$Diffraction$
Diffraction
Today I would like to try to help us understand a little about what diffraction is. Not getting too deep in the theory. Just enough to demystify it a bit.
Scary
Diffraction is probably a scary word to most of us. Even if we don’t know what it really means, we have heard of it and have been taught that it is a “bad thing”.
Have you been taught to avoid using apertures smaller than f/11? Note that when I say a “small” aperture I am referring to the physical size. Remember that as the aperture numbers get bigger the actual opening in the lens gets smaller. This simple graphic illustrates that:
The lore is that very small apertures (large f-numbers, like f/22) make an image too blurry to be useful. Don’t believe everything you hear without testing it.
Light theory
I’m going very light on theory (yes, pun intended). We’re just going to graze the surface without taking a deep dive in. (Here is a source to start at if you want to go deeper. Abandon all hope ye who enter…)
Light behaves as waves (most of the time). Actually, a number of things are waves: light, water waves, sound waves, gravity waves. Quantum mechanics theorizes that even matter is waves. Too deep for me.
We tend to visualize light going through our lens as rays. That is, straight lines. Yes and no. That is one useful model of looking at it. But light also behaves as waves. An interesting and important property of waves is that every point on a wave is a wave. So if the wave is blocked by a small opening, the wave spreads on the other side of the opening.
This picture by Verbcatcher does a marvelous job of illustrating that for waves in water:
$Diffraction in water waves$
See how the waves spread after going through the small opening to the sea? The smaller the opening (aperture) the more pronounced the effect. That is, a small aperture opening causes waves to spread out more.
What does it really mean
This is the basis of the recommendation to use physically large apertures (small f-numbers). Apertures that are large relative to the wavelengths of light do not cause much “bend” of the waves. Small apertures (large f-numbers) “bend” the light more.
What we can actually see in practice is that using small apertures causes our images to have a mildly “fuzzy” look. Because the waves spread more after going through a small aperture, the individual waves cover a larger pixel area. This slight spreading of the light causes the image to appear less sharp.
The best discussion of diffraction for photographers I have found is from this article by Spencer Cox. But even this gets too deep into theory.
I borrowed this image from it to illustrate the practical effects of diffraction as we change aperture:
$Effects of diffraction with aperture$
See how the larger apertures (small f-numbers) are sharper than the smaller ones?
This illustration below, also from Spencer Cox) gives a great conceptual representation of what is happening. Take that the grid represents pixels in your sensor. At f/4, the point of light only strikes one pixel. It will be seen as very sharp. But at small apertures, the waves spread some onto adjacent pixels and create a kind of fog.
Should you fear it?
Should you fear it and always shun small apertures? No, it is just a reality of physics. It is no more to be feared than gravity. As one of my sons would say, it is what it is. Be aware of what is going to happen and consciously decide how far you need to go.
All of the exposure determinations we make daily are tradeoffs. How much to stop motion? How much depth of field do we need? Is there enough light for a good exposure? What ISO setting should I use? All of these things and more have to be balanced in the moment of shooting, besides composition and esthetic issues.
Each setting costs something. As experienced photographers we must understand the tradeoffs and be able to judge what is right for us at the moment.
Diffraction is one of those tradeoffs. Know what it is going to do and how to use it or avoid it.
Sometimes you need more
But why would we ever intentionally make our image less sharp? We seldom actually choose to make it less sharp, but sometimes we need other things. I can give 2 easy examples.
The first and most common one is to increase depth of field (DOF). It is counter intuitive, but making the aperture smaller increases the perceived depth of field. So on the one hand we are making the image less sharp, but on the other hand we are making it appear sharper throughout. When we need to make a certain range of the field of view acceptably sharp we stop down the aperture until we achieve our goal. A tradeoff.

The second case that comes to mind is to reduce the shutter speed. I often intentionally shoot motion blur. But I usually forget to bring a neutral density filter for the lens I am using at the time. I can generally achieve the effect I want by using my polarizer, reducing the ISO to the lowest setting, and cranking the aperture down to the smallest possible one. This will probably give me a shutter speed in the range I want to use. Yes, the small aperture increases diffraction and makes the image less sharp. But it is handheld at a long shutter speed. It is already intentionally blurred.

