Strobist info: Sunpack 411s to the left and right, a little above the centerline of the picture. Left one in a homemade softbox, right one bouncing off of an umbrella. Wanted to do shootthrough, but I was getting too much lens flare. Equal settings @ 1/8, iso200 and f6.3 or so. The left is a little hotter since it's closer and none of the light spilled into the rest of the room, like the umbrella does.
Black background, black long sleeve shirt on the mom holding the baby.
Conversion in Lightroom, a little bit of playing with the black levels but otherwise a pretty straight forward conversion.
