Me. DH cannot take pictures although he's doing better with his digital (because he knows he's screwed it up immediately!) but he also never prints them.
EVERY picture he took on our last WDW trip of DD and I has the camera strap across the middle of the picture. I put 'em all in the scrapbook anyway with little notes at the bottom "Look...here's the camera strap at the CoP!"
I take the most but my dd6 and dd4 take lots of pics too. Both dd's have good digital cameras and its fun to see the world from their perspective sometimes.
My dad definitely takes most of the pictures, he's obsessed with his digital camera. My mom and my sister don't really know how to use the camera that well, so I'm probably the one that takes the most pictures after my dad.
I take my own pics. My mom used to take pics but my stepdad is possessive and has taken over the camera. So our last decent pics are from about 4 years ago-before he moved in.
