| generally speaking, slower is better, but most cameras won't shoot at a shutter speed equal or very close to the FPS rate... some do. 1/25th won't work at 29.97 but some cameras will do slow shutters. ok for static B roll, but probably not good for most shots. ya at 1/100th you certainly risk getting phased at the dark side of the light pulse ( that sounded SOOOO trekie :) ) but you can flip the camera on / off or change the shutter up down to try to get to a better spot in the cycle. 1/50th is generally the best place, but sometimes 1/100th works better. just have to try it and see. s On Feb 14, 2012, at 10:58 AM, Jim Curtis wrote: > I think you went the wrong way, Steve. An exposure of 1/25 of a second would guarantee up to two full cycles, whereas 1/100 could fall in between every other cycle and produce darkness, presuming a square wave light source that's on for 1/25 of a second, and off for 1/25 with no lag.
