Cultural Heritage Imaging



Cultural Heritage Imaging (CHI) fosters the development and adoption of technologies for digital capture and documentation of the world’s cultural, scientific, and artistic treasures. We do this by collaborating with experts from around the world in cultural preservation, natural history collections, computer imaging science, museum/library science, and data archiving. 

Core set of technologies and brief definitions of each one of them are provided below. 

Reflectance Transformation Imaging (RTI) 
A breakthrough class of imaging techniques used in cultural heritage and natural history documentation and preservation, enabling the study of the minute details of surfaces

 Algorithmic Rendering (AR)
An applied mathematical method used to create scientifically reliable illustrations of cultural heritage and natural history subjects.

 Photogrammetry
The practice of determining mathematical measurements and three-dimensional (3D) geometry data from two or more photographic images of the same subject.

 Digital Lab Notebook
Digital lab notebook: a CHI term that describes the digital process history record of the means and circumstances used to generate a digital representation (digital surrogate) of an empirically captured subject in the physical world.

English Heritage

English Heritage (officially the Historic Building and Monuments Commission for England). is an executive non-departmental public body of the British Government sponsored by the Department for Culture, Media and Sport (DCMS). By caring for the built environment, English Heritage complements the work of Natural England which aims to protect the natural environment. It has a broad remit of managing the historic built environment of England and advises the relevant Secretary of State on policy and in individual cases such as registering listed buildings and scheduled ancient monuments. Simon Thurley has been chief executive since 2002.

It was set up under the terms of the National Heritage Act 1983. Its functions for maintaining ancient monuments had previously been undertaken by part of the Department of the Environment which was the successor to the Ministry of Works. The 1983 Act also dissolved the bodies that had hitherto provided independent advice — the Ancient Monuments Board for England and the Historic Buildings Council for England and incorporated these functions in the new body. Another advisory body, the Royal Commission on the Historical Monuments of England (RCHME) was not merged with English Heritage until 1 April 1999.

English Heritage's best known role is as the steward of over 400 significant historical and archaeological sites, from Stonehenge to the world's earliest iron bridge. It has direct ownership over some historic sites and also liaises with private owners of sites that are managed under guardianship arrangements. It has major responsibilities in conservation, giving advice, registering and protecting the historic environment. It also maintains a public archive, the English Heritage Archive, formerly known as the National Monuments Record (NMR).

Image


Images may be two-dimensional, such as a photograph, screen display, and as well as a three-dimensional, such as a statue or hologram. They may be captured by optical devices—such as cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water surfaces.
The word image is also used in the broader sense of any two-dimensional figure such as a map, a graph, a pie chart, or an abstract painting. In this wider sense, images can also be rendered manually, such as by drawing, painting, carving, rendered automatically by printing or computer graphics technology, or developed by a combination of methods, especially in a pseudo-photograph.

A volatile image is one that exists only for a short period of time. This may be a reflection of an object by a mirror, a projection of a camera obscura, or a scene displayed on a cathode ray tube. A fixed image, also called a hard copy, is one that has been recorded on a material object, such as paper or textile by photography or digital processes.

A mental image exists in an individual's mind: something one remembers or imagines. The subject of an image need not be real; it may be an abstract concept, such as a graph, function, or "imaginary" entity. For example, Sigmund Freud claimed to have dreamed purely in aural-images of dialogs. The development of synthetic acoustic technologies and the creation of sound art have led to a consideration of the possibilities of a sound-image made up of irreducible phonic substance beyond linguistic or musicological analysis.

A still image is a single static image, as distinguished from a kinetic image (see below). This phrase is used in photography, visual media and the computer industry to emphasize that one is not talking about movies, or in very precise or pedantic technical writing such as a standard.

A film still is a photograph taken on the set of a movie or television program during production, used for promotional purposes.
