I should add that 43 megabyte is not very high resolution at 24 x 36.
What Shel cites here -- 180 met, 8 bit -- is much more appropriate for
a print of that size.

But it's not a 43mb TIFF - it's a 6.5mb JPEG. How does a small JPEG

Converting it
back to a TIFF won't help it - or will it? In Bob's case, all he
shoots
are JPEG's, so the info was never there in the first place. Plus, the
file
he provided was a panorama that was stitched together from, IIRC, three
separate files, each being (if my math is correct) a JPEG of only
about 2.2
mb. IOW, even though the file was 6.5mb the information it contained
was
about like a 2.2mb JPEG ... does that make sense?
In my case, the file starts out as a 16-bit, 120mb or more TIFF, and
remains so throughout the editing process until converted to an 8-bit
file
just before being printed. Had I stitched together three files, as Bob
did,
the total file size would be closer to 180mb.

Bob's file was a jpeg - 5000x3000 pixels (as he mentioned) is a
pretty decent-sized file. That'd be 43Mb as an 8-bit tiff.
