Dear everybody,
I’m going to take images with my XT-2 with the 23mm F2 lens with a IR72 filter (infrared filter) of Hoya installed.
I ’ am searching for a good workflow in Darktable to convert the infrared RAF files in to B&W Jpeg’s…
Please let me know where i can find the information (instructions) needed. Or does somebody has experience with it in Darktable and send me his workflow.
Much appreciations upfront.
Greetings.

Hi Claes,
I did not found any ready made workflow.
So after some trail and error I do have the following workflow

  1. Compress history stack to “original”
  2. Use “input color profile module” and choose “Linear infrared BGR”
  3. Use " color contrast module" put both slider to at minimum 0,25 or lower (does give a shift on the colors.
  4. Use “filmic module” to my liking
  5. Use " equalizer module for “clarity” and “sharpen” the image
  6. Activate " Velvia module" to my liking
  7. Use White balance and choose “spot” this makes the image almost " B&W"
  8. Activate " monochome module"
    And we have our infrared B&W images.
    See two examples Do You like them?

Yes, I do!
I like the top one better – sort of more distinct?
