  • They Told You Wrong About ISO

    They Told You Wrong About ISO

    Many of us have a wrong idea about ISO settings. I will just say they told you wrong about ISO. It was a misunderstanding. Whoever “they” are.

    Statement of faith

    It is stated as a “strong suggestion“, especially when we are learning landscape or portrait work. Never shoot with ISO over 100. Maybe it is stated as only shoot at the native ISO setting for your camera. Either way, these are given as rules.

    I hate rules, especially for my art. Rule of thirds. Rules of composition. Never put the subject in the center. Never shoot at midday. Always use a tripod. The list goes on.

    Like with religion, most of the so-called rules are based on good ideas, but over time they are repeated as commands and the underlying reasons are lost. Just do it. (I don’t think that is what Nike meant.) The rules become a statement of blind faith that cannot be challenged.

    What is noise?

    All digital cameras have noise. Noise is randomly generated in the sensor and in the electronics of the signal path until the pixels have been digitized by the analog to digital converter (ADC). The noise is a fundamental property of physics.

    The question is how much noise is there relative to the desired data. This is called signal to noise ratio in engineering. When we amplify a signal by increasing the ISO setting, all the signal including the noise is increased. This is why images shot at high ISO settings tend to look noisy. The image is usually not less sharp, but there is more noise obscuring things.

    It is true for a low cost point and shoot camera or a high end medium format camera. What changes are the relative amounts of noise and the limits the image can be pushed to.

    What is ISO?

    You’re familiar with the exposure triad: the combination of aperture, shutter speed, and ISO that determine exposure. That’s it. Many other things affect the composition and quality of an image, but only those 3 control the exposure.

    Aperture is the size of the diaphragm opening in the lens. It controls, among other things, the amount of light coming in. Shutter speed is the length of time the shutter is open to let light come in. And the ISO setting is kind of like a volume control. It sets the gain or amount of amplification of the sensor data.

    Going way back to early film days, there were no agreed on standards for the measure of how sensitive film was. So a couple of the largest standards organizations (the ASA and DIN scales) came together and created a standards group under the International Organization of Standards. They adopted the acronym of the standards organization (in English) as the name. By the way, officially “ISO” is not an acronym, it is a word, pronounced eye-so.

    Long way around, but now there are defined standards for exposure. For a given combination of aperture and shutter speed, the ISO settings on all cameras give the same exposure.

    Why use higher ISO settings

    OK then, in concept, the ISO setting is a volume control for exposure. Turning it up (increasing the ISO value) amplifies the exposure data. But as I mentioned, it is not free. Amplifying the exposure also amplifies the noise in it.

    It is true that low ISO settings produce less noise in the captured image. Modern sensors are much better than early ones. This is one of the wonders of engineering improvements that happen as a technology matures.

    Then, we should not use high ISO settings, right? Well, everything is a tradeoff. We need to use a minimum shutter speed to avoid camera shake when hand holding or to stop subject movement. We need to use a certain aperture to give the depth of field we want. These decisions must be balanced in the exposure triad, often by increasing the ISO.

    Can’t I just underexpose?

    When you accept that we must use the lowest ISO setting, the logical conclusion is that you could massively underexpose the image and “correct” it in post processing. Unfortunately this doesn’t work well. You are still boosting the noise unacceptably.

    The camera manufacturer knows more about it’s sensors than your image processing software does. The camera’s built-in ISO amplification can take into account it’s characteristics and do a better job. And modern sensors and electronics do a very good job.

    Are you wrong about ISO?

    If you are following a rule dictating you must or can’t do something, yes you are wrong. There are no rules in art. No ISO-like standards body specifies what your image must look like. There are always groups wanting to do this (are you listening camera clubs?), but they have no authority.

    If you are hand holding a shot, it is better to boost the ISO to steady the movement than follow a rule about using low ISO. The noise will be secondary to the reduced shake. Or I sometimes use the lowest ISO setting in my camera to create blur. I enjoy intentional camera movement (ICM) shots and will occasionally force an artificially slow shutter speed.

