I had taken a photo at an event I attended. The magazines photog did not get the photo. The event's hired photog didn't get the photo, but I did. The magazine and I had an agreement on payment, which is ridiculously and embarrassingly low. The photo is at the top of the article and literally takes up 1/3 of the page, and across the fold. Magazine has NOT fulfilled their side of the agreement. There won't be any doubt who took the photo, I was at least given credit. magazine is on the street now, and my agreement was a one year subscription. How long should I give them, and what should my next action be.
