Antique Pictureology


Rubylith has long been used in the printing industry as a masking film to restrict the transmission of UV light. Wet plate photographers utilize Rubylith to cover glass windows in portable darkboxes, thus allowing visible spectrum light to naturally illuminate the interior of the darkbox.  We offer Rubylith in two thicknesses, .005 inch (.15mm) and .003 inch (.10mm), and recommend the .005. Please contact us for pricing on .003 inch and sizes other than 8 x 10 inch.
