I am often asked to evaluate color under incorrect lighting conditions.
Most of the time, I can convince whoever is asking that this is a bad idea.
Sometimes, however, I am evaluating two images printed on an identical
medium; for example, a "before and after" demonstration of a color
correction on the same photographic paper, or two identical prints at
two different sizes.
I have always argued that these should still be evaluated under balanced
lighting conditions, but invariably someone says something like "but if
the color is off, it'll be off in the same way". I don't believe this
and my experience shows otherwise, but I have a difficult time
explaining why.
Could someone please give me a concise (I hope) way to explain this to
people? Or am I wrong, and it really doesn't make a difference?
Thanks!
John MacDonald
