This is just a proof of concept.
Owners of monochrome cameras like a Phase One or Leica might profit from it. The process consumes a bit more time than simply using Negative Lab Pro, which is not needed for it anyway. In order to get some extra hurdles, I tried the process using my worst lit (mixed low light, underexposed) negative.
I used/did the following items/things
- iPad as a backlight - with three images, one red, one green, one blue
- Camera scanning setup
- Photoshop (and Monochrome2dng)
- Scan the negative, one shot per red, green and blue backlight
- Simulate monochrome camera: Convert the shots to monochrome with Monochrome2dng
note: this step is not necessary for people with monochromatic cameras - Invert and convert the 3 monochrome DNGs to 16 bit TIFF and add to Photoshop as layers
- Premix image - lower % for R and G layers
- Add curve and colour balance layers and work them until the result is close to what you want
- Collapse layers and export
Caveats
- Keep your setup untouched while taking the shots in order to prevent misaligned shots
the result I got looks like polaroid autochrome when pixel peeped, Probably due to step 2 - I’m not that good with Photoshop, others might get better balanced results
- I also shot CMY instead of RGB, but have not yet processed that lot
