I am a sports photographer, and I go to a lot of AAA games since a stadium is close to my house. I take my gear and shoot, only for me, but also to build a portfolio. Even though I see a lot of people with DSLR's, I still asked for permission to shoot, which I was granted, and I signed nothing or agreed to anything from the person that said I could shoot.
So, the question is: can I sell any of the pictures that I take? I was told by another sports shooter that frequents the games that I COULD NOT sell my pictures, and that I should remove the "Buy" button from my SmugMug galleries.
I am in no way doing this for money, only for my enjoyment, and my portfolio, which doesn't hurt. And I doubt I'd ever sell any of my pics anyway, but wanted to be clear on this.
Any thoughts?
