Digital BW, The Print

Ernst,

I agree that it is the level of illumination for both screen and 
viewing that is critical, not the temperature.  I have stayed with 
D50 for reasons already stated (it is at least closer to typical 
viewing temperatures) but I have adjusted the monitor luminance to 
match typical viewing luminance.  Standard (ISO) luminance for 
viewing graphics is considered to be 350-500 lux (critical viewing is 
generally accepted as 8.5 lux).  So I view prints initially at D50 
and about 400-450 lux (but I then walk them around the house too).  I 
have matched the monitor appearance to the print thus viewed.  In 
calibrating the monitor, this comes out to a setting of about 50 
cd/m2.  This figure is lower than generally recommended monitor 
luminance, but I am viewing the monitor in a dimly lit room. I 
believe that many monitors will not allow such low figures, but the 
LaCie 321 I'm using will go down to about 40.  Higher luminance 
settings on the monitor (even 80 or 90 cd/m2) represent the image as 
brighter, contrastier and crisper than the final print. This setup 
has been working quite well for me using Roy's ICC profiling 
approach.  The screen is very highly predictive of the print and the 
relationship between screen and print is almost perfectly consistent.
