I really like the overall concept. I would like the 'flash' dropped and maybe a camera with a little more whimsy to it. Little more artistic and quirky. I like the rectangle on entry #23. The font is spot on!
your font and spacing on #40 is perfect! I like the rectangle box around the entire logo as well. the camera still isn't totally what I would like to see. A hand sketched camera or even a more modern/blocky camera may be a little more our direction.
