Up to No Good
I wanted to emulate my previous shot's setup outdoors; so that's just what I did. The only difference in this shot's setup and the indoor portrait is the addition of a reflector that served two purposes:
1) It blocked the sun from hitting my face.
2) It provided a little bit a fill light.
strobist: 1 White Lightning x1600, above camera, diffused by a 22" PCB HOBD with diffusion cover in place. 2 White Lightning Ultrazap 1600s, camera left and right, behind subject, diffused by stripboxes. Strobes triggered via Cybersyncs and Cyber Commander; powered via Vagabond IIs. Setup shot here.
