I like to pretend that I don't get posed shots of kids, but sometimes even if all you're doing is taking pictures of a kid being a kid, he'll end up in kinda a posed position.
I found this gem in one of my untitled albums in my aperture library (yes, I need to work on organizing). Not only is it a great looking, posed portrait, but I think it totally still looks like Rowan! My portfolio needs more than great pictures of Rowan, so as soon as swim season is over, I will be working on booking some portrait sessions.
