Hey i was wondering. I took a few pictures yesterday (political stuff of a company) and i offer to gave them the pictures on cd, no prints. But since this is my first time doing this i don't know if i should ad some signature or watermark to the pictures? like my name or company name on the pictures, really small but there...? if that's the case, should i do that with every picture on the editing software? 1 by 1?
