Hi - I'm scanning B&W negs from a flatbed in 16-bit using Silverfast, and saving them as jp2.

Opening them Affinity Photo results in a warning that it is being assigned an RGB profile because none is assigned; the resultant image is B&W noise.

What am I missing?

Yes - I realized that Silverfast has a config option to add one of a couple of grayscale profiles to the file. So, tried that:

TIFF no profile: AP adds a D50 profile and the image looks good

TIFF w/profile: AP uses the profile and image looks good

JP2 with OR without profile: assigns RGB profile and image is random

Example with generic gray 2.2 profile attached.

AP v 1.8.6

Thanks!
