A friend of mine got the Kodak scanner when it first came out. It is a long story
but he has had trouble all the way. Finally today, Kodak said he could return it
and he is ordering the new Nikon. It sounds like Kodak was not really ready for
prime time.
Apparently there is a focusing problem
My understanding as to a short answer is that essentially the gamma curve is
inverse to the curve of the phosphors' luminosity - one is concave, the
other convex. I'm really not clear either, though. I've read a lot but it
hasn't really hit home.

Alright. This mysterious gamma controls the way colors are displayed on the
monitor through some exponential function of some kind. Fine!

In line with shAF's white and black point setting suggestion, there is an
excellent site at http://www.aim-dtp.net/aim/index.htm, very professional
but understandable and lots of how-to-do-its.
There is a monitor calibration section there, and a good walk-through of the

Not to be too picky, but I did mention the issues you bring up in your
first two comments later on in the posting, when I discuss the ALPS printer.
As to point 3, I'm aware how the ALPS printers work. The problem was
that the banding was noticeable when light reflected off the image, or

Ed's really come a long ways with the last few versions of VueScan. Using 6.6.1 I was
finally able to make a scan of one of the slides from the groupscan (the infamous bug

of our vision. Still, extreme care should be exercised, as you say. Usually
