For my first image post here at APUG I'll go with a self-portrait I shot when some new tools arrived from my dear friend the UPS man.
Mamiya C3, 80/2.8 (chrome), Delta 100 in DD-X. Lit by an Einstein 640 shot through a diffused 28" beauty dish about a foot and some change from my head. Scanned on a Canoscan 8800F. When I finish my darkroom this week I intend to see how this enlarges.
I shot this as part of a series to illustrate to a friend how to achieve "dramatic" light falloff. I got into inverse square law talk, and math, and she short-circuited. A picture is worth a thousand words.
