I shot a whole heap of photos while he was playing, as I wanted to try and capture him while he was engrossed with what he was doing. That meant of course that he didn't stay very still! Combine that with trying to manually focus on his eyes as he moved around, and trying to stop my german shepherd thinking it was play time with me (seeing that I was on the floor) proved to be challenging :-) But I managed to get a few in focus.
This one was probably the best 'from the side' shot.
I've used a Lightroom preset on both of these by onOne called Grandmother's Lemonade with vignetting.
