  • Over-processing

    Over-processing

    How much post-processing is too much? Is less better? Is there some magic boundary you shouldn’t cross? Over-processing is a controversial topic for many photographers.

    Purity

    Ah, purity, respecting reality, make no changes. This concept and value system is instilled into many photographers, especially landscape artists. I still follow Nature Photography Network. The images are often very lovely. But there is generally, to me, a sterility to them. Most photographers who post here are afraid of departing from literal reality.

    In this group, as in many landscape forums I have seen, there is a real negative feeling about cleaning up distractions, adjusting color to be anything other than the actual original, compositing, or anything else that is not strictly faithful to the original scene. It reminds me of some film photographers who used to make prints with the film rebate showing to prove the image was not cropped.

    The problem I have is the fear to depart from reality. Fear is not a good guide for art.

    What is photography?

    Is photography to be a literal recording of reality? Some people believe that it is. I used to be in this group, way back. As a matter of fact, the camera club I used to be a member of went further to say that a nature image must not show any “hand of man”. That is, there could not be a trail, a contrail, an old mine, anything not completely natural.

    But what is photography, really? I see it as an art medium. Composing interesting images from “real life” scenes in front of a camera is just as valid an art as painting scenes that exist only in the artist’s mind. Just as the painter only includes what is necessary to further the image, the photographer eliminates what is distracting, either in camera or in post processing. The goal and only real measure is the final image.

    In impressionism or modernism or post-modernism or any of the other isms, the artist freely pushes the medium to its limits to give his preferred interpretation of reality. And that, to me, is a key thing that makes it art – it is an artist’s interpretation of the world.

    What prevents photography from doing the same thing? A modern sensor can record a scene in very high resolution, and our software tools allow us to “correct” color and noise and other artifacts to a high degree., Does that mean it is the place of photography to create images that are constrained to faithfully depict reality?

    Is there a line you shouldn’t cross?

    Is there a line, a limit, not to cross? Probably, but it is different for each of us. As an artist, we need to be able to figure it our for our self.

    Our post-processing tools are amazing. They allow a level of control unheard of a few years ago. There is sage old advice, though, that says just because you can doesn’t mean you should. Anything can be misapplied to create garbage.

    It is easy to go to the computer and over-saturate and over-sharpen and re-mix colors in garish ways to make an image into something I would never show anyone. But that line where I have gone too far is personal to me. It would be different for you.

    Go for it

    As I mature, I find the line is moving our toward the horizon. That is, I am finding interesting ways to express my vision using post-processing “excesses”. Is my vision moving or am I learning to use the tools better? I don’t know for sure, but it is probably both. What we discover we can do influences the notions of what we want to do.

    The image with this article is a completely natural scene that has had what I would consider “moderate” post-processing. I like it much better than the bland original.

    These tools that can be used to create horrible garbage can also be used with great subtly and finesse. Like with a painter, the same paint and brushes can create a useless smear or a respected painting. It comes down to the artist’s vision and how the tools are used.

    Maybe asking if the image is over-processed is not the right question. Maybe the question is did the artist realize his vision? And did the vision resonate with me?

  • Ostranenie

    Ostranenie

    Say what? It is probably a word you have never heard. Ostranenie (good luck on the pronunciation) is a Russian word that refers to “defamiliarizing” scenes so we can see them new. I think it has application to art.

    Definition/history

    The term was created by the Russian writer and critic Viktor Shklovsky in 1917. He was originally referring to poetry as opposed to normal writing. His point was that poetic language was intentionally different from our normal language by being more difficult to understand. By being formal and different, it gives us a different perspective on the world.

    The concept was fairly influential in Europe for a time, known as Russian Formalism. It was picked up in various forms by other writers and playwrights. Even Freud referenced it in his notion of the uncanny.

    How it works

    The Russian Formalists maintained that habit is the enemy of art. Therefore the artist must force the reader (in their case) outside of their normal state of perception.

    The problem with this is that it ends up relying on shock value. But shock wears off and becomes a norm. Then it becomes a degenerate spiral because things have to become more and more extreme to provide shock. Just look at most Amazon Prime or Netflix productions.

    Displacement, alternate reality, removal of what is known – these can become pretty heavy-handed psychological manipulations.

    Application

    A slightly softer definition is “Defamiliarization or ostranenie is the artistic technique of presenting to audiences common things in an unfamiliar or strange way so they could gain new perspectives and see the world differently.” This is actionable and a reasonable artistic device.

    It is easy to see in literature. Science Fiction sets things in a different time or place or it creates environments that do not exist in our world. This lets them make observations about us from the outside. Fairy tales give us great insights on the real world by creating fictional situations. Plays, movies, and poems all do it to some extent.

