When working with grayscale images in Photoshop, I’m curious to know how others are setting up their color management.
In general usage of images such as cavity, height, AO, etc. etc. such as in a Substance workflow, one generally sets these to unmanaged as we don’t want any gamma correction on those.
However, Photoshop defaults to assigning a grayscale image a “Dot Gain” profile, which seems more oriented to Print workflows, but also offers Gray Gamma 1.8 and 2.2, and sGray.
My usage of non-color images falls into three basic categories:
- b/w scans of line drawings/equipment plans
- grayscale photographs
- generated CG imagery e.g. again AO, cavity, height/displacement, curvature, etc.
Is there a “best practice” for this in these usages? My hunch is that only the grayscale photographs need a color profile/need color management. Does that sound right?
