Thundercracker- unfortunately, at the moment, i have no suggestions for optimal usage. Truth be told i only rediscovered the histograms today. Just to compound matters, i`ve deleted my original scripts (annoying, since i`d written a script that put all different versions side by side for comparison). It`s getting a bit late here in england now, but what i`ll do is this; when i get home from work tomorrow, i`ll write up a quick batch of scripts to replicate the side by side comparison , so that people can a least see what each histogram does to each video and see which produces the desired effect for each scene, and i will post these into the "please help me with histograms" thread in the technical discussions board, since that seems the right place to continue this. I`ll also prat around with a few things that i want to try. The basic scripts will be posted tomorrow evening (english time), when i`ll probably have quite a few notes to go with them.
