              In this short video clip Abigail Quandt, Senior Conservator of Manuscripts and Rare Books at The Walters Art Museum, turns some pages of the book. It might surprise some people that Abigail is not wearing gloves. Actually it makes conservation sense. Her clean hands do no damage to the parchment and she can be more sensitive to the fragile folios if she is not wearing anything on them.

                If you look at things with different lights you see different things. It has long been known, for example, that we can retrieve under-drawings below paintings by looking at them in infrared light. This is because the carbon used by artists to make their under-drawing absorbs light at that range of the spectrum. These days, however, it is possible to post-process images to bring out more of what you want than is possible simply through image capture. And, of course, it is possible to use information from more than one image to do this.
