I will have to dig through my Pixls posts to find this, but I posted about
a problem using channel mixer, and I received that suggestion in reply. I
tried it, and it fixed the problem as far as I could tell. I will see if I
can find it tomorrow.

Try moving channel mixer above filmic rgb in the list on the right side.
Ctrl+Shft+right click on channel mixer module. Then move up the list. I
sometimes have trouble getting it to land exactly where I want it to be, so
if it is not where you want it, move it again.

If you stick to "graymode" or the color modes (outputs R,G,B) it should be
fine: there is a bug that clips large signals to 1, which is really a bug
but has potentially been incorporated in many models. Certainly if you keep
the sum of values to 1, it should rarely cause a problem.

The problem is that the channel mixer has a clamping function which limits
the values that are allowed to pass through. This is not appropriate
behaviour for the scene-referred part of the pixel pipe, as it can result
in exactly the symptoms you report. The devs are aware of this, and there

The channel mixer in dt, as it is in Raw Therapee and GIMP, is a GUI. What
you need to understand is mixing. Here's a video that has the use of
channel mixer at the beginning of the editing.

The channel mixer is basically 3 modules in 1:
- using the red, green and blue destinations, it allows you to effectively
do a matrix multiplication on the [R,G,B] vectors:
[Rout] [Rr Rg Rb] [Rin]
[Gout] = [Gr Gg Gb] x [Gin]
[Bout] [Br Bg Bb] [Bin]
You use the sliders on the red, green & b

I have tried to use the channel mixer module, but I don't quite
understand it. I have only been able to effectively use the presets.
I have read the user manual, but it didn't help much.

The histogram in "levels" is showing what that module is seeing as input. The

Hi,
Tobias said,
"Regarding the problem with the '.', it seems that for some reason the focus
indeed is first passed to the parent window instead of the popup directly. I
suppose other keys (like, numbers) are working when typing?"
Just to add some informations:
I use quite often this module and
he manual. Then, those of us who
cannot do this ourselves (well...probably only me!) would, at least, have
access to those film type emulations.
