This type of discussion always piques my interest. Previously we were
discussing fill flash and some ideas (misconceptions really) I had were
cleared up. So now we are working on flash sync and I have some more
ideas : ' ).
1. My OM 1n and 2s have curtain speeds of ~1/90 sec. If you have a
flash source that has a duration of (1/90 + Shutter speed + a fudge
factor), the exposure would depend on the uniformity of the light
output during that time. True or False
2. Is it possible to "String" a small number of flashes together with
a delay circuit between each to approximate the situation in item 1? I
have two A11's, they are fairly cheap and small, but it wouldn't be
pretty.
3. Earlier in this thread someone mentioned "modeling lights" as a
solution. Does anyone know how long it takes a 12v Halogen Flood light
to come on to full power? Is it possible to use these as a flash bulb
using the "FP" setting then turn them off automatically to conserve the
batteries. I am thinking of the type of lights I have on my bike and
with reasonably small batteries they last for an hour or two. Maybe
using smaller batteries and a "Flash" circuit the lights could yield
acceptable results. Filters may / will be needed to balance the color.
4. Basically same as above but using Camcorder Auxiliary lights.
5. Back up lights from my SUV ( getting this thread back to the
obligatory SUV content)
Thanks for the education,
