Specialist digitisation of nitrate, acetate safety film, polyester film, negatives and photographic transparencies, with preservation workflows aligned to published National Archives digitisation guidance.
Photographic film can contain unique evidence of people, places, buildings, businesses, events and family history. As the physical film ages, the objective of digitisation is not simply to produce a convenient copy, but to create a faithful, well-controlled digital representation that can support preservation, cataloguing, research, publication and public access.
Oxford Duplication Centre provides specialist digitisation for nitrate film, acetate safety film and polyester film, together with photographic negatives, transparencies and related heritage collections. Projects are assessed according to the film base, emulsion, format, condition, dimensions and intended use so that the capture specification is appropriate to the original material.
Historic cellulose nitrate film requires careful assessment because deterioration can progress from fading and discoloration to sticky, bubbling or powdering material. We assess condition before determining whether the material is suitable for studio digitisation.
Cellulose acetate film can develop vinegar syndrome, shrinkage, brittleness, warping and other deterioration. We use condition-led handling and capture procedures appropriate to fragile safety film collections.
Polyester film bases are generally more dimensionally stable, but the photographic emulsion remains vulnerable to scratching, abrasion, dirt and poor storage. High-quality digitisation protects access to the image while reducing unnecessary handling of the original.
The National Archives publishes technical guidance covering image resolution, colour, file formats, quality assurance, metadata and fixity. We use these principles when designing preservation-focused photographic film projects, while agreeing the final specification with the client and collection requirements.
The technical principles above are based on The National Archives' current published digitisation guidance. Project specifications may vary according to the original material, collection condition and intended purpose.
A controlled workflow helps ensure that the digital files remain traceable to the physical collection and that problems are identified before a batch is accepted.
Preservation and access have different purposes. We can create a high-quality master for long-term retention and separate derivative files for everyday viewing, sharing, publication or online access.
High-resolution TIFF or another agreed preservation format, with the capture specification and technical metadata documented for the project.
Convenient, smaller files for browsing, research, sharing, websites and routine access without repeatedly handling the original film.
Where required, PDF or other derivatives can be produced from the high-quality master for reports, catalogues, research packs and publication workflows.
A preservation project should retain more than the image alone. We can work with your preferred collection identifiers and file-naming structure so that digital files remain associated with the original collection and can be managed after delivery.
Not every film should be handled in the same way. Nitrate and acetate collections in particular can deteriorate significantly, while damaged, warped, shrunken or brittle film may require an assessment before capture.
Our technicians can identify visible deterioration and discuss the practical options with the collection owner. Where a film appears to present a serious deterioration or safety concern, specialist conservation or hazardous-material advice should be obtained before attempting digitisation.
The aim is to maximise the information captured while minimising unnecessary handling of the original material.
If you have a photographic film collection held by an archive, museum, library, university, historic house, business or family, we can help develop a preservation-focused digitisation specification around the material.
