DOCUMENTATION

This code ports :

  1. Troy Sobotka's filmic curves for Blender (and other softs) https://github.com/sobotka/OpenAgX/blob/master/lib/agx_colour.py
  2. ACES camera logarithmic encoding https://github.com/ampas/aces-dev/blob/master/transforms/ctl/utilities/ACESutil.Lin_to_Log2_param.ctl

The ACES log implementation is taken from the profile_gamma.c IOP where it works in camera RGB space. Here, it works on an arbitrary RGB space. ProPhotoRGB has been chosen for its wide gamut coverage and for conveniency because it's already in darktable's libs. Any other RGB working space could work. This chouice could (should) also be exposed to the user.

The filmic curves are tonecurves intended to simulate the luminance transfer function of film with "S" curves. These could be reproduced in the tonecurve.c IOP, however what we offer here is a parametric interface useful to remap accurately and promptly the middle grey to any arbitrary value chosen accordingly to the destination space.

The combined use of both define a modern way to deal with large dynamic range photographs by remapping the values with a comprehensive interface avoiding many of the back and forth adjustments darktable is prone to enforce. Note : we use finite-math-only and fast-math because divisions by zero are manually avoided in the code fp-contract=fast enables hardware-accelerated Fused Multiply-Add the rest is loop reorganization and vectorization optimization

Now we have 3 segments :

  • x = [0.0 ; toe_log], curved part
  • x = [toe_log ; grey_log ; shoulder_log], linear part
  • x = [shoulder_log ; 1.0] curved part

BUT : in case some nodes overlap, we need to remove them to avoid degenerating of the curve

The log2(x) -> -INF when x -> 0 thus very low values (noise) will get even lower, resulting in noise negative amplification, which leads to pepper noise in shadows. To avoid that, we need to clip values that are noise for sure. Using 16 bits RAW data, the black value (known by rawspeed for every manufacturer) could be used as a threshold. However, at this point of the pixelpipe, the RAW levels have already been corrected and everything can happen with black levels in the exposure module. So we define the threshold as the first non-null 16 bit integer
