Until the painter actually starts, you know, painting. The original claim was that selection is the basis for photography. ("Well, duh", I tell myself before pressing "Post Reply", "very deep, Leo.") I didn't think the replies were very responsive. I could have cut and pasted them into a discussion about cave wall painting. You don't have to believe me when I say selection is the basis for photography. You can just observe yourself in the act instead. Have a nice sit to think about what you want to say. Channel your delicate artistic tempers. Do the vision thing. Now look through the viewfinder. Chimp. Reposition yourself. Twist a dial. Change the lens. Satisfied? Press the shutter. What happened? Did you synthesize something on a blank sensor? No, you selected something and pressed the shutter (because if you don't press the shutter, then you're just looking.) Let's take a look. The good news is it's unmistakably a photograph, just as I suspected. The bad news is, it's no good :-( Ah, well, nevertheless. Fact is you'll take thousands of bad photos for every good one. The world is an uncooperative place, you want to select for this but it gives you that. I dunno, maybe learn to exploit what's there, or take up painting and synthesize what isn't.
