I've just looked at the new 50MB scan, very noisy with some vertical
banding. The scan is much too light, with the histogram showing no blacks.
Can be easily corrected but some detail lost in the highlights of the scan.
They probably thought my trannie was too dark but it is of a swan, the swan
is correctly exposed, so the background has gone dark.
I did the test and saved the image as a jpeg with 7:1 compression (level 10
in Photoshop 5.5). I did a difference and the image came out black, showing
no difference between the bitmap and the jpeg. I'm very very surprised and
impressed at the quality jpeg. Although not enough to save my scans as jpeg
obviously :-)

It's a fair point, but might just mean that the manager on the sales desk
doesn't know too much. The back room technician doing the scans may - in
fact
if the scans are any good, he can't be that clueless (as we all know:).
