The Preservation of Glass Plate Negatives | Digitising to National Archive Standard TIFF and JPEG Standards
We are one of leading archival specialists in the preservation of fragile heritage media. We can support you with glass plate negative scanning upto A3 in size.
Our archive specialist archive technicians are skilled in supporting our clients with the digitisation and scanning of fragile glass plate negative heritage materials. We are able to offer a scanning service for glass plate and lantern slides upto A3 in size.
HOW WE CAN SUPPORT YOU: Glass plates are first gently cleaned before being converted from negative images to positives. All slides are digitised to HQ TIFF images before we prepare Adobe Archival technique adjusting contrast and sharpness to ensure that you receive the clearest possible digital images.
OUTPUT IMAGES: Output images can be converted into digital formats to include RAW, JPEG, JPEG2000, TIFF, BMP and Adobe PDF in full colour or greyscale. Indexing, Metadata tagging, OCR and all forms of image processing can be offered as with all our digitisation services.
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.
WHAT TO KNOW ABOUT GLASS PLATE NEGATIVES
On one surface of the glass plate negative it has a light sensitive emulsion. The emulsion is very fragile and requires gentle handling. Our technicians are skilled in handling delicate valuable media and using preservation tools such as gloves and careful cleaning products we can prepare your glass plate negatives, before returning them back into their relevant envelopes or protective casings.
