What's the copyright status of a photograph taken by someone else using my camera?
Example A:
I gave the camera to
Example B:
I am out with friends. I gave the camera to
Example C:
I am out with friends. I gave the camera to a waitperson to take a picture of the group of us on my behalf. I never get the photographer's name or contact info. Do I have any right to reproduce that photo under copyright law? It can't be work for hire, because I didn't pay them for the photo. The implicit ownership of the photo is clear: it's my equipment and the photo was taken at my request. But the copyright status is unclear to me.
