==Methods of Imaging Watermarks==
===Photogram===
Thomas L. Gravell developed a system for imaging watermarks using Du Pont DYLUX® 503 photosensitive paper. 
The Archive of Watermarks and Papers in Greek Manuscripts describes the procedure here. 
 
=== Beta Radiography ===
CAMEO describes this technique in their page on Beta radiography.
In 2018, the paper lab at the Art Institute of Chicago developed a protocol for beta radiography that replaces the Kodak film with phosphor-coated imaging plates. This offers several advantages including: a larger surface area, higher sensitivity to beta rays, lower sensitivity to visible light, and they are reusable. Practically, these features translate into significantly shorter collection times (between 10-40 minutes, depending on the thickness of the support), a setup that is safer for the art (i.e. does not have to be carried out in total blackness), and a digital image that is easily manipulated with basic Image Pilot Konica software. The method is detailed in their "Beta Radiography Protocols" ().

=== Multispectral Imaging ===
===Digital Manipulation of Watermark Images===
Images of watermarks can be dramatically improved by digital manipulation. The following are examples of a technique developed by Claire Valero for enhancing transmitted light images. Ms. Valero presented the technique at the BPG Tips Session at AIC Annual in Houston. The handout and training videos are available on the BPG Annual Meeting Tips Sessions page . The technique is also described in Conservation Highlights on the Library of Congress Preservation Directorate website.
