PHOTOGRAPHIC GLASS PLATE NEGATIVE AND POSITIVE SCANNING SERVICES FOR CORPORATE AND CONSUMER CLIENTS IN OXFORDSHIRE UK

Oxford Duplication have established a preservation technique perfect for preserving photographic plates and prevent their valuable historical information from being lost. The emulsion on the plate can deteriorate. In addition, the glass plate medium is fragile and prone to cracking if not stored correctly.


History of Photography, Glass Plate and Tintype Ferrotype Negatives

There are 2 types of glass plate negatives and 1 type of tintype negative. Collodion Wet Plate and Gelatine Dry Plate and further below more information about Ferrotypes also known as Tintypes. 




Collodion Wet Plate Negatives - 1851 until the 1880s. Invented by Frederick Scoff Archer an English sculptor. Frederick used a viscous solution of collodion coated glass with light-sensitive silver salts. Glass plates created a sharper stable and detailed negative than paper. This was more supported by photographers who would produce several prints from one negative. These are identified by an unevenly coated emulsion with thick glass and rough edges.


Silver Gelatine Dry Plate Negatives - 1873 to around late 1920's. These were invented by Dr. Richard L. Maddox. Considered the first economically successful photographic medium because the gelatine dry plates were easier to transport and usable when dry. And because they needed less exposure to light, where thinner glass and more evenly coated emulsion these became a popular solution.




Glass Plate and Lantern Slide Negative Scanning Solutions

Photographic plates preceded photographic film as a capture medium in photography. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass, instead of a clear plastic film.

Glass plates were always deemed far superior to film especially for research-quality imaging because they were stable especially in large-format frames for wide-field imaging. Glass plate photographic material became less desirable in the consumer world as more convenient films were preferred. Although in the photographic fields these have still been used right upto the 1970's and in wide use by the professional astronomical fields upto 1990s.

The Preservation of The Curnock Glass Plate Negatives Introduction Our services ( @OxfordDuplicat1 )  are highly recommended in the UK for specialist photographic film scanning. Trusted to our company, we are preparing The Curnock glass plate collection, held at Oxford Brookes University and part of the  @MethodistGB collection. Almost all archives possess some type of photographic collection. Many individuals typically think of “photographs” as plastic-based negatives and slides; but these photographic techniques are relatively recent inventions. Prior to the invention of cellulose nitrate film in 1903, photographic emulsions were made on glass supports. These glass supports are typically referred to as glass plate negatives. The term “glass plate negative” refers to two separate formats: the collodion wet plate negative and the gelatin dry plate. Both of these formats consist of a light sensitive emulsion that is fixed to the glass plate base with a binder. Dozens of photographic te

Preserving Family Memories - caring for your heritage

Memories  are an important part of all our lives. Old letters, photographs, scrapbooks, slides and negatives, glass plates, cine film, audio-visual tapes and many other things help us to recall our past and the history of our family and communities.

Letters, Diaries, Books and Documents.   Many families preserve letters, diaries, or other written documents in which family members discuss their life and times. World War II remembrances have led many families to look for a relative's carefully stored letters. Other families have saved newspaper clippings of important family events, such as the announcements of births, m

How Magnetic's Can Destroy Your Family VHS Tape Memories

MAGNETIC DAMAGE TO FAMILY VIDEO TAPES Magnetic tape damage is pretty common. Family tapes store video and audio information in the form of a magnetic strip. The VCR has special heads that can pick up on these magnetic signals and translate them into images and sound that plays on your TV. While magnets are used to write information to the tape, they are also used to erase footage from your tape. Since VHS uses an iron oxide as its formula, this makes them very susceptible to magnetic damage. A tape that has been exposed to magnetic damage is nearly always irreparable. There is no way to recover footage that has been magnetically erased or damaged. The best bet is to make sure you keep your video tapes away from anything resembling a magnet! CLIENT CASE Unfortunately one of our clients contacted us Friday with regard to his family Hi8 video tapes that had been damaged by the magnetic field given off by a mobile phone. He asked whether our company would be able to help recover
