Photoshop 5 (and to a lesser extent Photoshop 4) can read 16 bit TIF files from those scanners that are able to create such a beast, but usually, these files are tweaked and then written down to the more usual 24 bit version. Just because a scanner can read 30, 32 or more bits, doesn't mean that you end up with an image file with more than 24 bits, and doesn't mean that you need more than 24 bits in the final output file.
