Style isn't subject... so saying that "I don't shoot buildings, I'm a portrait photographer" doesn't make much sense. Look at the Simon Sez challenges where several people enter images of a similar thing, yet they all reflect the eye and mind of the photographer. Someone once looked at the stuff in my 2d portfolio and said that they were all the same, and I thought, "huh?!?" Subjects ranged from harlequins to cats to pegasi to spaceships... and materials went from colored pencils to ink to watercolor to scratchboard... sigh. Some things such as composition and line quality are going to be constants, though. Whether I'm photographing a tree, drawing a tree, or plopping a tree into Poser space, there is a certain way that I'm going to frame it, and that way will be identifiable whether I think about it or not. I try not to think about it. Then it becomes artificial. BTW, your contest idea sounds neat. :) Carolly
