I rarely shoot indoor portraits, but it can be a lot of fun. This photo session of our friends' boy was shot in my living room. I used two off-camera speedlights, a reflector, and a white background. The first speedlight is positioned camera-left with a shoot-through umbrella. The umbrella is very close to our subject so the light is very soft. The large white reflector to his left helps fill in the shadows. A second speedlight, up high behind the boy, is used to light the white background. (if the white background were not lit, it would appear gray) It's a simple, inexpensive setup. And it's lots of fun.
Hope you like,
