UPDATED WITH ANOTHER SWING AT DESIGNS BELOW ...
I'm tweaking my logo, and have sort of narrowed it down to this type of thing.
I like the first one best: it can be reproduced in B&W or any color I could possibly want. I think it makes more of a simple, graphic statement.
The second one adds another color, but it also can be easily converted to B&W.
The third isn't my favorite, but my wife thinks the logo should say "Photography" because she thinks it sounds more sophisticated. But I use "photo" with my Web address because my name was long enough already.
Thoughts? If you say, "I hate all of them," be prepared to share with the class a suitable alternative. Thanks for looking!