    If it is night and you want to shoot stars or street scenes, are you not going to do it because you would have to violate a rule by the ISO police?

    Use the ISO setting that lets you express what you want to do. It is your art. There are no rules. Besides, luminance noise looks like film grain. It can be an interesting artistic technique in itself. Do what feels right to you.

    Apology

    I used fairly strong language about this. The reality is that most photography writers have softened their recommendations on ISO. Most of them freely recommend using high ISO. This is healthy.

    But I know many of us were “imprinted” by early mentors who left us feeling there was something dirty about going above 100 ISO. I want to free you if you still have those self-imposed limits. Using even a very high ISO and getting the shot is always better than missing it because you wouldn’t want to chance increased noise.

    Today’s image

    Since I’m advocating it, here is an extreme case that I’m happy with. This was shot hand held with an old Nikon D5500 camera – at ISO 22800. I have corrected out some of the luminance and chromance noise and I am perfectly OK with what remains. Getting the shot made me happy, even if the noise is high.

  • How Not to be Creative

    How Not to be Creative

    You can find suggestions everywhere about how to be creative. I decided to turn it around and offer suggestions on how not to be creative. Is that creative? 🙂 I can’t guarantee that doing the opposite will make you creative, but perhaps they may be warning signs for consideration.

    Creativity

    We all want to be creative (I hope). But what it is? How do you define it?

    We all have different views and expectations. For photography, maybe it comes down to making images that seem fresh and “different” in a good way. They say that everything has been photographed. I don’t buy that. But even if it has, there are new viewpoints or treatments or lighting on our subjects. And there are still lots of things no one has thought to photograph.

    Few of us will create wholly new art genres the world has never seen. Few of us really want to. But we can do work that people look at, come back to, and admire as a whole new way of seeing a subject. We can project our feelings onto the print, giving it our unique stamp.

    We often use the metaphor of the muse inspiring us to creativity. If the muse is with us we are creative. If she is not, we can’t seem to do fresh work. Yes, our creative inspiration seems to come and go; to have highs and lows. I do not believe some imaginary Greek goddesses actually have anything to do with it. It is really happening within us.

    So rather than chasing after creativity, I want to look at ways to stifle the creativity we have.

    Distraction

    If you live in the Western world, you are probably paralyzed by distractions. Our devices and entertainment rather successfully compete for all of our time and mental bandwidth.

    People open their phones dozens of times a day because of fear of missing out (FOMO). We are expected to be online and available to our employers 24/7, even when on vacation. The wonders of the internet has opened up far too many “opportunities” to spend our time and attention.

    But rather than being an incredibly empowering technological aid to us, it has become the master we are slaves to. People are online at work all day then spend many hours at home doom scrolling funny cat videos or new dance moves or movies we don’t really care about.

    So, a great way to subvert your creativity is to be so distracted we do not have time for original thought. Creativity requires quiet time and very limited distractions. In general, the more attention we give our phones and other devices, the less opportunity to be creative we have.

    The technology is not bad in itself. I have 1G fiber and i would not want to let go of it. What we do with it is where we can hurt ourselves.

    Stress

    Another great creativity killer is stress. Stress focuses all of our attention on the problems we are facing.

    The world always tries to keep us treading water. Just a couple of days ago my fuel pump went out, while we were driving in a hard to access location in the mountains. Do you know how long it takes and what it costs to get your car towed over Trail Ridge Road in Rocky Mountain National Park? And do you know what it costs to replace a fuel pump? That can peak your blood pressure.

    That’s just one little example. All of us deal with many sources of stress all the time. It comes with life.

    Like our devices, stress occupies all of our attention if we let it. When we are stressed and worrying, we are seldom thinking creative thoughts. It seems more survival mode.

    So, to kill creativity, give in to worrying about stress. Fixate on those problems. Live with a survival mentality.

    Of course, we can’t just wish our stressors away. We need to deal with them. How we deal with them is up to us. Attitude is a big deal.

