I love #17 with the tripod incorporated! Maybe with blue and the word photography a litter larger. and I love the simple font, but maybe adding colors will pop it out? Awesome!
Can't figure out what to do to make it work - I want to go with deep to med blues with black and/or white highlights - and want something to indicate a glass reflection.. Maybe a zoom lens on the camera with lens flares?
I like the lens center - maybe put the camera back on very to with some flares around it - cross the other A's in Barbara and make the B & W black to match photography.
