Fist of all: Thanks to all for that positive feedback and all the brave folks who tried my G-Log profiles. After gaining more understanding what the “color depth” actually does, here are the new profiles for G-Log (1.1).
JUST DID A MINOR UPDATE – Version is 1.2 now
“Color Depth” is quite misleading, since most guys think, it has to do with color saturation (I´m also guilty of that mistake).
That´s not the case as anyone with a vector scope can see – it should be called “Color Brightness” or better “Color Gama” cause that´s what it does.
The next confusing thing is, that the numbers are somewhat backwards.
Smaller numbers make colors brighter and higher numbers make colors darker and more sturated.
So If you want to keep red from clipping, you have to dial it all the way up.
The basic Black level is Zero. For best results, adjust your Black level frome scene to scene, so that it lands a hair over 0 IRE, to avoid posterisation in post.
As before,
G-LOG A: Looks deep into shadows
G-LOG B: Is a bit more on the conservative side.
G-LOG A 1.1:
Black Level: (basic) 0, (controlled = variable)
Gamma Standard
Black Gamma: middle, +7
Knee: 80, -2
Color Mode: ITO709, +8
Color Level -2
Color Phase -7
Color Depth: R+4, G 0, B+4, C+5, M+5, Y+5
WB-Shift: LB-5, CC+2
Detail 0

Make sure you set your highlights between 85 and 90 IRE on G-LOG A.
G-LOG B 1.1:
Black Level: (basic) 0, (controlled = variable)
Gamma Cinematone1
Black Gamma: High, +7
Knee: 90, +2
Color Mode: Cinematone2, +8
Color Level -2
Color Phase -7
Color Depth: R+4, G +2, B+5, C+5, M+4, Y+5
WB-Shift: LB-5, CC+2

Thanks Frank will give this a test. Used G-Log A on a recent shoot that’s currently being finished off. Worked out well.
Did you make any progress with the LUT for the G-Log profiles?

I think we have a winner good sir! Solves the issues I saw with the other version.

I’m seeing a lot more saturation and depth in color, but less leeway in dynamic range. Anyone else seeing that? Seems a little too saturated out of the cam.

Yes here same issue to much saturation, and some artificial LED lighting make it all overexposed. I will stick to version 1 which i really liked

Awesome Frank. I’ve been loving G-logA for my projects. I’m also very interested in a LUT for color if your developing…
