I didn't remember exactly what it was about, but I found the post, and it
was about converting to BW:

I appreciate the explanation.

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.
For HSL, yes,
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
are
After playing around with the channel mixer on some pictures, I get an
odd effect sometimes. Just enabling the module with default settings
sometimes affects the picture, the histogram jumps to the left and I
lose detail in the highlights. Seems to happen when I also use filmic
RGB. Is this
