I have been using Darktable for processing of my medium format C41 negatives using an Epson V800 and Vuescan. I use the image mode and scan to a raw (gamma 1 tiff).
I’m trying to figure out what the best input color profile to use for further processing. Using Rec709 linear seems to give me the exact look of the scanned negative, but the colors seem a bit dull (Kodak Ektar/portra film stocks).
If I use rec2020 linear, it seems the colors need too much correcting for the red level in the correction module.
I am using the color picker for the film base before any further processing.
If the entire negadoctor module is only optimized for DSLR scans, then I can look for some other software to process these as I am not interested in scanning that way.
Some information about the system and version being used:
System76 Thelio (Pop_OS 21.04)
Darktable 3.6 built to use the OpenCL (AMD GPU 5700)
Thank you for any assistance.
