I recently bought an 35mm from a pawn shop. I didn't buy it for the camera but more for the lens. Anyway, when the guy rang me up he remembered that the camera came with a case. Once I got home I found there were 7 rolls of used, but undeveloped film in the case. Curiosity got the best of me and I took them to Wal-Mart and had them processed and the pictures put on a CD. They turned out to be just normal pictures from some guys road trip. Nothing professional at all about them. I went back to the pawn shop and they located the guy who sold them the camera and I got his pictures back to him. So here's my question. If there had been some type of obviously professional pictures, but for simplicity's sake, no people or human models, could I legally sell them? I know usually the photographer owns the copyright to the images when he presses the shutter release, but since he sold the negatives, and I bought them, would I now own the copyright, and therefore be able to do whatever I wanted with them? I would probably do the same thing I did in this case, but I'm just curious. Thanks.
