working space: make documentation clearer.

Help
1

Hi,
As I am a beginner, I tried to find my way by reading the documentation. Digikam is a great software, but as a noob, I would like to make it easier to use.

  1. it is not clear how to contribute to improve documentation. I finally ended up here, but I previously created a KDE identity and an account in the KDE Bugtracking system. Please, point to KDE Discuss if it is the right place to start.

  2. in the color_management/working_space.rst, at line 109, there is a See here for more details sentence that has no link. I guess the link is missing.

  3. the same line explain to save files in TIFF format for archive purpose, but previously I read that DNG is the advised format for portability. I think TIFF is not the right format, but please make this paragraph homogeneous with the rest of the documentation as this does not help beginners as me.

  4. finally I exported a RAW file in DNG and tried to process it to achieve a result similar with RAW and DNG. I didn’t succeed with Ansel nor Luminar. So I still consider RAW as the most naive/native format for archive.

Best
