Hi,

I've been using my flashes for a while, but today was the first time I shot something moving fast (a girl dancing). Some of the pictures seem soft because of motion blur, in particular the hands that move fast, although I always thought that the flashes were fast enough to prevent this!

Basic setup was rather simple, two Elinchrom D-Lite 4 it with umbrellas, the 5D2 in full manual with 1/100 exposure time which guarantees to not miss the flash but is fast enough to give me a black picture from only the not very bright overhead lighting.

Are the flashes not as fast as I expected, or is it that the two of them don't fire exactly at the same time (triggered wirelessly with an Elinchrom SkyPort Eco trigger), or is there anything else I might be doing wrong?

Thanks, Colin
