f/stop based false color

[Bill Ravens]

While going over the Lift, Gamma, Gain forum, I stumbled across this reference of interest.

This guy, Kaur Hendriksen, has written a few interesting dctl's, not the least of which is a false color dctl, for Resolve, that defines colors based on f/stops. I've found this extremely interesting to play with to visualize f/stop across a video frame, especially where lighting is critical.

Bill ,

I have a couple of Kaur's DCTLs he's really great at making them.

Someone Else's DCTLs you should look into especially if you are into an ACES workflow is Paul Dore who goes under the name "baldavenger" on Githib. I have a shit load of his DCTL's

Yeah, well aware of Paul Dore. Thanx for mentioning him.

Hey, actually GIOSCOPE is a kind of f-stop based system to evaluate exposure in camera. In color grade it's literally impossible to be certain or precise in regards camera stops because of a number of different curves that can be applied on rec709 transform. Also vastly depends on camera etc etc.

But it's a really great approximation that gives some idea, just don't take this for granted.

Just an FYI...if you're using Gioscope, check out the LUT available, for free, from ManifoldRecording.com. They're developing a false color LUT that mimics the Gioscope, but, in Resolve for Redlog3G10..
