OpenDRT v0.0.82

[jedypod]

Features

• Add input transfer function options with common camera log and log working space encodings for the Resolve DCTL.
• Add Blackmagic Gen5 colorscience inputs: Blackmagic Wide Gamut // Blackmagic Film Gen5 Log encoding
• Add lenscap black subtraction compensation feature. Pretty experimental but it is intended to add a small value to compensate for negative grain on input. Since OpenDRT maps 0.0 to 0.0, this helps preserve shadow detail. Disable this if manually compensating black levels while grading.
• Add gamut compression operator to better handle extremely high purity input colors.
• Update perceptual dechroma to use ICtCp colorspace. This biases the chromaticity-linear hue paths of the highlight dechroma and gamut compression, along perceptual hue-lines, resulting in more natural looking colors and better appearance matching between HDR and SDR outputs.

Hi Jed. Ever since I read up on Troy Sobotka's Filmic Blender I completely fell into the rabbit hole of colour management. It's horrible here, but very fascinating! I've been reading the wonderfuly nerdy thread on ACEScentral with awe.

I was wondering what is needed to create an OCIO config for OpenDRT. Is there any chance of getting this into Blender, Affinity Photo or other DCC packages?

Hey @clausbertels, thanks for the comment! Yes I've been in this rabbit hole for quite a while now and I don't think I'll be getting out anytime soon haha!

Your comment has good timing, I was actually starting on putting together an ocio config with opendrt this afternoon. It's been on my todo list for a long time, I just keep getting distracted by more interesting problems. It's not hard to do, will just take a bit of time. I created an issue here so we can track progress.

Stay tuned!
