I thought I'd try my hand at doing some stock photography. After all, I spent a lot of money on this equipment and it'd be nice if I could pull some revenue back. Pick a nice easy subject -- street signs in my case -- and upload some gorgeous shots. Take some care and should be an easy self-fueling hobby, right? Holy god. I found a moderately sized site with a low minimum payout and very fast turn-around on image review. 21 submitted, one accepted. Auuugh! Complaints about noise and CA that I can barely make out. Exposure complaints nearly across the board, either because the sky's blown out or because the sign's too damn dark. Some complaints that sharpness isn't quiiite perfect at 100% on a 12 MP image. (I assume. They always give vague reasons.) I figured there would be a learning curve, but these people are extremely unforgiving. Submitting an acceptable 100% (non-resized) image seems near impossible, with sharpness and CA constraints that simply exceed what the lenses are capable of. I'm going to try re-submissions with resizing waaay down, and I'm clearly going to have to spend a lot more time with histograms. The need for technical perfection here could get exhausting really, really fast...starting to wonder if maybe I'm out of my league.
