Well, Stephen, thank you for the very thorough discussion. It is
appreciated, although I am still a bit skeptical. I have no problem
with the 6500K monitor setting. I prefer it myself because it seems
more neutral. Turning around and looking at the print in a different
temperature light to evaluate my success in printing is still counter
intuitive and I wonder whether it is just that there are not 6500K
booths and lighting available because the printing industry
traditionally uses 5000K. Maybe just a description of practices rather
than the best way to do something?
And if the eye is so adaptable, then probably none of this color
temperature business matters, does it? I kind of doubt that because I
have made prints that have looked just OK in normal household lighting
with a mix of incandescent and daylight from windows that looked just
stunning in a different light. And the brightness of the light makes a
difference too. Brighter is usually better to me and evaluating a print
in "subdued 5000K" light would seem to add another hurdle.
Lots of new mysteries to explore. Thanks again.
