I was intrigued with Mark's discussion regarding museum lighting and how the best paintings without the proper lighting might otherwise appear dark. Then it occurred to me that if we paint in a studio with not enough lighting, we might tend to make our paintings a bit lighter than ideal, whereupon in quality museum lighting, they would appear to be 'washed out". I think.
Anyway, about half a dozen 1600 lumen bulbs at about 8 feet at 35 degrees might be the 'right' lighting. I was wondering if we could use a camera meter taken off a toned canvas to determine a proper lighting brightness?