    Trying too hard

    Want to chase away the muse? Trying too hard is a good way.

    We should always be trying hard. What I mean, though, is trying to force our self to create something on our schedule. Just sitting there saying “I have to create something; now; do it; right now”. How does that work for you?

    Maybe it works better for you than it does for me. If I try to force myself to be creative it seems to have the opposite effect. I am a total blank.

    Actually, I can often lure creativity to visit me by ignoring it and thinking about or working on something else. I believe artistic creativity comes from the subconscious. Our minds need to be occupied with something not too demanding so our subconscious can be free to wander and think new thoughts. But then we must be conscious enough to realize what just happened and capture the idea.

    Too busy

    Another good way to not be creative is to be too busy. Busy with demanding tasks that occupy all our attention and mental bandwidth.

    The world around us encourages a high level of busyness. What do you say when someone greets you? “How ‘ya doing?” “Man, I’m staying really busy!” It’s almost a badge of honor.

    Being busy is much better than being idle. But like most things, when taken to an extreme, it can be destructive.

    If you are one of those super busy people with a full calendar, how do you find time to be creative? Maybe it is as simple as doing some prioritization and putting some blocks of time in your calendar where you will let your mind relax and give yourself the space to focus on your art.

    Imitation

    The last creativity killer I want to talk about is imitation. Are you trying to make art like your mentor or favorite artist?

    I believe this is a trap because we cannot be them. We can make work that looks a lot like theirs. But this is looking backward at what they have done in the past. We cannot be in their mind and have the same thoughts and influences that will guide them to new work. So all we can really do is copy them. That is not creative. We are not adding anything new.

    Can we learn from other artists? Of course! That is how advancements are made. The critic Lionel Trilling is quoted as saying “Immature artists imitate. Mature artists steal.” Many others have said similar things in slightly different ways. The consistent point made is that we take what we can learn from others and add it to our own art. Just imitating them, though, is a dead end.

    Conclusion

    Creativity is something we all have in varying amounts. It is an enabler and motivation of being an artist. But we are surrounded by many powerful forces that want to stifle our creativity.

    All the creativity sucking problems I list here are real and probably attack most of us most days. They are easy to identify but very hard to overcome.

    We cannot just pretend they are not there. Instead, we have to be very aware of them and actively work to fight them. If we don’t, we will be sucked into their trap and our art will never be seen. The path of least resistance is to give in and let our creativity be choked out.

    Fight!

  • Color Perfection

    Color Perfection

    At the risk of sabotaging potential sponsorships from the color matching industry, I suggest some of us obsess too much about color. There is a difference between color perfection and color correction and color as an artistic decision and color as one of the processes we deal with. Know why you are doing it.

    Obsession

    Photographers seem to be obsessive about a lot of things. Color is only one of them. But we have color equipment manufacturers (arms merchants?) and blogs and videos constantly preaching to us that we must have a perfect color matched system from our camera to the final print or our work is amateur.

    This all sounds logical and authoritative, so we buy into it. And it can get expensive.

    So we buy colorimeters and special color corrected monitors. We make sure we have proper profiles for the printer and paper combinations we use. We even buy special systems to color profile our cameras.

    Now we can be confident that our wildflower picture exactly matches the colors of the flowers in the wild.

    Why?

    Why are we going to all this trouble? Does it really matter so much?

    Maybe, maybe not. It depends on your needs and values.

    All the steps to color correct your workflow are generally good. But unless you are doing product photography, it may not matter as much as you have been told. A corporation cares very much that the company logo exactly matches it’s color standards and that their official color pallet is correctly used.

    But if you are shooting landscapes, is it critical that the color of that leaf is the exact match of the leaf you shot? Or is it more important to match your memory and your preferences?

    My attitude

    I am not a purist about this. Actually, I am less and less a purist about anything as I evolve in my style. Any work I do is an artistic interpretation. I have no problem with changing colors if it gives me a more pleasing image. More pleasing means I like it. It has nothing to do with the match to the original scene.