But maybe more importantly, in a great video on Lumminous Landscape, Charles Cramer said “sharpness is something we have to get over.” He explained that if we take a picture just because it is sharp, it probably won’t be very interesting. We have to forget about how sharp is it and instead react to the scene before us on an emotional level.
Shoot the picture
Diffraction is a side effect of physics and our photographic technology. Don’t be afraid of it. Don’t blindly follow some rule you learned in the past about what you can or can’t do. Understand enough about it to recognize it and know how to use it to your advantage.
Look at the image above of the woman’s face. Even at f/32 – an extreme case – it is acceptable. Extra sharpening can be applied in your editing tool to compensate for it.
So diffraction is just there. Allow it to happen if that is the tradeoff you need to make. Just like using a high ISO adds noise, that is acceptable most of the time and better than missing the shot.
I know many of us don’t want to deal with what we perceive as increased complexity or too much technical detail. We just want to go take great pictures. My hope is that topics like this will actually make your photography life simpler by providing some grounding for information you may have heard in the past. Rather than trying to remember rules for how to use your equipment, you now have a model for what diffraction is doing and how strong its effect is. I hope you will be able to stop fearing it and accept it is just part of the tradeoffs of the technology.
Today’s image
This is a great old WWII era truck I found in my town. It is a Coleman. This was actually a Colorado company. It was designed and manufactured in the Denver area.
I needed enough depth of field to span from the great rust and paint patterns on the near outside through most of the cab. So it is shot at f/22. Diffraction? Works for me.
What do you think?

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.

The Histogram is Just Data
I don’t mean to be insulting, but I cannot understand when people look at histograms as some magical, mysterious, and intimidating technical artifact. It is not. It is just data about what our sensor is seeing. The histogram is just data, and it is useful. Use it. Do not be afraid of it.
Trigger
A newsletter I received today triggered this semi-rant. But looking back, I see it has been over 3 years since I wrote about histograms, so it is probably time to revisit the subject. This actually is a subject I feel some passion for and believe it needs to be better understood by photographers.
The newsletter author declared that our histograms lie. I realize that click-bait is commonly used to try to get people to read articles, but I still feel it is being somewhat underhanded. Now, in fairness, the newsletter author made some valid points – except for the part about histograms lying.
What is a histogram?
We see this graph of some data and maybe it does look complex and mysterious if you are not used to working with data and don’t know where the data comes from. Let’s get over that by understanding how simple but effective it is.
By convention we play like our cameras measure light in a range of 0 to 255. There are no units: 0 represents black and 255 is pure white. The convention came from the history of early digital cameras. It is obsolete today, but still used. That is a topic for another day.
So there are 256 possible values of brightness (0-255). If we go through and count the number of pixels of each value – the number of pixels in the image that have value 0, the number of pixels in the image that have value 1, etc. – and put them on a graph, we have a histogram.
Here is a simple example:
Again, black is on the left going to white on the right. Even without me showing the actual image, we can see that there is a “bump” of dark values on the left and a larger hill of bright values on the right. In between is a relatively low and even count.
What can we learn from this? It is a black & white image, because there is no separate data for red, green and blue. There is high contrast because of the hills at the dark and bright ends. It is bright but not overexposed. There are deep blacks, but not enough to have lost important information. So, even without seeing the image, we can tell a lot about it. Is the image exposed “correctly”? Ah, that is the question my rant is based on.
This is why histograms are useful. They are useful data about our image. It gives simple information to help us understand our exposure better.
Benefit
Today’s mirrorless cameras bring us the amazing benefit of real-time histograms. We can select to see the histogram live in our viewfinder or on the display on the back.
What is the benefit? We see an immediate graphical view of the exposure the camera is determining. In the example above, we can see that the light tones are very bright, but not overexposed.
I routinely use it to watch for “clipping” of brights or darks. If there is a large hump of data jammed up against the left or right edge, that is probably a problem. I will often choose to override the camera’s exposure determination to avoid these peaks.
Again using the example above and knowing that my camera was in aperture priority mode, we see that it chose 1/750 second as the shutter speed. That works OK in this case, but if I did not agree, I would have easily used the exposure compensation dial to adjust the exposure. I do this a lot.
So the histogram is a quick and easy to get a feeling for the “shape” of the exposure.
They don’t lie
Now coming to the basis of my rant: histograms do not lie (actually, they do; I will say how later and why it doesn’t matter).
