This point raises a question--what's a reasonable light level for print viewing? I just remembered I had an illumination meter, so I checked the level at my computer-area-now-converted-to-5000K-lamps. I'm reading about 600 lux down at the keyboard level where I usually hold prints for viewing. It isn't quite as bright as my darkroom (which runs about 850 lux at countertop level), but it seems pretty bright. Are there standards for this for graphic arts or some related area?
