TIFF files.

oops, yeah. The dpi figure in the above should b e 618. A scan from
a slide I just did read:
2396x3694, 2720 dpi, 0.81x1.36", 19.9MB
Better, eh? :-)

No, it doesn't, it's changed. Interesting, I had never done that -
re-looked at an image on disk with the scanning software. I just
called up an unaltered TIFF. Why is that? Would it help if I cited
the changes? Looks like I could learn something from this. I better
send one through paying close attention to all the settings.
