I recommend that fax group 3 and 4 images *always* be labeled
MINISWHITE. If you have an application that writes MINISBLACK in this
case, fix it or do not use it to write TIFF images. Many applications do
not correctly handle MINISBLACK with fax compression.

If you have existing MINISBLACK fax images, they probably cannot be
fixed by changing the photometric label. They images need to be
inverted, then recompressed and labeled MINISWHITE.

Of course, you can get away with MINISBLACK if all your applications
handle it correctly, but it sounds like that's not the case.
