Although I used them on very few of my photos, I used to enjoy playing around with toning presets like Cyanotype, Sepia, and especially Old Polar, in LR. Is there a free program that offers something along these lines for RAW files, or even TIFFs and JPGs?
Alternatively, can someone direct me to processing formulae that will yield the same effects?
As mentioned you can use colour lookup tables (LUTs) to emulate the colours (and to some degree the light) of film. I use the LUTs provided by RawTherapee, and Iām very happy with the result:
Important: If you are using Darktable I strongly recommend moving the LUT module to a position AFTER Filmic RGB (or Basecurve if you use a legacy workflow), but BEFORE the output profile module.
