Ah yes. And the wonderful times where people embed an image into Word,
but rather than resize the image then embed it, they insert a 50Mb TIFF,
then just resize it within Word, and wonder why their machine crawls.
Then, to add insult to injury, they try to email it to someone....

We had an experience where we were collecting passport type photos of
people. The member of staff assigned to do this scanned the images from
hardcopy. Explicit instructions regarding sizes were given. I was not
amused to find that the final product of this persons labours was a
directory containing some 50 or so .doc files, each with an embedded
image, and that the JPEGs had been deleted as soon as the word doc was
created, so we didn't even have them on the backup tapes. Aaarrrrgggh.

Most of the interest I've seen in 16 bit mode comes from people wanting
to exploit the 12bpp data that many cameras save in RAW mode. So I'd
have thought that 12 bit would be enough to satisfy most users.
