Light Neck Guitar Hero
My favorite from the shoot. The grid snooted flash provided a great light pattern in the background. After a few shots, I realized it worked really well with the neck of the guitar and added some natural emphasis and didn't require me to do any post-processing.
You can also view it on black.
Strobist info: Canon 580ex into shoot-through umbrella cam left and a Canon 430ex with a grid snoot shooting into the background. Triggered by PWs.
