What do you need TIFF files for that PNG can't

I'm genuine interested; there are things the TIFF format can do that PNG
can't, but I'd like to know which features you need and why.
I'm not sure of all the technical details, but see the Wikisource discussion
at
http://en.wikisource.org/wiki/Wikisource:Scriptorium/Archives/2006/11#TIFF_….
From what I understand, PNG's aren't all that
great for photographs (or in
the Wikisource case, scans of pages of books and other
documents) and don't
work well with scanset, and JPEG's are ridiculously large for the same
amount of information as is in a TIFF. Discussion on Commons (
http://commons.wikimedia.org/wiki/Commons:Village_pump#TIFF_files.3F) seemed
to suggest that the real problem was image size, but again, it looks like
JPEG's would end up being bigger than the TIFF's.
At the end of the day, we'd like to be able to store large images that are
as detailed as possible, and be able to use them for proofreading on
Wikisource.
