This is purely my personal opinion and philosophy so please take it as nothing more than that. While these fancy scripted signatures look attractive and "professional", they never resemble the real handwriting of the photographer. I am the first to admit that my own cursive handwriting is not very attractive, but I would never purchase one of these fancy logos with cursive or scripted name. Anyone who ultimately sees my handwriting on a contract will know it isn't my handwriting on the logo. If you have beautiful handwriting, use it. If not, practice until you get something you are happy with and can reproduce. Take a picture of your own handwritten signature and turn that into a logo.
Again, this is my own personal opinion and philosophy.
