Still no black and white profiles 
but I hoarded some more BW datasheets, and I will start hacking the pipeline for this soon. I didn’t design the program abstract enough to make these changes easy. I have another dense week at work, but after that hopefully more spare time and brain space to try new things! 
If you mean this Embrace the noise! - #20 by arctic, it was some early experimentation with adaptive grain, that I never really finished or shared. Conceptually it is not too far from one sub-layer of the grain engine here. It was a simple script, without density curves, I should still have it somewhere.
