Ive been watching reporters photograhing celebrities and often see them taking multiple shots along with mulitple flash. When I try this I have to wait for my 380EX to recharge after a single shot. They dont appear to have a battery pack so how do they do it? Alan
Maybe their flash has a mode to allow that, I know my Sony Flash has a multi-flash mode, so you can have several flashes inside one exposure.
Lowering the flash output is often the answer, if they are in close it still works ok and keeps up with the right finger.
As said above, lower flash output. As well as higher ISO settings. One of the reasons you may see multiple flashes is that many (most?_ "modern" cameras/flashes set the exposure by using a pre-flash to measure the output required. Also , a bank of 'togs flashing at the same time (but not simultaneously) will give the impression that might look like one flash firing very fast.
Canon cameras haye a multiple shot facility, 300d about 4, 5d quite a lot. What then is needed is a flashgun with a large storage capacitor and a low power setting. I think I got about 25 on my 5d and Sunpak hammerhead.
