marshall rose Posted April 18, 2012 Share Posted April 18, 2012 Im lighting tabletop with various jokers and litepanels. For some shots I need to shoot with my shutter at a 250th of a second or a 500th. When I use the lightpanels i don't get a strobbing effect (or at least a rolling bars effect) when shooting with narrow shutter. When I use the jokers I do. Sometimes I need to use the jokers depending on the situation. So anyway, whats the solution here? I've put the shutter in "angle" mode but i still can't find the exact right shutter speed to avoid the rolling bars effect. I know jokers need to be shot with shutters that are divisible by 3 or 4 cause the voltage frequency is 120, right? Anyone know a shutter angle i can use that gives me an exposure of about 250th and also one near a 500th that won't give me rolling bars when using HMIs? thanks Link to comment Share on other sites More sharing options...

Anything over 96 / 100 fps can be problematical & you need to test what exactly works in the exact situation. Link to comment Share on other sites More sharing options...
