A while ago I had one of two images refused because they were two shots of the same subject with just small change in the angle of the shot. I was dissappointed, even angry! Those two images had been accepted everywhere else... how could that be!
Now, a short time after this, I have a level two image and I just hope it keeps selling. It has to be the fastest level two I´ve ever got (out of the very few I have - I´m still just a newbie to stock photography). So if the other image had been accepted... I wouldn´t have it. Simple as that.
Now I´m glad the second image was refused. I guess we have to trust the editors´ judgement. They are most of the time right (like 99% of the times).
