Here are two sites that you can submit photos for publication. I heard about Shots Magazine, an “independent, edgy and fascinating publication” from Akos Szilvasi, a great portrait photographer who is leading a portrait photography discussion group I hope to get a chance to attend.
Ed Friedman introduced the group to Onexposure. As he write, “One submits photos and is either accepted for publication on the site or not. The screening is process interesting. There is a panel of screeners who look at all submissions. They can accept or reject a photo. If they are on the fence, they throw it out to their members to vote for or against publication. If you get rejected (as I mostly do!)you do get some feedback as to why. If you disagree with a decision of the screeners you can appeal. Also, if rejected one can post the image to a forum to see what other viewers think of the image. I have done that several times and gotten good feedback from other members. It is free to join.” Ed also has a great photo site himself.
