identical with the already mentioned photons.
Because the color of the spectrum emitted by a blackbody radiator changes
with temperature, it is useful to introduce the term color temperature. With this

Digital Radiographic Image Acquisition and Processing

the size and layers of crystals in the film and screen.
In CR, speed is not exactly the same because there

Conservation and restoration of photographs
The Conservation and restoration of photographs is the study of the physical care and treatment of photographic materials. It covers both efforts undertaken by photograph conservators, librarians, archivists, and museum curators who manage photograph collections at a variety of cultural heritage institutions, as well as steps taken to preserve collections of personal and family photographs. It is an umbrella term that includes both preventative preservation activities such as environmental control and conservation techniques that involve treating individual items. Both preservation and conservation require an in-depth understanding of how photographs are made, and the causes and prevention of deterioration. Conservator-restorers use this knowledge to treat photographic materials, stabilizing them from further deterioration, and sometimes restoring them for aesthetic purposes.While conservation can improve the appearance of a photograph, image quality is not the primary purpose of conservation. Conservators will try to improve the visual appearance of a photograph as much as possible, while also ensuring its long-term survival and adhering the profession's ethical standards. Photograph conservators also play a role in the field of connoisseurship. Their understanding of the physical object and its structure makes them uniquely suited to a technical examination of the photograph, which can reveal clues about how, when, and where it was made.Photograph preservation is distinguished from digital or optical restoration, which is concerned with creating and editing a digital copy of the original image rather than treating the original photographic material. Photograph preservation does not normally include moving image materials, which by their nature require a very different approach. Film preservation concerns itself with these materials.
