Single SB-800 from the left as key light, zommed at max, and with Lumiquest Snoot. I've drag shutter for decrease ambient light and increase contrast.
This time ive used bare flash without any light modifiers. Bare flash is good when you shooting single person portarit because hard shadows did not make ugly pattern on other person. And bare flash is powerful enough for shooting even at sunny-16. So - think of the bare flashes ;)
Triggered with Wireless remote SU-800.
