Patricia requested info on this shot, so here it is
I took this with my 50mm lens ISO 100, SS 1/250, f/5.6. I wanted to get most of him in focus and stop the motion. I was laying on the ground just far enough in front of him that he wouldn't jump on my head and so I could focus on him. I also was angled so that the sun was to my left so I didn't have to deal with backlighting. (I tried the flair thing at another angle, but still haven't mastered that)
And Sarah asked about this photo, specifically the photo in the bottom right corner
I also took this photo with my 50 mm lens. ISO 800, SS 1/50, f/1.4. My living room has light from an east facing window that was at his back. I bumped up my ISO since there wasn't a lot of light coming in. I followed the rule of never having my SS less than the reciprocal length of my lens. I think I got a fairly steady shot because I was seated beside him on the sofa with a fairly steady hand. In a larger photo you can see that the focus was on the crook of his arm, but in the small photo you lose that technical oops!
I get my best photos of Ian when he is doing his thing and oblivious to me!
Hope this helps ladies