    How about the visual arts? One artist I see doing this is Brooke Shaden. She creates dark and mysterious scenes to ask questions about our situation. I don’t necessarily resonate with her work, but I respect her artistic technique a lot. And she is a very good instructor. Catch some of her classes on Creative Live.

    Even a simple thing like very long exposures can be a form of this, because it changes what you normally see into something different. My friend Cole Thompson does this well. He sometimes uses long exposures to drastically change what you expect to see in the scene.

    As an unlikely example, black & white photography is kind of this. By removing all color from images our perception is dramatically changed. It is familiar, but unfamiliar. It is definitely a new perspective on the world.

    Personal

    In my own timid way, I like to do this sometimes. Black and white is one example. I am a closet B&W artist. I love it, even though most of my work is dramatically colorful. One of the things I love is its ability to present a new viewpoint on the familiar.

    Time exposures are another common process for me. I like its ability to change our perception of what is happening by shifting the time reference.

    Intentionally distorting a scene to change the way we see it is another technique I like. The image with this article is an example. This is a straight shot, no Photoshop magic. One day I was having lunch in a favorite restaurant a couple of blocks from my studio. I noticed that some of the old windows in this 100+ year old train station were very distorted. If I photographed through them at a certain angle it enhanced the distortion in desirable ways.

    This shot is a view of my downtown. The distortion reduces it to shapes and color while adding an intriguing texture. I like it. Luckily, the manager is a friend and didn’t mind me exploring to my heart’s content.

  • What’s the Noise?

    What’s the Noise?

    Noise in digital imaging. Is it a problem? Is it part of the art? Should you be concerned? Are there exotic techniques you need to learn to eliminate the noise?

    Fear

    Many of us have been taught to fear noise. So much so that I know people who would pass up a great shot because the image might be noisy. The fear of noise is an irrational, superstitious fear.

    This seems most common in the landscape photography community. Conventional wisdom, and the teaching of most instructors, says we should always shoot at the “native” ISO of the camera for lowest noise. That would be ISO 64 for my camera. If we don’t, we are increasing the noise in our images and that would be a “bad thing”.

    Have you ever examined the feared noise yourself? Do you understand what it is and what effect it has on prints? Have you confronted the monster and stared it down?

    Noise Technology

    The digital sensor is an amazing piece of technology. It has a HUGE grid of photo-receptive sites. My Z7 has nearly 46 million pixels. A strand of the smallest human hair would cover at least 14 of these pixels. No wonder I see dust spots!

    Did you know that “digital” imaging is actually an analog process? Each receptor “adds up” the number of photons it receives for a frame. This is a scalar value, an analog signal. Each site is read out to an amplifier and analog-to-digital converter where it is transformed into a digital value. The amplification is determined by the ISO setting – dialing in a greater sensitivity corresponds to more amplification. This amplification is one source of noise. Any time you take a very low level analog signal and amplify it, some noise is inescapable.

    But in addition, the sensor chip itself contributes noise. There is a phenomenon called “shot noise”. It is beyond my ability to explain simply, but electrons spontaneously generate noise. It is usually low level and it is temperature dependent. This is why your camera probably has a long exposure compensation mode. It is there to reduce this background noise accumulated over a long exposure. During a long exposure the sensor is powered for long enough to raise its temperature, leading to increased noise. The compensation mode takes another exposure, but with the shutter closed. This reads the background noise level with no light coming in. The camera basically subtracts the noise signal from the original image. It does a pretty good job.

    The amplifier and the sensor noise generation are 2 significant sources of noise in digital imaging. Not the only ones, but they are big. Keep in mind that most of the writers you will see do not have a significant technical background. They sometimes give bad advice because they do not really understand what is happeningl

    What does the dreaded noise look like?

    Take an image with the ISO cranked up pretty high, say 12,800. Look at it at 1-to-1 magnification in your editing software. You will see that it looks kind of like blotchy sandpaper. You are seeing the 2 primary types of digital noise: luminance noise and color noise.

    Luminance noise looks kind of like the grain we used to see in fast black and white film. Some people like it and it does add an interesting texture to some images. Color noise is the mottled color patches you may see at high magnification. I don’t know of anyone who likes that. Both of these types of noise can be compensated for significantly by your editing software, like Lightroom Classic.

    Let me point out that noise is just a part of the image capture. It is not something that, when they see it, the authorities kick you out of the gallery or revoke your artist’s certificate. You have an artist’s certificate, right? 🙂

    Noise Techniques

    Noise is part of the technology we deal with because we do digital imaging. We need to be aware of it and know how to deal with it, if it is a problem for us. I mentioned amplification noise and sensor noise.

    To minimize noise, keep the ISO low, keep the sensor cool, and minimize long exposures. Simple. But what if that doesn’t work?

