I have a Sigma dp2 Quattro, and I'm experimenting with Affinity Photo as an alternative to my current Sigma Photo Pro -> TIFF -> Pixelmator workflow, mostly because SPP is both very slow and not Apple M1 native.
One thing that the dp2 can do (and why I bought it in fact) is make B&W-preferred raw files. As far as I can tell these are just colour raw files but they have a flag set that says 'this is meant to be B&W'. SPP then knows about this and shows you the file in B&W unless you go out of your way to see it in colour. This workflow is important to me as a mostly-B&W-film person: once I've seen an image in colour I find it very difficult to then see it again properly in B&W, and what the dp2Q & SPP let me do is never see the image in colour.
If I look at B&W-preferred X3Fs in Affinity Photo they appear in colour by default. Is there a way of saying to it that 'if the B&W flag is set in the raw file, do not show colour unless you are told to do so'?
Thank you, and sorry if this is a FAQ: I did look and could not find it.
