A working draft of the upcoming ISO 12646 (soft proof comparison of
screen to print) recommends at least 100 cd/m2 and should be more than that.
I had excellent match between the Cinema Display 130 cd/m2 and some of the
viewing booths I reviewed for an upcoming PEI article. The Cinema Display's
higher luminance level necessitated less compensation [dimming or dumbing
down :) ] of the light booth to balance with the screen's perceived
illumination. Luminance level does not effect your shadows it just
increases your dynamic range from black to white. Personally, I think a
bigger dynamic range is ideal. The bunk floating around about pushing the
luminance level will prematurely age a monitor is a myth. I have been
running an old Lacie 21/108 for several years at 100 cd/m2 and am still able
to hit that target luminance level even with the monitor on every day --
sadly, I still work weekends :(
