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 turn
into a larger TIFF file containing more information?  Once a file is a
JPEG, the information it contained as a TIFF or PSD is gone. 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.
