Well at least we raise the question; how our prints were intended to be viewed vs proper lighting technique vs as per the creator's instruction. It would be funny to see a florescent circle line kitchen light displaying an Ansel Adams museum photograph though.
There must be some standard somewhere for illuminating B&W archival prints? I notice a big difference in my prints when viewing in my back yard as opposed to my basement with 8' overhead florecent day light balanced bulbs (one warm, one cool). A curious problem, how will my prints look in a galery when I become famous after I'm dead for a 100 years?
Next time I visit the museum I am going to make a special note of checking the lighting with my meter and maybe asking someone in the know if they can give me more info.
