Film preservation, or film restoration, describes a series of ongoing efforts among film historians, archivists, museums, cinematheques, and non-profit organizations to rescue decaying film stock and preserve the images they contain. In the widest sense, preservation assures that a movie will continue to exist in as close to its original form as possible.
Digitization is the process of converting information into a digital format. The result is the representation of an object, image, sound, document, or signal obtained by generating a series of numbers that describe a discrete set of points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerical format"; the decimal or any other number system can be used instead.
Conservation and restoration of immovable cultural property describes the process through which the material, historical, and design integrity of any immovable cultural property are prolonged through carefully planned interventions. The individual engaged in this pursuit is known as an architectural conservator-restorer. Decisions of when and how to engage in an intervention are critical to the ultimate conservation-restoration of cultural heritage. Ultimately, the decision is value based: a combination of artistic, contextual, and informational values is normally considered. In some cases, a decision to not intervene may be the most appropriate choice.
A microform is a scaled-down reproduction of a document, typically either photographic film or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
In Germany, photo rights or "Bildrechte" are the copyrights that are attached to the "author" of the photograph and are specified in the "Law for Copyright and similar Protection". These rights deal with rights of reproduction, distribution, modification, attribution, and prohibitions against illegal modification or reproduction. The ownership rights of a picture are treated under the broader "art copyright laws". Furthermore, if a museum or gallery owns a work of art or a photograph, they are permitted to make their own stipulations as to the selling of illustrations and reproductions of their property. This relates to the German legal concept of the right of owner to undisturbed possession. Wolf Vostell said: "Copyrights are like human rights".
Audio restoration is the process of removing imperfections from sound recordings. Audio restoration can be performed directly on the recording medium, or on a digital representation of the recording using a computer. Record restoration is a particular form of audio restoration that seeks to repair the sound of damaged gramophone records.
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.
In conservation, library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a conservator, librarian, archivist, or other professional when they perceive a collection or record is in need of maintenance.
The Brittle Books Program is an initiative carried out by the National Endowment for the Humanities at the request of the United States Congress. The initiative began officially between 1988 and 1989 with the intention to involve the eventual microfilming of over 3 million endangered volumes.
Inpainting is a conservation process where damaged, deteriorated, or missing parts of an artwork are filled in to present a complete image. This process is commonly used in image restoration. It can be applied to both physical and digital art mediums such as oil or acrylic paintings, chemical photographic prints, sculptures, or digital images and video.
Paper prints of films were an early mechanism to establish the copyright of motion pictures by depositing them with the Library of Congress. Thomas Alva Edison’s company was first to register each frame of motion-picture film onto a positive paper print, in 1893. The Library of Congress processed and cataloged each of the films as one photograph, accepting thousands of paper prints of films over a twenty-year period.
Bridgeman Art Library v. Corel Corp., 36 F. Supp. 2d 191, was a decision by the United States District Court for the Southern District of New York, which ruled that exact photographic copies of public domain images could not be protected by copyright in the United States because the copies lack originality. Even though accurate reproductions might require a great deal of skill, experience, and effort, the key element to determine whether a work is copyrightable under US law is originality.
In July 2009, lawyers representing the National Portrait Gallery of London (NPG) sent an email letter warning of possible legal action for alleged copyright infringement to Derrick Coetzee, an editor/administrator of the free content multimedia repository Wikimedia Commons, hosted by the Wikimedia Foundation.
Art historical photo archives are collections of reproductions of works of art that document paintings, drawings, prints, sculpture, architecture and sometimes installation photos. They are essential resource tools for the study of art history. Image collections deepen understanding of specific objects of art and the careers of individual artists as they also provide the means for a comparative approach to the study of artists’ works, national schools and period styles. The documentation that accompanies the images can also reveal patterns of art collecting, art market fluctuations and the changeable nature of public opinion. Photo archives build their collections and gather documentation for the works of art they record through purchases, gifts and photography campaigns. Information about ownership, condition, attribution, and subject identification is recorded at the time of acquisition and is frequently updated.
Conservation and restoration of movable cultural property is a term used to denote the conservation of movable cultural property items in libraries, archives, museums and private collections. Conservation encompasses all the actions taken toward the long-term preservation of cultural heritage. Activities include examination, documentation, treatment, and preventive care, which is supported by research and education. Object conservation is specifically the actions taken to preserve and restore cultural objects. The objects span a wide range of materials from a variety of cultures, time periods, and functions. Object conservation can be applied to both art objects and artifacts. Conservation practice aims to prevent damage from occurring, a process known as 'preventive conservation'. The purpose of preventive conservation is to maintain, and where possible enhance, the condition of an object, as well as managing deterioration risks, such as handling and environmental conditions. Historically, object conservation was focused on the category of fine arts but now many different types of objects are conserved. Each type of object material, typically denoted by organic or inorganic then the specific medium, requires a specialized professional conservator and often requires collaborative work between museum staff, scientists, and conservators.
The conservation and restoration of books, manuscripts, documents, and ephemera is an activity dedicated to extending the life of items of historical and personal value made primarily from paper, parchment, and leather. When applied to cultural heritage, conservation activities are generally undertaken by a conservator. The primary goal of conservation is to extend the lifespan of the object as well as maintaining its integrity by keeping all additions reversible. Conservation of books and paper involves techniques of bookbinding, restoration, paper chemistry, and other material technologies including preservation and archival techniques.
The conservation and restoration of time-based media art is the practice of preserving time-based works of art. Preserving time-based media is a complex undertaking within the field of conservation that requires an understanding of both physical and digital conservation methods. It is the job of the conservator to evaluate possible changes made to the artwork over time. These changes could include short, medium, and long-term effects caused by the environment, exhibition-design, technicians, preferences, or technological development. The approach to each work is determined through various conservation and preservation strategies, continuous education and training, and resources available from institutions and organization across the globe.
A photograph conservator is a professional who examines, documents, researches, and treats photographs, including documenting the structure and condition of art works through written and photographic records, monitoring conditions of works in storage and exhibition and transit environments. This person also performs all aspects of the treatment of photographs and related artworks with adherence to the professional Code of Ethics.
The conservation and restoration of film is the physical care and treatment of film-based materials. These include photographic film and motion picture film stock.
The conservation and restoration of photographic plates is the practice of caring for and maintaining photographic plates to preserve their materials and content. It covers the necessary measures that can be taken by conservators, curators, collection managers, and other professionals to conserve the material unique to photographic plate processes. This practice includes understanding the composition and agents of deterioration of photographic plates, as well as the preventive conservation and interventive conservation measures that can be taken to increase their longevity.
