No fill flash was used, since I had no of camera lighting. These were just taken with a 11am sun on the subjects backs, and an opaque plastic painters sheet behind them so the sun was coming through it. The were definitely cropped tight because that's as big as the sheet was, but I thought it was a cool way to get fun pictures in harsh sunlight. I like the backlighting, but definitely agree that some fill would have been nice from one side of the other. But straight on would have just flattened it more, right? Thanks for the comments.
