@davidrevoy nice. makes me think that it could be really cool to have blending layers that convert a sRGB pixel to linear via inverse ACES tonemapping, do the blend (add or mul), and then convert back to sRGB via ACES again - this would allow artists to use a filmic HDR workflow for shadowing and lighting without actually needing to work in HDR space
@davidrevoy i have all the formulas here, and have developed palettes with them (see fully automated example pics - input and result). their advantage is that you get kodak style filmic gradients without having to do all the manual work that goes into making a good gradient.
