Many of the books in the Nature Bound: Illustrated Botanical Books exhibition feature very delicate, hand-colored illustrations that require an extra level of care. The pigments in the watercolor media used to color the images are very sensitive to light. Exposure to intense light or even lower light levels over a long duration can cause the colors to fade. Though we keep the light levels quite low in the gallery, the duration of the exhibition was long enough to require that we choose new illustrations about halfway through. Early last week we rotated the images on about twenty books. We found that this was not an easy task because it required that the new images continue to work with thematic and aesthetic relationships in the exhibition. In a few cases, it also meant that our art handlers had to create new plastic cradles in order to hold the book open to the new page. But the bonus for our viewers is that they now have the good fortune to see a fresh selection of images. Many of them are at least as, if not more, stunning than the last round. Please come by and take a look!
