Depends on the scanner used.

The Agfa Horizon Plus A3 scans in three passes, for each pass it uses
another separation filter. The filter holder however has 4 filters, the
fourth filter is used when the scanner scans B&W in one scan. It probably is
just a ND filter. For an old 1200 ppi scanner the quality is quite good, and
usable up to 11.5 x 16.5 " filmsize.

The Nikon LS 8000 that I have next to the Agfa has some flaws in its
NikonScan software, any negative scanning mode clips in the shadows. It then
is better to scan in positive and reverse afterwards.
