Hi Kennedy,
I don't know how it is related to flash photograph. Except for Super FP
flash, OM4/Ti is lock at 1/60s with T-series flashes attached. Flash
will emitte only when the shutter is fully open, nothing in between, not
during shutter curtain is travelling. My last mail was talking about the
blending of shutter curtain and flim not the blending of day light and
flash light.
