Thanks for sharing the picture set. Looks like the weather was nice and everyone had a great time.
Could you share what camera/lens combo you used? The pictures were all very natural looking.
Saturday's weather was a bit questionable (hence only a few pictures), but Sunday was beautiful.
I'm using a Canon EOS 40D with a 100mm f/2 telephoto lens (given the crop factor on the 40D, it's an effective 160mm lens, I believe). I love getting environmental portraits of kite fliers, especially when I can catch them unaware of the camera. The longer telephoto means that I can stand well back and still get the shot.
