So last night I shot a music recital. It was about 20 kids/adults varying in ages from 4 to 40 playing piano, drums, and guitar. I decided I wanted to try and remote trigger a camera from the catwalk above the stage. So, I took my ebay triggers, and my remote and frankensteined a way to fire my 20D everytime I clicked the shutter on my 10D. worked wonderful, but I'm not sure how many keepers I got. I haven't had a chance to look at them yet.