    But I do it deliberately and intelligently. To do that, it is necessary to have control over your color process. And without a controlled color process your results are not repeatable. What comes out of your printer is likely to be wildly different from what you see on your monitor and different from session to session.

    That is chaos. You cannot reliably create your art. It is unprofessional and unsatisfying.

    But you need to have a color managed work flow

    It is important to color manage your workflow. That is not the same thing as obsessing about color perfection.

    Every month I calibrate my monitor with my trusty old obsolete i1 Display Pro colorimeter. And I print using proper profiles for my paper and printer. This gives me pretty repeatable colors. The biggest problem is keeping my monitor brightness low enough to match the prints.

    So far I do not find it necessary to profile my camera. Since I only shoot RAW, I can “re-profile” the images at will. And Lightroom Classic’s Camera Landscape profile is usually a good start for most of my work. Now days there are lots of profiles to try out to get a color starting pointl

    Overall, the biggest problem I have is dealing with printer gamut issues. Some of my work is highly saturated. It is disappointing when these images do not look as good as what I see on my monitor.

    Black & white

    The outlier in many parts of photography is black & white. Is it important to color manage black & white images? It seems wrong, but I would say yes, it is. It may be more important than in images that will stay in color.

    In color images, we look at the color, obviously. We tend to be pretty tolerant in what we accept as reasonable. But in black & white we only see the color indirectly through the tone relationships of the print.

    The colors are mapped to monochrome tones and shades. This makes it important to precisely control the color relationships to give separation of the tones. We may need to distinguish between fine shades of green, for instance, to give body to the b&w print. More than if the print were in color.

    What I do to the color may look strange if you saw it in color, but the important thing is the precise control required. This makes me believe color precision is more important in b&w than in much color work.

    Conclusion

    Have I confused you? I seem to have said color perfections is not important but you have to have a good color balanced workflow. Yes, that is right. Learn to live with ambiguity. 🙂

    My work is art. Everything is an interpretation of what I saw or felt. I usually do not care if the colors are “true”. They often intentionally are not.

    But it is very important to me to control and repeatably achieve the results I want in the final print. This requires understanding how to color balance my process and how to use it to achieve my vision.

    For me, color control is part of a repeatable process, not a commitment to absolutely match a scene.

    Today’s image

    This is Texas wildflowers in the spring. They really are like this, and in great bands over much of the state. Go there in the spring sometime. Spring in Texas wildflower country is about mid March through mid April.

    This is an accurate representation of what you will remember when you are there and see them. Is it totally accurate color? Probably not. Don’t know; don’t care. If you’ve been there, you will say “Yes! That’s what they look like!”.

  • Sustainability

    Sustainability

    Sustainability is a common buzz word these days. It is applied to everything. Every company and product claims it. For this, I’m going to redefine sustainability from an artistic point of view.

    Creative sustainability

    As artists, we live on our creativity. Do you worry that the well may dry up? What if your creativity goes away?

    If we produce hard, do we use it up? Or is the engine somehow fed by using more? Is creativity a “sustainable” resource or does it get used up?

    Since this is the core of what we do as artists, it is natural to worry about it. Probably all of us at some point have concerns that we may use it up. What would we do then?

    So, an ongoing concern for many of us is, should we ration and conserve our creativity so we don’t use it up? Is it even possible to conserve it?

    Sustainable creativity

    I don’t believe creativity actually gets used up. It is like a good well that always seems to be full when we need it. If anything, creativity thrives on being challenged and used. It seems like the more we call on it, the more there is.

    But is it sustainable? I think so, but we can be our own worst enemies. If we keep doing the same stuff over and over we get less creative. When we try to stay in a safe rut, there is less need to exercise creative. We’ve done it all. Many times. It is a major challenge to apply new creativity to repeating the same things.

    Unless we are following the lead of where our creativity wants to take us, we risk getting stale. When that happens, we seriously fear we are not creative any more. And we are right.

