I find watermarks, signatures and logos to be super annoying. I figure, if someone wants to use my photo for something and not pay me for it then so be it. It is not like you are going to be able to print my photos off of my website and get a resolution that makes for framing. I can’t stand it when photographers mark their product but this also goes for clothing I wear as well. If it has a logo, then it most likely will never make it on to my body. Pros: Yeah we all know your name now! Awesome, high five! Cons: Looks unnatural, stupid, annoying and elementary. I find that you build your brand by having your own style. I can look at some photographers I admire and I do not even need to know who shot it, I can just tell.