The newsletter author gave the example of a picture of some fruit on a dark table with a black background. She said the histogram lied because the camera did not give the exposure she wanted. It tried to make the whole image evenly exposed.
No, the histogram is just a straightforward measurement of the data. If you take your temperature but don’t like the reading you get, it is silly to say the thermometer lied.
What the author was describing was that she wanted to expose to have the same look as the scene she saw. This was a case of disagreeing with the camera’s matrix metering calculation. It was doing it’s job of trying to capture all the data that was there and preventing blown out blacks. But she decided to use exposure compensation to force the camera to expose the scene the way she wanted.
The histogram did not lie. As a matter of fact, she relied on it to do her exposure compensation values. She used the histogram to determine how to override the camera exposure calculation.
Actually, I would have used the camera’s original exposure determination. I like to have all the data available to work with. This is called exposing to the right. Bringing the brightness down in post processing to the level she wanted is simple, non-destructive, and does not add noise. Capturing the compensated image the way she wanted irreversibly crunches the blacks.
They lie
I said they don’t lie, but they do a little. For speed and efficiency the histogram is derived from the jpg preview of the image. Same as the preview shown in the viewfinder or camera back. If you study jpg processing you will see that it alters and discards a lot of information to give a good perceptual result.
So the histogram is not actually looking directly at the literal RAW data from the sensor. But there is little observable discrepancy. On my camera, I find that it exaggerates the highlight values very slightly. Still, I typically back the exposure off to avoid highlight clipping, so it adds a little conservatism into the process.
Trust the data you see. It is good enough.
They’re not the photographer
The histogram gives you data. It does not determine exposure. People talk about “good” or “bad” histograms. This is a misunderstanding. There are no absolute good or bad ones. What counts is did you get the exposure you wanted.
There are valid artistic reasons for shooting what some people would consider bad histograms. If it is what the artist wants, it is correct.
Histograms give us a reading of the exposure. They do not determine what is right. It gives some insight on what the automatic exposure calculation in the camera is trying to do.
Use it
The histogram is a brilliantly simple and wonderfully useful tool. We are lucky to have real-time histograms available to us now. It is a game changer. But it is just data. Do not be afraid of it.
The histogram does not lie. But it does not automatically ensure that the exposure is exactly what you want. You have to sometimes take change and override the camera settings. When you do, the histogram is there showing you the result of your decisions.
It is not magical or mysterious. It is a great tool. Use it. A craftsman know how to use his tools.

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!”.

Craftsmanship
I have written a few times about how intent and expression are more important in a photograph than craftsmanship. I don’t want to leave the impression that craftsmanship is unimportant. It is critically important for a serious artist.
What is craft?
Craft is defined as skill at carrying out one’s work, or an activity involving skill in making things by hand. I believe an artist first has to be a craftsman. Proficient with his tools. Using our tools and equipment must be second nature.
Craftsmanship is usually a learned skill rather than an innate talent. Sure, some things are easier for some people than others, but it still has to be learned. Lots of investment of time and practice.
When we get skilled at the craft, the mechanics recedes into the background. It becomes a support and enabler for our artistic vision.
Perfection doesn’t make a picture
I have argued before that perfection of craft does not make a great image. The classic statement is Ansel Adam’s quote that “There’s nothing worse than a sharp picture of a fuzzy concept”.
It might be better to say craft alone does not make a great image. It is a table stake. You need it to get in the game. An excellently crafted image may not be great, but a poorly crafted image is very seldom great.
Craftsmanship is the base
Craftsmanship is a base we build our work on. But it is only a base, one of the legs of the stool. We also have to have vision and creativity and the drive to express them. I believe this expression cannot happen without solid craftsmanship.
I have said before that photography is one of the most technical of the arts. We are dependent on our equipment. Knowing how to use it correctly and effectively is absolutely critical to success.
We must study and practice and drill until it becomes second nature. Have you trained your hands to just “know” where the camera controls are? Can you use them in the dark? With gloves on? Can you quickly and almost instinctively determine the exposure solution that aligns with your intent for the image? Are composition and framing decisions happening rapidly in the background with little conscious thought?
