Strobist info: 3 flashes, all set to roughly equal power and adjusted by eye. A Canon 580EXII, gelled red, on camera right behind the model level with her hips, goboed to prevent lens flare. A Sigma 530 DG Super, gelled blue, on a light stand, with a snoot pointing at the model's back. A Yongnuo YN460, gelled green, set similarly to the red flash (but to camera left). I think for the blue/green filters I used layers of CTB/CTG filters, whereas the red is an effects filter.
