This little exercise offered a surprising number of opportunities. Wide angle shots, low angle shots, panned shots, landscape, macro, still life, action shots, portraits, etc.
Also, kids are, hands down, THE most interesting human subjects I could ask for. They're candid, hyperactive, unafraid to show emotions, and they don't give a damn if a camera is pointed in their direction. I would have loved to stick around the playground a bit more, but the adults might mistake me for a kidnapper, pedophile, or something. It would be nice if grownups could just let go of their worries more often.
