I found a Shutter Speed homework assignment on a tutorial i'm looking at, and I took the kids to the park and did some long exposure pics of them holding glowsticks and I loved the results. I know there's room for improvement and i need more technical work on it (this was the first attempt, after all), and I'm sure i can choreograph some better shots, but even after one practice shoot I can just see how much potential there is in something like this.
I personally love the swings picture because it communicates the personalities of all three of my kids without actually seeing them.
