One must submit photographs to more than ‘judge’.
I had submitted some photographs to a stock photo site, BS, and most of them were rejected. What I called ‘depth of field’ they kept calling blurry, or grainy, even though the subject was crystal clear and sharp.. Every rejection I got from BS, I could feel myself slouch more and more, thinking that maybe the pictures well and truly sucked.
Then a week later, I get several emails from FT stock photo sales, and all of them are accepted, and commented on by the staff as exemplary work. I started sitting up a bit straighter, and feeling a bit more secure in my ability to take decent photographs.
And I have sold three of my photographs at FT. So, I guess I am doing something right.