    That doesn’t mean our creativity is gone. But if we do not give it free rein to take us in new directions, it stops challenging us. For all practical purposes, our creativity is them used up.

    Creativity is like a good friend. It will be there for us, but we have a responsibility to nurture the relationship. If we ignore it, if we do not make time for it, it will eventually give up on us.

    Burnout

    Everyone goes through cycles. Creativity, and everything else in life, can ebb and flow. That is natural. But burnout is an extreme. It is a depressed state where it can seem impossible to ever again do the quality of work we want to do. It can persist for months or years if we let it.

    I know. I have been there. There was a time in my career when I worked long hours for years in a job that was not fulfilling. It caught up to me. I crashed. I pulled back, working less hours and not being as satisfied with the quality of my work. Eventually, by changing position and increasing the creativity of my role, I became productive and happy in my job again. It was probably a 3 year process.

    In burnout, it seems evident that creativity must be unsustainable. That’s not true, though. It is not creativity that lets us down, it is the other parts of our context. It is important to manage our lives and environment if we want to stay creative.

    Creative stimulus

    Like an athlete trains constantly, we must exercise our creativity to stay on top of our game. Everyone’s needs are different, so it is impossible to lay out a plan for you to follow to do it. You have to figure that out for yourself.

    I can provide some creative stimulants I have seen and used. Consider them. Try the ones that seem to fit you. Develop your own methods.

    I will just bullet point some of them. Each could be a topic on it’s own.

    Read. And not just the same old stuff. Read new things. Read things by people you disagree with. And also read some light stuff just for fun.

    Study something new. Don’t plan to get a PhD in it. Just learn something about it. If you like it, go deeper. If not, try something else.

    Write

    Go back and review your old work. Put together a new portfolio.

    Go to a museum.

    Travel to a new place that is NOT a major iconic photo location.

    Put blocks of time in your calendar to do nothing. Turn off your phone. Let your mind wander. Doodle. Look around. Intentionally be unproductive.

    Spend time with friends, just living life.

    Take your significant other out for a nice and unexpected meal.

    Find things that make you happy, but that are not just entertainment. Try to do more of them.

    Take walks, with and without your camera.

    Just do it

    The theme here is to fill your mind with new information. This connects in strange and unexpected ways, leading to who knows what. And to give yourself space and time to just think, ponder, consider, unwind. The more pressure we put ourselves under, the more it shuts down creativity.

    And like the inspired Nike tag line, “just do it”. Get out and work. Take pictures, Don’t worry so much about the results. Going through the motions is comforting and leads to results. Eventually. Creativity is not just inspiration, it is a process.

    Relax and try to de-clutter your head. Follow your instincts.

    Is creativity sustainable? I would say definitely. It is one of the most important traits we have as artists. We can consciously take actions to keep our creativity healthy and flowing. But we have to listen to ourselves and recognize what our needs are.

  • It’s OK to be Uncomfortable

    It’s OK to be Uncomfortable

    I recently read an article from a photographer who admitted he sometimes doesn’t stop to take a picture he wanted because he was afraid of what people would think. I understand that. I have been there many times. But I have come to the conclusion that it’s OK to be uncomfortable.

    What will people think?

    You’ve probably been here. I know I have. You are driving down a crowded road and you see a scene you want to photograph. But we decide not to pull off and get out the equipment because we would look foolish standing there beside the road taking a picture. All those people going by would think we’re weird.

    The reality I have learned, though, is that no one thinks about you as much as you do. That is a fact. We overestimate our importance. We will be more free and inventive if we stop worrying about what they may think.

    People go about their dreary lives almost totally focused on themselves and their needs. If they do momentarily notice you, even if they criticize you, you do not know what they are really thinking. Most often, they are responding to something in themselves. Because they do not really care about you.

    I love this quote from Susan Sontag: I envy paranoids; they actually feel people are paying attention to them.

    And from Olin Miller: You probably wouldn’t worry about what people think of you if you could know how seldom they do!

