It's great having zebras to help get proper exposure. I'm from the old school where you could set video cams with zebra settings at different levels on settings 1 and 2. I found the global draw menu where you can have different items be displayed with each press of the info button (60D) but I can't figure out how to set zebras so they'll appear say on preview 1 @ 75% and preview 2@ 95%. Is that possible? When I change the value on one display it changes the value on the other.
Yep that's a limitation of ML. It can be fixed in theory
