Photography Logos

How does a photography name work?
I only do photography as a hobby and I would like to copyright my work with some kind of logo. Would I have to use my name? Or if I choose a name like, Whatever Photography, does that have to be copyrighted or something? Or should I just use my name?
My name is Kalene. It's not very professional sounding.
But if you could help me, it would be appreciated.
by putting your name on a photo it is not copyrighting it you are watermarking it a photo is copyrighted the moment you take it and it doesnt matter what you put on it just as long as the watermark leads back to you
