Excellent posting Bill. Pity I don't scan slides nor print my scans.
Still, insightful.

I have done this in the past.
It occurred to me this week that this is not the right thing to do (I was
looking at some slide-scanning samples I've published on the web and
thinking about their colour). Because slides are designed to be viewed
using lighting of 5000-5500K (as far as I can tell).
Windows users normally have a monitor defaulted to 6500K (or with Dell
monitors 9300K for some reason - gah!!!). I have my PC "calibrated", using
Adobe Gamma, around a 6500K target.
Frankly, I dislike monitors calibrated for a 5000K white point. I find I
can "see" it. Strange, as human perception is supposed to be fully adapted
for the range 5000-5500K (or thereabouts). I really don't know why 5000K
disturbs me. I have the same problem with monitors set to 9300K. I never
adapt to it. But I expect that.
Anyhow, if you have a Mac, your system is probably calibrated around 5000K,
as far as I understand it. So the "slide against the screen" trick should
be more truthful.
