I have been trying to improve my B&W prints. Toward that end, I have two question:
(1) Assuming I output my raw conversion, which is made B&W as part of the process, as a 16-bit TIFF, would it be better to use sRGB or Adobe RGB as the color space?* In other words, does Adobe RGB have a wider ranger of neutrals that it can describes, blacker blacks and/or whiter whites?
(2) If I then import that TIFF into Lightroom for printing, will it almost always be better to print with perceptual rendering intent, instead of relative colorimetric (which I usually prefer for color photos)? My sense is that relative colorimetric has crushed the shadows in some of my B&W photos, and in a couple of experiments, perceptual better preserved shadow detail. But maybe I'm missing some relevant considerations.
Thanks!
* I often use DxO PhotoLab with DxO FilmPack. DxO's internal working space, at least in the older Optics Pro, was Adobe RGB, so outputting to ProPhoto RGB seemed pointless. Also, since the TIFF will already be B&W, the only consideration is how well the color space represents the range of neutrals.
