With my Canon 580Ex the slowest flash duration is 1/1000 & it goes up to 1/35000 at 1/128 power - see this link Canon-580ex-flash-duration |
How fast would onboard flash be in order to freeze motion? Also, I just ordered a Newer TT560 which has different power settings and wondered if that would do the job as far as freezing water drops etc.? Thanks.
