This is one of my first attempts at multi-flash hummingbird photography, done in Costa Rica a couple of weeks ago. Comments and critiques would be most appreciated. I'm also interested in purchasing my own multi-flash setup, but am not sure about which flashes to purchase (I already own a Canon 580EX II). Also what's the best way to trigger all of the flashes at once? Many thanks!
Canon 40D, 210mm, f/16, 1/200, ISO 320, multi-flash (5), manual exposure
