@JordanSzubert Andrew misspoke. The basic maths are basic maths and hold up.
Read the AdobePDF specification 1.7 and look for 1.0 in the blend mode formulas.
Anything with a 1.0 is display referred and will break.
@JordanSzubert If you really want to be an asset to the community, start a wiki page where you gather all of the broken or awkward nodes. There are many pinch points lingering around that no one really saw.
@JordanSzubert I would guess 85% of the blend modes have been broken forever.
maraCZ brings up an interesting point - if you don't have any noise in your images (which in theory is the case for a 3D render), how on earth do you even measure dynamic range. it becomes infinite.
@troy_s so then how do you come up with a dynamic range figure for filmic blender? Just curious
