Revealing #palimpest with #multispectral #imaging! These amazing results, showing a #Merovingian overtext and a 5th-century Gospel undertext, were achieved by my colleague Alex Zawacki at Göttingen. I'll be presenting the full results of this and other cool discoveries in May at a German-language conference in Kiel.

My first image from my hacked-together #multispectral (IR, UV, and visible light) camera. Near IR is in red, visible light is in green, and UV is in blue.

The camera itself is a monochrome camera I normally use for solar imaging, while the lens is just a regular Nikon 50 f/1.8D. Between the two is an electronic filter wheel with IR pass, IR cut, and UV pass filters.