    I will use me as an example. I often shoot in low light, sometimes hand held with no tripod. And I often use long exposures. Am I doomed?

    Here are the decisions I generally make: if I want the image to be free from blurring caused by shake, I up the ISO until the shutter speed is at about 3x the focal length. Yes, conventional wisdom is 2x, but I find that does not work well for very high resolution sensors, even with great image stabilization. If I want a long exposure for the creative effect, I use it. Noise is not a significant consideration most of the time. And, unconventionally, I usually leave the long exposure noise compensation off.

    Let me address that last one. Why would I leave the long exposure noise compensation off? The noise here is made worse by sensor heating. I shoot a lot in Colorado. Unless it is mid summer, the sensor stays pretty cool. As a matter of fact, it is often more of a problem keeping the battery warm enough to not shut off. And even in summer, it is not a problem to wait a few seconds between shots to let it cool. There have been a few times where I have gotten in trouble with this, but very few.

    So what?

    For me, noise is just a part of the creative balance. Sometimes I want to minimize it, sometimes I actually want to introduce it. Even for the vaunted landscapes, noise can introduce a welcome texture at times, maybe to give a grit for effect or to give subtle interest to a featureless sky.

    I do not fear noise. ISO 400 is my default setting – that is 3 stops over the camera native ISO. I do not mind going to 3200 or 6400 if I need to as a tradeoff to capture what I want.

    With my camera it is hard to discern noise at 400. There is not much to find at 1600. I admit, my old training to favor the lowest ISO sometimes interferes with my artistic judgment. I try to fight it.

    The image with this article was shot at ISO 6400, with what is, as of this writing, an 8 year old sensor. I’m not ashamed of the noise. It I didn’t shoot at 6400 I would not have gotten the image. Good tradeoff, to me.

    Noise is a traditional part of photography. It is a feature that sets it apart from painting. Black & White photography favored grain for a gritty look. Many artists like the effect. Even the ones who may not use it recognize and accept it as part of the medium. Digital noise is the equivalent.

    So don’t fear noise. Accept it. Use it where you can. Understand where it comes from and what control you have. Your editing tools have ways to reduce it, and they do a pretty good job. Luminence noise is not exactly the same thing as grain, but the overall effect is not that different. Perhaps always totally eliminating noise is not the goal. Did you ever see the slider in LIghtroom Classis in the Effects panel to increase grain? Play with it sometime. It may add to your artistic vision.

  • The Paint is Never Dry

    The Paint is Never Dry

    I find there are 2 categories of images in my library: ones I am “done” with and ones I want to tweak each time I open the file. Furthermore, it seems the ones I want to do something to each time I see them are the ones I like best. I refer to this as the paint being never dry.

    A significant advantage of digital image manipulation is that it is so easy to make changes. This can also be a problem.

    Wet paint

    Modern technology gives us great freedom to edit and express ourselves. It is so easy to make some changes every time we open the file. Oh, I didn’t see that little flaw. I really don’t like the relation of these tones now that I look at it again. Maybe it would have more punch if I pumped some of these colors some.

    But this is a subtle trap. A trap of time, because this is a never ending treadmill of editing, and of lack of confidence. I will write about this confidence problem in the future. Basically, it has been hard to accept that, as an artist, no one can tell me what is “right” or when I am “done”. I am the only one who can decide.

    Prints

    I wrote once about prints being a frozen moment in time. This is one of the great things about prints. They are not changeable.

    A print represents my interpretation of the image at one moment in time. It is very tempting for me to modify it a little every time I print it. But now that I do editions of prints, I have to discipline myself to create exact duplicates for each print in the edition. It would be dishonest and a disservice to the purchasers if each one was different.

    Part of the process of growth is deciding that an image is “done” and is ready to be shown and purchased . And I have to be able to stand proudly and represent it as my art, that I am proud of, even if I see opportunities for improvement.

    Creative vision

    But my creative vision is evolving all the time. It is frustrating to be locked in to printing a series a certain way when I may see it different now. I am resolved, though, that that is the requirement. I will have to exercise my creativity on new images.

    The images are my children, in a sense. But any parent finds out that after they grow up, you have to let them go. Send them on their way to be independent. I can no longer control them or manage them. Kind of the same with my images. When one is sold, the whole edition is frozen, out of my control.

    Oh, but the new images, the ones that haven’t sold yet. They are free to be interpreted and re-interpreted at will. I love to do this, but I recognize the need to let the paint dry at some point.

    As the artist, all my images are resources to me to use any way I wish. Even the editioned ones can be recycled by compositing, over-painting, or radical cropping. Anything that makes it into a whole new work of art. My creative vision can best be applied to new work rather than reworking old things.

