You Ask, We Answer: Why is it so Dark in Here?

A visitor recently wrote in our Japan Spring comment book wanting to know why it is “so dark” in the Hokusai exhibit. We asked Richard Skinner, F|S lighting designer extraordinaire, to field this one.

RS: Good question. Many of the objects on display at the Freer|Sackler are made with materials that can react to light, so it is necessary to carefully control what kind of light, how much light, and duration of exposure on these materials. The Hokusai prints are made with pigments that could easily fade or shift in color if overexposed to light. Curator Ann Yonemura has carefully selected the best copy available of each print—and to preserve these objects in their current pristine condition, the light level is restricted to 5 foot-candles of visible light. We carefully measure the light level at each individual object with an illuminance meter and also monitor how long lights are on each day using a digital data logging system. Typically, prints of this nature can only be displayed for a limited length of time before they must go back into storage.
