Photographs are like any other object - they can be used as art, as a form of comunication, as a way of record an event or a memory, or any one of a million other purposes. And the fun part is that a photo if often used for many different purposes all at once - sometimes even by the same person!
My photos are primarily a tool for recording my memories of a particular place or time or event. Looking at a still image often brings back the memories with a clarity and sharpness I can't accomplish on my own, even years after the fact.
My photos often work as a form of communication. When I'm in a beautiful place, I like to try to capture a little of that beauty in a photo. I don't try to make the photo beautiful; I just try use the photo to open a window on the beauty of the original subject. The photo is the road, not the destination.
Lately I have been trying to develop a new skill - to create photos that are, themselves, objects of beauty. I seldom try to say anything with these photos, I simply want to create something that is intrinsically beautiful, at least to me.
So far, I have never been the type to take a photo in order to send a message. But perhaps one day I will be able to use my photos to say something, whether it's something important to me, or something important to others. That's a very difficult skill, but maybe I'll get lucky one day.
In the meantime, I'll just continue to point my camera at stuff I think is pretty, and push the button.
