by Gavin Seim: We all see differently and that’s good. We should never stop working to improve. One might even contend that you can never really “master” photography. But perhaps you can get pretty close, if you really nail down these and perhaps a few other essentials, taking control of the way you plan and capture images.

 

1 – Your Tools – A camera does not a photographer make and neither does fancy software. But don’t underestimate how important the tools are. Some sluff off knowing their gear, settings, apertures, shutter speeds, lights, software another tech stuff. That’s usually a fatal mistake. Don’t fall into the crowd that says “I’m an artist, so I just don’t get into that technical stuff.” Photography, like most arts, is both art and a science. And if you don’t master both, you’ll never be a master of the art.

2 – Storytelling – A great image has to have a subject and a story that can reach out and grab people. Uninteresting subject matter, too much clutter, messy composition, bad details, distracting lighting, the list goes on. Fail at any of these and you’ll never be great at photography. It’s hard to nail all these elements down with anything but years and years of practice and experience. But then, no one said this was easy. Until you can start clearing out distractions and really convey feeling. You’re just making snapshots. Those are fine, but remember. Everyone else it making them too.

3 – Tone Control – This may be the biggest of all. And yet it’s finer points are the most ignored. It’s the one most will never truly master. Everything needs to lead to the subject. And mastering tone gives you that power. Tone control is about seeing light in your head, understating how to manipulate it, and understanding how to control tones to make your subject and your story, sing like the sound of music. Even most professionals have not nailed down tone control, but until you do, you’ll never be fully able to control your light or the impact of your photographs.

If you’ve mastered all these things, then you should be writing this instead of me, because I’m still working on them. But working I am and getting closer each day. Just remember that a camera is no more an artistic tool than a typewriter. It’s knowing how to tell a story with light, tone and line that matters. Like nearly all arts, there’s an aspect of science and an aspect of art you must master. Otherwise you’re just another person with a tub of paint or a ream of paper. For more

So lets get to work. Science + Knowledge + Vision = Art

River Forks, Snoqualmie National Forest, Summer 2011. Non released example image, 8 minute exposure at ISO 100.

This is for you photographers. It’s an 8 minute exposure I did just after sunset on the river. I processed it with the Velvius preset from Power Workflow3. It’s not a stunning image and that’s not why I posted it. I felt it was a good image to use to talk a bit about pixel science.

To me, what merits discussion is the noise. I’ve done images much longer than 8 minutes. The longer the exposure, the more potential for noise to be generated as the sensor heats up. But, as myself and some others have found, the warmer the environment, the worse it seems to get. It was probably in the low 70’s here in the mountains, and the warmer temperature seemed to make a great deal of difference compared to images I’ve done in cooler environments.

Look at the image and the crop section I posted below. The noise produces a banding-like effect on the frame that really reduces quality. The large color artifacts are easy enough to fix, but there’s an almost patterned, under-the-surface noise that really is a challenge. And this was with in camera long exposure reduction turned ON.

I talked about this type of noise in depth in the making of 140 Minutes of Night ( 2+ hour long exposure) and looked at techniques to deal with it, but it’s not easy to correct. When you get into bad heat noise, the plethora of noise plugins and tools we have won’t just take it away. Well, they will, but only at the cost of losing a lot of detail everywhere else. And that’s just not acceptable.
