When the “cameras absolutely do not have gamuts” quote moves from “some
response” of a camera to “color accuracy” I get lost. It sounds as though
there is a ruler(the display) measuring a non-dimensional entity for accuracy.
The quote seems to assume that the camera has infinite perfection but it’s up
to some mysterious other entity to prove that it doesn’t have infinite
perfection.
I’m now losing my fight to understand - I was pretty much following the
previous threads about the distinction between color and numbers but this curve
ball has me swinging and missing. I believe the quote was supposed to bring
some clarity but it didn’t work for me. Maybe there’s another way to explain
not having a gamut that will help.
