OK, so PNG might be a contender. Next question then is how do I
convert from TIFF to PNG? I would like to automate this also. None
of my software does 16-bits/channel (remember, no Photoshop). Does
Image Magick support 16-bit/channel TIFFs and do TIFF to PNG in 16
There's an ImageMagic user forum, I believe, where you could post that
question directly. http://www.imagemagick.org/

IIRC, the last time I looked at ImageMagick for Windows, they had 4
different packages available, 2 that did 8-bits/channel and 2 that did
16-bits/channel. Pick the right one and use it, no problem.

Nobody can "vouch" for the viability of PNG or any other format. You
understand that, right? Ultimately, we're all just guessing and
taking our chances.

Er... huh? There are a few image formats that are fully described and
have reference implementations available in C. TIFF, PNG, and JPEG are
all formats like that. libjpeg, libtiff, and libpng are all under a
BSD-ish license, so any programmer who's competent can build an app to
convert a raw bitmap <-> {TIFF,JPEG,PNG} pretty easily. So formats like
those are future-proof as long as competent programmers still exist.
(rafe b was probably thinking as a user, not a programmer, though.)

If you store images (or any data, really) in a format that's not Open,
you will eventually lose that data. People have been saying this for
the last 10 years, but the vast majority of users haven't grokked it
yet.
