    Hi all,

    i was under the impression 2nd curtain sync flashed at the end of the exposure. i was trying some long exposures the weekend, with the plan to put people in the shot at the last second. The flash always flashed at the start and at the ens. Is this correct? Am I mis-informed? Thanks

    In 2nd curtain, the first flash is a pre-flash which measures exposure. The shutter only opens after the pre-flash - so it shouldn't affect the actual exposure.

    It goes: Pre-flash -> Open Shutter (Exposure) -----------> Flash -> Close shutter.
