I can't find this info anywhere on the Nikon web site.

If I scan an image full-on highest res, 16-bit color depth and save to
a lossless format (TIFF?) how big will that file size be? If I scan a
B&W neg, will the file size be 1/3 of the color file size?

Thank you.

Filesize for uncompressed TIFF is the about same as the Image size(of the
film) times the Resolution times number of colors times 2 for 16 bits.

For 35 mm film 24X36mm, (0.945" x 1.4")

Short size = .945 * 4000=3800 pixels
long size = 1.4 * 4000= 5600 pixels.

3800 * 5600 = 21,280,000 * 3 *2= 127.68 MB for color at 16 bits.
B & W would be 42.56 MB for 16 bits.

In actual practice on my LS5000ED this is very close. I typically find
them *slightly* larger than the calcs predict at a tad over 128 megs.
File sizes do vary but only a little.
