Re: Light box screen match
Re: Light box screen match
The monitor's are Eizo CG210 and are calibrated to 120 cd/m^2. I
know they
can go a bit higher (I've achieved a max luminance of about 180 cd/
m^2), but
Eizo docs state that above 120 the color reproduction isn't
guaranteed. Even
so, at 180 I'd still have to lower the light box to about 25% of
1270 (which
is 317.5 and is still greater than the monitor) and at that level,
which is
the same setting that I've been talking about, the "transparency"
is too
dark.
Stated another way, the concept of dimming the light box is so that
you can
match viewing conditions and make a valid comparison. I'm proposing
that
this makes no sense because the dimmed light box introduces a viewing
condition that would never be used. Why would I want to generate a
screen
match to an image that does not appear correct?
It seems that an image on a display that is quite bright should be
bright
enough for taste &/or printing.
True, unless the reference image that is being matched is not
viewed with
the proper viewing conditions. In that case my bright screen will
still have
a dark image on it. I don't think the brightness of the screen will
really
solve the discrepancy. Even if I had an HDR display as was
suggested, this
is not the correct solution either because at some point that image
will
need to appear correctly on a regular display and on printed output.
As I said in my first message, I believe the only truly correct
solution is
to use a color appearance model to account for the different viewing
conditions. But short of that, I was hoping that others might have
dealt
with this somehow using currently available tools without relying
totally on
manual editing.
Would it make sense to work in a standard color space and then
repurpose the image for TX production or print or web? Maybe profile
a TX in/on the lightbox, and use that as the destination when going
from standard color space to TX with BPC?
I wouldn't care to sit in front a display pumping 1270 cd/m^2!
