//edit: I've been told to move it to "bugs on mac"
when I batch process several RAW (*.CR2) files to jpeg all jpegs are way too dark. They don't look nearly like the original. When I use the develop persona for each single RAW file instead, the files look almost the same like the original (but also a little darker then the original). This applies only, when all assistants (except for lens correction) are activated prior to processing (View > Assistant Manager > Develop Assistant). If all of these assistants are deactivated, the pictures differ a lot from the originals and are also way too dark - compared to the RAW files (files look like after batch processing).
Do you have an idea, what could be the reason for this? I am shooting pictures only in RAW with my camera and need to batch process all RAWs to jpegs afterwards. For now, I can't do this with Affinity Photo, because each single jpeg is way too dark.
For my understanding:
The Affinity Photo RAW converter should not change the RAW file in any way, as long as I don't change anything while developing (just import -> export to jpeg). Am I right? This is not the case when using Affinity Photo for RAW development - at least for me. The pictures always differ from the RAW file (they already differ after importing. Exporting seems not to be the problem).
sometimes differ slightly: single processing in develop persona with assistants activated.
sometimes differ very much: batch processing or single processing and all assistants deactivated.
When using "Camera RAW" (just import -> export to jpeg) without any changes, after exporting the pictures look exactly the same like the originals (RAW). So the RAW files are not corrupt.

Thank you very much in advance for any hints
