I always think TIFF is over killed if not for archival purpose, try to
save your TIF to JPG in Photoshop with compression 9 or 10 (in 5.0) or
10-12 (in 6.0) open them both and view them at 100% (or even 200%) see
if you can find the different. I bet you can't but for the file size
you can save 70-80%.
If your file has properly trimmed histogram, you also don't need 48
bit. Your output device (and you eyes) can't identify the different.
