We went with the white background so that we could capture every piece of our messed up do's. I made chris brush out the mohawk glue that keeps his hair prickly sharp even after a night of sleep. And a few sleepy eyed shots later we got it.
We were using the 50mm 1.8 so Chris had to back up to get all of the madness on my head. The white background had a single light on it so that it would be the starkest white possible.
