My question goes like this, at my beginner level, is it worth or important to show ownership of my photo's with a signature or watermark? :scratch: I've noticed a lot of you more experienced folks have your photos marked with at least a signature. I know a lot about criminal law, but very little about civil or copyright law. Even though I don't have many photos worth anything right now, that doesn't mean at some point one of them I've already taken or will take may have value. Plus, with the digital age, it's easy to alter photos to make them your own and once they're out on the internet, they will always be out there. I've always thought posting on the internet is like putting a drop of food coloring in a lake, then trying to suck it all back out...ain't gonna happen... Also, would I need to be incorporated or have the signature copyrighted in order to take any action against someone using it? What rights do signatures or watermarks even actually give me? Would I then have the ability to tell someone they cannot reproduce, sell, alter ect my photo? Anyway, sorry for the multi part question. I searched the forum and didn't find any applicable threads, but if someone can link me to one, or another online resource, link away. Thanks in advance.
