It occurred to me that our neighborhood school yard has a little plastic house built into the Kindergarten playground equipment, complete with windows, so I took the kids out to see what we could do. I also took my SB-600 flash unit, with the goal of trying to create decent lighting despite the harsh mid-day sun.
I set the tripod low, to be on a level with the play area equipment, attached my 14-24mm at f/8, and then walked around with the flash and the camera remote, keeping the camera more or less in one place but experimenting with the light position. Meanwhile, the kids came up with every which way they could be in, or spilling out of, the window. We had a great deal of fun as the kids were eager to try all sorts of things.
In the end, the sun backlit the kids, while the flash provided nice fill in most cases. As for what to submit to the weekly assignment, I am leaning toward one of the ones where Megan is upside down.