When you’re out in the field working a scene you like, you don’t need to spend time juggling the technical tradeoffs in adjusting the camera. This distracts you from the artistic side. For instance, recognizing that this scene needs about f/8 to get the depth of focus you want and, since you are hand holding, at least 1/200th second shutter speed to insure a crisp image. Given that, are you willing to go to ISO 1600 to get these settings? These decisions should be almost instantaneous and subconscious.
This is not to say you are operating by habit or on automatic. Quite the opposite. It is a state of flow. You are channeling all the craft you know to focus on the moment at hand. It is exhilarating.
Photography is a craft
Photography is a craft. Most arts are, but it seems more obvious in photography. We cannot create without our tools. And we cannot create well unless we are proficient with our tools.
Let’s take a quick look at the chain of technologies required in photography.
On the capture side there is the camera, of course. They are not trivial anymore. The user manual for my Nikon Z7-II is 866 pages. That just describes all the settings available, not how to use them. Becoming skilled at using one of these is formidable. Luckily, most of us only use a subset of the capability.
And how much data do I need for what I am doing? Shooting full frame 40MPixels and above requires much more refined technique to achieve great results. Maybe what I’m doing today would be just fine with a 20MPixel APC camera. Do I have large and fast enough memory cards for my shoot? Enough batteries?
There are the lenses and filters to select. It takes training to understand the effects possible and how to select the right look for the situation. Should I use a zoom lens when I know it is theoretically possible get a little better sharpness with a prime lens?
Am I in the camp that says all images must be shot on a tripod? Or am I a hand-held guy? Or either, depending on the situation? Shooting hand held, do I know the techniques to get maximum sharpness? Or the techniques to shoot moving subjects?
What about capture file formats? White balance? Camera profile settings?
Processing
That’s just the capture of an image. If you shoot RAW images, which I hope you do, the images are useless until they have been processed intensely.
First, they have to be transferred to your computer. Do you have enough storage? My main image storage is currently using over 7 Terabytes. Then there’s multiple backup of that.
If you are processing high resolution files you will need significant computing power. Lots of memory and graphic processing power. And a great, color calibrated monitor. Hopefully of 5K or more. That power is required to be able to process images fluidly without having to wait for the machine to catch up. Waiting really breaks your concentration.
And of course, you use a color balanced process. Your camera and monitor are calibrated and you are using a wide color gamut system like ProPhoto RGB. A wide gamut allows lots of freedom in editing.
All that processing takes a lot of time. So when you go out and shoot 1000 images, don’t forget that they have to be processed, and culled and keyworded and filed.. For me, processing an image takes anywhere from 1 minute to 8 hours.
Output
How you process an image depends on what you are using it for. Getting something ready to post on social media probably just requires some color and tone correction and maybe cropping. Preparing an image for a print could take a long time.
Let me take the path of going to a print, since that is my preferred utilization.
A print is a physical object that is perceived different from an image on a screen. The viewing time of a print is usually much longer than an image on screen. As such, it generally needs to be processed to a higher standard. Very careful spotting – removing sensor dust spots – is critical. Spending time removing or mitigating distracting elements is usually important.
Many of the remaining decisions center on the characteristics of the final output. What size will the print be? What paper will be used. All papers have different properties and strengths and weaknesses. The paper can make the print look very different. Is it matte or glossy? Coated or uncoated? Heavy or thin? What color is it – papers aren’t necessarily white.
To get an estimate of the final result requires turning on proofing during the editing. The computer attempts to simulate the final printed result. Of course, to do that, you need accurate profiles for the paper and printer combination. But that is just an approximation. It may need more than one attempt. And what about out of gamut colors on your print? Handling those can be tricky and exasperating.
Build on it
That is a lot! And this is just talking about still photography. Photographers have to be expert at most of what I described. That is some of the craft involved. All of this craft has to be used intelligently in the process of making a great image. It’s why I say that photography is one of the most technical and craft-based arts.
But as much as we sometimes like to burrow into the fun details, the craft is a base. Build your base solid. But on top of the base, we need to build our artistic sensibility, our vision. We have to establish our style.
Craft means knowing how to use your tools to achieve the results you want. Maybe that is an ultra crisp, tack sharp image. Maybe it is a flowing abstract with no sharp pixels. Yours might run to dark and moody and underexposed. Somebody else might be bright and high key. Those are your choices. Whatever your vision leads you to do, it is your craft that allows you to achieve it.
