Scanning Glass Plate Negative Film | Oxford UK
Archiving and Scanning Digitisation at Oxford Duplication Centre

Workflows for digitising glass plate negatives
Photographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass.
Our digitisation and scanning department can support public and corporate media to include glass plate negatives and lantern slides up to A3 in size. Once scanned the negatives can be converted into digital formats such as RAW, JPEG, JPEG2000, TIFF, BMP and Adobe PDF in full colour or greyscale.
All our machinery offer a high Dmax measurement of optical density which ensures the thinner parts of film (shadows in negatives or highlights in positives) reproduces detail in the deepest of shadows.
Working with museums, historical archival companies, corporations and private clients, we can cater for small units to bulk large orders in the many 1000's.
