Hi! Recently I have been contacted by someone who is interested in printing one of my pictures. I just put my pictures online and I had no thinking even about someone doing that! So my question is... what do I do? Do I provide the full res pic, so he can download and print it? for free? do I add my signature somewhere so if he hangs it, everyone seeing it, knows I took it? Do I need to sell? (this feels silly, because it is the first pic ever...) What would you do? Thanks!
