I have been taking pictures at a Horse track for the last couple of year to build up part of my portfolio. I have never sold any of them but have submitted them for editorial purposes. I had someone recently contact me inquiring about purchasing a print for their home. I have read the Law in Plain English for Photogs but I am still a bit unclear as to whether I would need a release from the Owner of the horse and the excercise rider since this isn't commercial I wanted to find out if anyone had any experience with selling prints like this. I see the same types of images of races both horse and Car/Nascar and Indy races and I know a few of the photogs and know they don't have releases but yet they still sell. Is it illegal without a release if it isn't going to be used for commercial reasons in any way?
Thanks
