Interactive, User-Directed Lighting? KWAB in the Rijksmuseum, Amsterdam

This last post about the KWAB exhibition in Amsterdam's Rijksmuseum concerns lighting. This show got me and my partner-in-museology thinking about the potential for self-directed lighting in museum display. The impetus was this lovely, huge, embossed silver platter. Its fabulously fine relief is hard to see in any detail, not because the lighting is poor per se, but because it is static. Especially for objects that would have been handled, passed around, held up to the light, or simply displayed in a space where people could view it from different angles, the viewing conditions offered by a museum could hardly be more different. And it can be frustrating to try to make out what all those tiny relief people are doing on this silver thing; even I was inclined to give up and move on to something more decipherable. But adding a couple of pink hands as a reflecting screen (above right) changed everything—even more so when moved from side to side! The addition of not only light but color and movement made the relief eminently more legible. This is the reason that Reflectance Transformation Imaging works so well (here's the process): under different lighting conditions, especially ones we can adjust and move at will, we can perceive relief and texture much more easily.

So how about visitor-directed lighting? This could be as simple as offering visitors sheets of printer paper at the entrance and encouraging them to use it as a reflecting screen (on objects in glass cases only, if you're worried about paper and people getting near unprotected objects). But personally I think it would be exciting as a central element of a show; it could even be the main topic, "Old Things in New Light." You could experiment with little lights mounted on tracks in front of the objects, so the visitor can slide the light from side to side. Heck, grab that gooseneck lamp from your desk and mount it next to an object—there, you've got interactive, user-directed lighting! There are dozens of forms this could take, and just as many epiphanies about the objects in new light. Let's go wild and see what happens.
