| p.1 #8 · Bare bulb for wedding receptions? |
The main problem with going bare-bulb at a reception is the relative intensity of the light very close to the strobe -- if you're shooting toward a bare-bulb strobe, whatever is right beneath it (and if the ceiling is low enough, the ceiling right above it) could be heavily over-exposed compared to the subject.
The reflector allows you to feather and flag some of that light off of the subjects nearest the light: if you aim the light up at, say, 45 degrees, the bottom part of the reflector flags the bulb for the subjects immediately below the light, and the upper part of the reflector bounces some fraction of the light down toward subjects starting, say, 5 or 8 feet away. The ceiling may be blown out, but, hopefully, the part of the ceiling that would be blown out will be closer to you and therefore less often in the frame.
