If you look at enough of my work you'll see I'm a sucker for compositions like this one, with strong yet simple geometric shapes, bold contrasts, and dynamic tension with an element of mystery. But then what would you expect from someone who has worked as a graphic designer, technical writer and instructional designer? I know the world is chaotic and often absurd but I still like putting a neat frame around it. So sue me.
You can tell a lot about a person simply by observing the choices they make in food, friends, clothing, music, cameras... the list could go on indefinitely. A few caveats apply, of course: You can't tell everything there is to know about someone based on any one choice. It's also important to remember that traits are relative, not absolute. Just because someone is more conservative than you doesn't mean they are a Conservative and you are a Liberal, it only means you are at different points of a continuum. With these qualifiers in mind, however, if you look at a series of related choices you'll soon have a pretty good idea of what sort of person is making them.
When it comes to photographic choices, someone who prefers to shoot with a large-format view camera is a very different person than someone who uses a 35mm rangefinder or even a full-frame DSLR. They are likely to shoot different subjects. Even when the subject is the same their working methods will be quite different--and therefore the results.
If your camera forces you to work slowly and methodically and to limit your exposures because of the cost and bulk of the media, you're going to put a lot more thought into each photograph before you release the shutter. In contrast, if your camera allows you to work quickly and at no incremental cost for each exposure, it can be easy to fall into the habit of clicking first and thinking later.
This is not to imply that digital photographers are lazy or that owning a digital camera leads to sloppy technique. If that's what I was trying to say I'd just come out and say it. What I am saying is that when the cost of shooting is so low you can choose to shoot a lot more, when you shoot more there's more evidence of what choices you tend to make and it's therefore easier to determine your strengths and weaknesses as a photographer. (Yes, I know, I could have put all that into the first paragraph, but I like to take my time.)
Now here's the good part: If others can gain insights into who you are and what you're about by looking at a collection of your photographs, so can you. Are you the sort of person who likes to play it safe or are you constantly pushing the envelope? Do you keep making the same mistakes, and if so, why? What impressions do people express when they look at your work? Are they the impressions you were expecting? Are they seeing something you don't, or not seeing something you thought was obvious? These are questions worth asking because it's otherwise hard to expect others to see something in your work that you can't see yourself.
