Heyo, I am having an issue when converting my b&w negatives. It has been happening for awhile and I haven’t been able to edit black and white photos properly making it difficult to enjoy shooting. After the conversion all my images seem to have a yellowish cast. I ensured that the color model is set to “B+W” when converting. Additionally mids, highs, and shadows are all zeroed out and I have pressed the reset button. I’ve updated and reinstalled lightroom/NLP. I am at a complete loss for what is going on. I’d appreciate any insight to this, it has been very frustrating.
What happens if you click white balance picker on any light gray surface? if picture becomes completely grey with no coloring in highlights and shadows i would just do WB and move on. You may examine the shape of Tone curves to see if you can observe some interesting pattern. all rgb curve should be very similar, but in your case they seem to be offset slightly
I have B&W negatives shot on Ilford XP (and similar type of film) which were not B&W.
If nothing else helped, I desaturated the images before proceeding with other settings.
