though. It's a small part of the fundamental reason why I was always terrible at drawing anything remotely realistic. My hand/eye coordination and such isn't brilliant, but it's adequate (as demonstrated by my Tylwyth Teg series, which unfortunately isn't available online). My main problem was that I drew what an object was, rather than what it looked like. I'm still learning to see the world as it looks before the brain processes it - I'm not planning to start drawing again until I get somewhere with that. Appropriately enough, my current equation art project is the precise reproduction of a photograph (I look on it mostly as a training exercise).

On a side note, you might be interested in the non-Dadaist part of surrealism: the idea that you can make something which looks more real than the real thing.

:iconmooseh:
If you look at it from the point of view that there is always some sort of reflection, otherwise our eye would not see it, then yes, you are quite correct.

But as you say yourself, most people enhance photos to be more eye catching or appropriate to a theme or what have you. And as such, most people don't seem to worry about it.

I agree with the concept of what you’re saying but it isn’t the black that I find myself concentrating on. As I stated many months ago photos shot with black and white film tend to have a much higher contrast than either color film or slides and most defiantly more than an image shot with a digital camera.

It seems to me that when I shoot these days I’m obsessed with the blues. I will examine the subject that I intend to shoot and its surrounding area. What I “see”, only because I look for it, are that over whelming blues that we normally over look and filter out. I realize that these blues will stand out and make the image look unnatural. As as you have said about the gray tones it is more photo realistic if the image were blue because the blue. I then adjust my white balance to allow for more reds that will warm the image and latter adjust it even more with Camera RAW for that perfect shot. The bottom line is that we all do this but when we shot do we simply correct the blues by adding more warmth when we open the image or do we really look at the subject and really see just how unflattering all that blue really is.

The long and the short of it is that unless we shot in the very early morning or late afternoon we will almost never upload, print or showoff a “photorealistic” image because they suck.

:iconsubversive-imaginati:
Well you do know that artists studying realism in oils/watercolor or any other traditional medium are frequently told not to use pure black don't you? That's because Black is not a color, it's a hue and it's flattens pictures frequently if used, some colleges tell them to use near black or extremely dark color hues ie very dark green instead. Some artists argue the opposite and insist on black's inclusion though, it depends on the artist.

The only pure black I ever use in an image is if I'm doing digital ink lines otherwise all my "blacks" are textured from various almost black shades.
