Some work on tonecure in preparation:
- added an rgb norm to
RGB linked channels. The idea is that some enhancements brought by filmic can be applied on tonecurve too. In particular about chrominance control with a norm based on max(rbg). Maybe other norms more or less scientific (more or less creative ?) could be interesting too (like
weighted yellow power).
- added an
LCh independent channelsmode with 3 tabs L (as for Lab) plus C(L) and C(h), letting the user correct the chrominance based on luminance and/or hue.
- added an
RGB independent channelsmode with 4 tabs: L, R, G & B.
All histograms are shown in Lab color space to be consistent with the other modes, even if the tonecurve is applied on a different color space (linear prophotorbg for the RGB modes).
Apart of that histogram issue with log scale is fixed.
Comments are welcome.
