I've got 2 AB800s with 36"octaboxes and some umbrellas, a 580ex and a couple of pocket wizards. I've found that shooting people i'm short one light or at least a trigger for the 580ex. I can usually get by, but an additional trigger or light would be great.
I rushed in strobes to shoot cars, but forgot that i needed a portable power source. Which i still haven't gotten. Anyhow, here are a few of my indoor people shots....
One light on the background with a 20degree spot, one octabox just in front of the camera bout 4' higher than the camera. Should have used the 580 to bounce off of the ceiling for a little more light. Or just turned up the front light.
Octabox about 3 feet in front of her face and a 20 degree spot on her back.
Same lighting set up as above, just moved camear position.
Don't remember the set up for this one but i think both lights are on her, prolly octobox to the rigth and spot on her hair.
Octabox front left, spot on the background
