One of my friends is really good at photography. I mean really. So I was trying to find a place where she could sell some of her pics and I came across these 2 places. One is a company called Alamy. You can submit photos here. They check for quality and if your pictures past the test, then you are in.
Fellow blogger Carbon monoxide suggested the other. It's called Deviant Art. You can register and become a deviant. Yes... that's what yr called after you join. It's like a community where people can comment on other people's art, you can put your work up for sale or just browse through the pics posted. This is more related to art in general rather than photography alone. They have a chat and a forum. Some of it is really good. Click here to become a deviant