    If that random person driving by thinks you are doing something foolish, so what? How did that affect you? Did you feel it? Did it hurt? No. You do not know what they are thinking and besides, you are doing your art, not theirs.

    The anxiety we feel is internally generated.

    Attract attention

    I understand. I’m very introverted and I am uncomfortable attracting attention. An interesting dynamic because of where I live is that I do attract unwanted attention sometimes.

    In my area there is a lot of wildlife, such as elk, deer, moose, bear, mountain lion, bighorn sheep, pronghorn, etc. I guess I am missing the right genes, but I have little interest in them, other than to observe them. I almost never take wildlife pictures. But if I am setting up to take a picture beside a road, it is not unusual for people to pull off and eagerly ask me what I see. They seem so disappointed when I point to a tree. It’s actually kind of funny.

    And for the occasional street photography I do, I am one of those people who wants to be totally anonymous, unseen. It is uncomfortable when someone “catches” me taking their picture.

    They won’t like me

    So what do I do about this fear that people will think badly about me when I’m out shooting? The right answer is, ignore them. Easier said than done, but that is true of much of life.

    I have learned to try to put them out of my mind completely and get in the zone focusing on setting up the shot I want. Generally this works. Replace the negative concern of fear with the positive action of taking a picture.

    But even if it doesn’t work, more and more I come to the realization that I don’t care what they think. I am not trying to get them to like me or post a Facebook note about how much they admire that photographer they just passed. I don’t care.

    The results I get in these situations validates and justifies my callous “don’t care” attitude toward them.

    What are they going to do to you

    Let’s say some of the passing people give you enough attention to say to themselves “that’s dumb”. So what? What happened? Did you feel it? Did they throw a rotten tomato at you? Did they stop to get your name and take a picture of you to post on Facebook to shame you?

    Of course not. Absolutely nothing happened. They went on down the road and immediately forgot about you. If they were stopped 20 miles later and asked, they probably wouldn’t remember someone standing beside the road taking a picture.

    This is the quandary: we fear what people might think, but the reality is they don’t bother to think about us. And even if they did, it has no effect on us.

    Do what you need to do

    If you do what other people do, you get the results that other people get. – Bill Miller

    We are artists. We see things differently. That means we do things differently. Other people cannot know what our vision is at any moment unless we tell them or show them. Showing them is typically what we do.

    So do what you need to do to make your art. Do not be concerned about what anyone may think about you. First, they probably don’t. Second, it doesn’t matter. You have art to do.

    If you were embarrassed taking the picture feel doubly joyful when you see the great result. You can say to those people passing by who you imagined felt you were silly, “see what you missed”!

    Get over it

    I hope I have encouraged you to forget about your fear of people’s opinion and go for your art. Art is action. It is only an idea unless we create something.

    Act while you feel fear rather than waiting until you feel unafraid. – David Richo, in How to be an Adult

    How sad it is to think about what could have been a great image, except we were too embarrassed to stop and take it. I have done it both ways. I have passed by and regretted it and I have overcome my fear and stopped and usually been happy I did.

    I am old and calloused enough to believe now that I shouldn’t be overly concerned about what I think other people may be thinking. It’s OK to be uncomfortable. If being uncomfortable is a price for making our art, that is what we have to do.

    Courage is resistance to fear, mastery of fear – not absence of fear. – Anon

    To you who have never been intimidated by other people’s opinions, congratulations! You have a talent most of us do not have. Use it well. Don’t be an ass.

    Today’s image

    Do you like this image of the vast Utah plains? I do. It is not a result of trekking hours across the barren desert, watching for rattlesnakes. I took it in a rest stop on I-70, right next to the restrooms. It felt uncomfortable at the time, but I loved the scene and had to take it. At this point, I don’t recall the discomfort. But I still like the image.

    When you see something you like, stop and take it, unless it is dangerous or you have higher priorities at the moment, like a critical appointment. There are some things more important than our art. Not many, but don’t ignore them.
