I sent a different set of files of to Gammatech to be put on
120 film. This time, I started with a sharper original,
pushed the color saturation a little, and sent 3872-pixel
square image pairs rather than 7744.

As predicted, I can't really detect the decreased resolution
in the final output. What I notice are some rivalry in some
segments of ice and a very noticeable flatness to water
reflections. I attribute both of these to shortage of
information from the scan as well as to subsequent
resampling operations. It will be interesting to see how the
water reflections of an 1800dpi scan compares to that of a
downsampled 2400dpi scan.

Please note that when I say I can't detect the decreased
resolution, I mean, "The 3872 image looks about the same as
the 7744 image." I can certainly tell the difference between
the original and the scan/film-recorder duplicate.

Ok, so who are the best companies to send digital files too?

Has anyone had success up scaling from realist?
