Roger,
I'm honored by the reply, but, in addition to the photographic effects, I'm going for the authentic effect of actually using bulbs around people in 40s clothing listening to Big Bands. It just doesn't seem right to use something as modern as electronic flash. But I will keep that in mind when all I want is the effect of the big reflector. If I use the rear shutter, what shutter speeds would work with a bulb (press 5, 25 or maybe a 22 if I feel like scaring the heck out of people)? I don't really have any FP bulbs.
