i'm doing some editing on a project. I have a wide exterior of a woman entering a JC Penny where the store sign is prominent. Will I have copyright problems using this? If i want to get this on PBS, will there be a problem where it looks like I'm trying to advertise the store? I didnt and the store didn't pay me (heck, they only gave me oral permission to shoot inside if I only shot my subject and nothing else) but i could see how it might look otherwise. I really want to use this establishing shot, but I dont know if I'll have a problem. Thoughts?
