So for many of us less technically proficient readers out here, is
it suggested that we should ALWAYS use the D50 setting and NOT the
D65 setting when creating our display profiles? For some reason I
thought I recall
reading in another discussion that the general trend now is
calibrate all displays to 6500 degrees (D65), NOT the graphic arts
standard of D50. I'm a little confused.
Well, at least in this thread nobody said you should always use D50;
the point that you probably refer to is a technical one: version 4 of
the ICC specification says that in ICC profiles, *internally* values
should be stored relative to a D50 white point, so that using white
points other than D50 means the values must be transformed before
they are written into the ICC profile. This is like defining the
origin of a coordinate system and not a recommendation for actual
settings.
Second question, should I be using the "native white point" of my
display, as I've heard many suggest,
Others in this list are much more experienced than I am; all I can
say is that at least using the native white point does not solve the
inconsistency issues I'm experiencing, so this wouldn't be a reason
to stick to it.
Bye