    Growth

    I don’t believe doing a great image “uses me up”. I have to believe I have a boundless well of creativity. It is better to go out and create new work. Learn what I can from the best of what I have done and go on from there. Explore a theme and do variations. Discover new themes.

    My curiosity will lead me to new subjects, new visions for old ones, new points of view. I will learn new techniques for shooting and processing.

    It would be devastating to feel that my best work is already done. I would have to quit if that were the case. I feel sorry for the old rock bands who still tour. No one wants to hear their new work. They only want to hear the hits of 40 years ago. They are trapped. I couldn’t do it.

    So, yes, my tendency is to want to constantly rework and tweak everything. I often see things I would change in my work. But discipline has to be applied. Most old work should be left as a memory and a signpost along the way of my journey. Apply the creativity to the new images. Let the paint dry.

    A confession: even after writing all this about letting the paint dry, I went back and did some minor edits on the image with this article. This is an old image, scanned from film. The quality is not up to today’s standards. But I really like the feeling of the image and the memories it brings back of Chartres Cathedral in France. So I indulged myself in one more little tweak. Do what I say, not what I do.

  • Is It Interesting?

    Is It Interesting?

    I find myself pondering this question a lot these days. More and more I believe the answer to “is it interesting?” overrides many considerations of composition and technique. This is a personal judgment, of course. as is the question of what is interesting.

    Learning

    Art is almost as much about our training as it is about our natural creativity. We all start somewhere, whether we have formal training or we are self taught. When we are learning a skill or an art we concentrate on the mechanics first.

    The tendency is to focus our attention on what we are trying to master. This is natural. What we should recognize, though, is that we may not really be making art in the process. Yes, it is art in the sense that we create it as art, but it is not a mature and well rounded style yet.

    Technique

    Photography is possibly the most technical of the normal arts. We have to master many layers of technology to get skilled at the craft. There is the camera with its hundreds of settings and controls, each of which may help us make a great image or a terrible one. Then there is the computer system required to store and process the image. And the software we choose to use for managing and editing the image. If you are taking it all the way to the end of the chain, there is the whole printing process to learn.

    Each of these areas is a huge field that could require years of study to master.

    If this is where you are, plow into it. Work through the learning process. Get to the point where the camera is a comfortable tool that you can use with little thought. Ideally you should be able to adjust all the major setting in the dark, just by feel.

    The image processing software is probably an even bigger challenge. Photoshop is one of the deepest tools I have ever used, and that is from the point of view of a long career in very complex software development. There are only a few people in the world I know of who totally “know” Photoshop. Julianne Kost comes to mind, but then she is the chief Photoshop evangelist for Adobe. It is her full time job to be able to train people on any aspect of it. Others at about that level are Ben Willmore and Dave Cross. I study and use Photoshop hours a week but I will never get to their level.

    But the good thing is, I don’t have to be a Ben Willmore. As long as I know enough to realize my artistic vision, I’m OK. I know of excellent and successful photographers who I consider to have only a rudimentary knowledge of the tools. They know enough to do what they want to do. I personally can’t be happy unless I feel I have mastered my tools enough to comfortably use them as an extension of my creativity. So I study a lot. But that is just my own burden.

    It should be about creating interesting art, not our ability to use the tools.

    Composition

    The next major pillar of image making is composition. It is another thing that can become a lifelong study in itself. We can burrow into art history, visual theory, Gestalt psychology, and all manner of ideas and opinions.

    We start with only an intuitive feel for good composition, based on art we have seen and our inherent notions of what we like. Probably we cannot express in words what good composition is. As we study and practice we get to where we have a more formal view of it. We can critique our own or other images in terms of their design. Eventually, we can compose our images intuitively, without much conscious thought. We can repeatedly produce compositions that please us.

    Keep in mind that most of this time, we are producing images that are now technically “correct” and have “good” composition. But maybe nobody wants to look at them yet.

    Is it interesting?

    This idea was clarified for me in a book about poetry. (Writing Poems, Robert Wallace. The link is for a later edition of the book) Weird, huh? It is a book about writing poetry rather than a regular book of poems. I find hints and ideas to improve and better understand my art from all sorts of diverse sources.

    The author made the statement that if the poem is not interesting, what good is it? It can have wonderful form, metaphor, irony, symbolism, etc., but if it is not interesting, no one will read it.

    I believe there is something here to apply to our art.

    I have seen, and made, too many technically perfect, classically composed images of … nothing memorable. While I value sharp, well executed images, and pleasing compositions with flow and leading lines and great light, I have come to realize that is not enough by itself to really be art. This is, of course, just my personal opinion. But then all art is a personal opinion. 🙂

    When you have mastered the basics I suggest you first visualize something that will make a memorable image. Then use your acquired skill to capture it perfectly. Don’t just work on technique. You’re better than that.
