Have I got a deal just for you!
I wanted to try out that Hill / Greenberg look in a self portrait. I used 5 flashes (the 6th didn't fire).
I put lots of baby oil on my face and hair to get more reflectivity. eww.
SB-25 and SB-600 through white umbrellas on each side of a cheapo light socket strobe in a silver umbrella.
Cheapo light socket strobe for hairlight and 2 Vivitar 285s behind and to the side aimed at my neck. (the right side was firing, but out of sync or something).
