Hi, I've been using AffinityPhoto to process raw files from my Nikon D7500 for over a year now, and today for the first time I've faced very strange issue. I took few night photos of a stone gate highlighted with violet light. When opening the file with AffinityPhoto I observe some pinkish dye and lack of smooth tonal transitions. The image is displayed properly with Nikon NX Studio and using MacOS picture viewer. In AffinityPhoto I managed to get rid of the pinkish dye after playing with 'RAW output format' and 'Tone curve' settings in Develop Assistant. But I cannot get smooth tonal transitions as I can see it in NX Studio. I attach screenshots below. If that is important, I work on Mac Mini M1. Do you have any idea how to display these raws properly in AF? AffinityPhoto (version 1.10.5) NX Studio
