Lossless Format for B&W Scans

by user379468   Last Updated August 13, 2019 21:18 PM - source

I will be scanning a number of old black and white photos from both medium format and from glass plates. I'm wondering what my best bet is for digitizing and archiving them. So I suppose it's a 2 part questions.

  1. are their guidelines around the maximum resolutions that you would scan medium format ( or glass plates ) in, I would assume beyond a certain point it is pointless.

  2. What format is best for archiving, Raw, Tiff, PNG I would assume that discarding the colors from the profile would make the photo smaller, is there a certain color profile that is best? is their eve na way to save a digital photo with only greyscale data ?
