| Abstrakt: | SUMMARIES. The generally accepted approach for the visual documentation of all types of objects such as sculpture, paintings, books and works of art on paper, archival documents and others is to do so with photography. In photography (film and digital) extremely high resolutions can be achieved, yet regardless of the photographic format the final result is two dimensional. This has been the best non-contact approach until now. Today, non-contact three-dimensional (3D) imaging is available and has the capacity to electronically render an object’s shape, geometry and colour accurately. The potential of 3D imaging is a boon to conservation. It allows for the object’s preservation by providing both image/content and physical data unique to the object. The data provided are accurate and allow one to quantify any aspect of the condition of the objects not possible before. The data can be used: (1) as an analytical or diagnostic tool during object examination; (2) for monitoring physical/geometrical changes occurring to the object during conservation treatments; (3) for monitoring physical/ geometrical changes over longer periods (months, years, decades) when an object is on display, loan, storage or outdoors; and (4) in the preparation of replicas or facsimiles. Three-dimensional imaging is entering museums for use in preservation and providing access. Examples of 3D imaging from archaeological sites, museum objects and art on paper can be seen. |
