I'm new to this forum and looking forward to joining in. I've been contacted by a wildlife artist who has asked what I'd charge for my photos to use as references for his paintings. He's interested in one particular image at this time. He'd like to use it as a reference for a painting that he will submit to a postage stamp contest...something he does regularly. Any ideas on what I should charge him for this usage? BTW, I happen to know a lot of artists and this question has come up before. In this case they were asking for permission to use my photograph as a reference for paintings that they would put up for sale. Also, I read on this site about PLUS being used to generate a license agreement. I couldn't really find an appropriate category for this type of usage. "Personal usage" was as close as I could come. Any suggestions would be very much appreciated.
