I started printing some of my photos, but this has led me along a path where I don't know if I'm doing things correctly and they ask me questions about which I don't know the answers. Here it goes:
- I use Ubuntu (18.04), Darktable (2.6) and Gimp (2.10).
- My photos are taken in the "Adobe RGB" color space. I have put this option in my two cameras.
- I have used Agryll to calibrate my monitor in color with a Spyder 4 Elite. The Agryll profile is installed on the entire system (on my desktop, I choose the settings -> Devices -> Color and see the profile installed for my monitor)
- When I work on an image I intend to print, I choose "Adobe RGB" in "output color profile" in Darktable.
- When I export the image from Darktable, I choose TIFF, 16 bits and "Adobe RGB" as a profile.
- When I import the images into Gimp, Gimp asks me if I want to convert the images to sRGB. I say no, since Adobe RGB is better.
- Once I finish my work, I save the image as TIFF again and take this to where I want to print it.
- The reason I want to save it as TIFF, 16 bits, and in Adobe RGB, is to have more color and more information in the image, because the person (s) who prints the image often works on the image (in cooperation with me) to do it right.
So, my questions are:
- Do I not need to install any profile for my monitor in Gimp or Darktable, because both Gimp and Darktable (by default) use the entire system profile? Without the need to configure any settings in Gimp / Darktable?
- Is the previous workflow, with the use of 16-bit TIFF and "Adobe RGB", the correct way to get as much information as possible in the image along the way?
- When opening the TIFF file in Gimp, why does Gimp ask me to convert the integrated profile to "sRGB"? My understanding is that "Adobe RGB" is better?
- Is there anything I should be aware of that I haven't mentioned? Or something I am missing? Like some configurations and Darktable / Gimp should I configure or verify?
