But it is my feeling that the room where you compare the print to the image on the monitor should also be close to "normal" light levels so that your vision will have other references to standardize on.
But what is "normal?" and how could this affect the process that is most critical, editing the image?
The higher the luminance by the display, the more it affects the perceived contrast ratio as any ambient light hitting the display affects its black. In such a case, lower is better, to the point that you can't go too low until you rip open your leg by bumping into a table!
We have to accept that we may not have any idea where the print will reside. And we have to realize that all ICC profiles assume a viewing condition of D50 (unless we have a high end package like ProfileMaker Pro, go out and actually measure the illuminant and build that into the profile).
None of this is prefect. But as Mr. Schewe would say, it beats pissing in the wind. At least setup an environment whereby you can view a print and the display such that you have a close match.
What do you do when you have to print a 30x40 but your light booth can only view 11x17? Well if you know that the print to display matching is good, you can at least print a smaller BAT image and if you're really good, do minor compensation for the document going to a larger size. This is all pretty controllable. Once you ask about where that 30x40 print will reside, and you take the display out of the equation, all bets are off. At least we can produce an environment where print and display are close such we get no surprises here.
