An art exhibition is traditionally the space in which art objects (in the most general sense) meet an audience. The exhibit is universally understood to be for some temporary period unless, as is occasionally true, it is stated to be a "permanent exhibition". In American English, they may be called "exhibit", "exposition" (the French word) or "show". In UK English, they are always called "exhibitions" or "shows", and an individual item in the show is an "exhibit".
Such expositions may present pictures, drawings, video, sound, installation, performance, interactive art, new media art or sculptures by individual artists, groups of artists or collections of a specific form of art.
The art works may be presented in museums, art halls, art clubs or private art galleries, or at some place the principal business of which is not the display or sale of art, such as a coffeehouse. An important distinction is noted between those exhibits where some or all of the works are for sale, normally in private art galleries, and those where they are not. Sometimes the event is organized on a specific occasion, like a birthday, anniversary or commemoration.
There are different kinds of art exhibitions, [1] in particular there is a distinction between commercial and non-commercial exhibitions. A commercial exhibition or trade fair is often referred to as an art fair that shows the work of artists or art dealers where participants generally have to pay a fee. A vanity gallery is an exhibition space of works in a gallery that charges the artist for use of the space. Temporary museum exhibitions typically display items from the museum's own collection on a particular period, theme or topic, supplemented by loans from other collections, mostly those of other museums. They normally include no items for sale; they are distinguished from the museum's permanent displays, and most large museums set aside a space for temporary exhibitions.
Exhibitions in commercial galleries are often entirely made up of items that are for sale, but may be supplemented by other items that are not. Typically, the visitor has to pay (extra on top of the basic museum entrance cost) to enter a museum exhibition, but not a commercial one in a gallery. Retrospectives look back over the work of a single artist; other common types are individual exhibitions or "solo shows", and group exhibitions or "group shows"). The Biennale is a large exhibition held every two years, often intending to gather together the best of international art; there are now many of these. A travelling exhibition is an exhibition seen at several venues, sometimes across the world.
Exhibitions of new or recent art can be juried, invitational, or open.
The art exhibition has played a crucial part in the market for new art since the 18th and 19th centuries. The Paris Salon, open to the public from 1737, rapidly became the key factor in determining the reputation, and so the price, of the French artists of the day. The Royal Academy in London, beginning in 1769, soon established a similar grip on the market, and in both countries artists put great efforts into making pictures that would be a success, often changing the direction of their style to meet popular or critical taste. The British Institution was added to the London scene in 1805, holding two annual exhibitions, one of new British art for sale, and one of loans from the collections of its aristocratic patrons. These exhibitions received lengthy and detailed reviews in the press, which were the main vehicle for the art criticism of the day. Critics as distinguished as Denis Diderot and John Ruskin held their readers attention by sharply divergent reviews of different works, praising some extravagantly and giving others the most savage put-downs they could think of. Many of the works were already sold, but success at these exhibitions was a crucial way for an artist to attract more commissions. Among important early one-off loan exhibitions of older paintings were the Art Treasures Exhibition, Manchester 1857, and the Exhibition of National Portraits in London, at what is now the Victoria and Albert Museum, held in three stages in 1866–1868.
As the academic art promoted by the Paris Salon, always more rigid than London, was felt to be stifling French art, alternative exhibitions, now generally known as the Salon des Refusés ("Salon of the Refused") were held, most famously in 1863, when the government allowed them an annex to the main exhibition for a show that included Édouard Manet's Luncheon on the Grass(Le déjeuner sur l'herbe) and James McNeill Whistler's Girl in White. This began a period where exhibitions, often one-off shows, were crucial in exposing the public to new developments in art, and eventually Modern art. Important shows of this type were the Armory Show in New York City in 1913 and the London International Surrealist Exhibition in 1936.
Museums started holding large loan exhibitions of historic art in the late 19th century, as also did the Royal Academy, but the modern "blockbuster" museum exhibition, with long queues and a large illustrated catalogue, is generally agreed to have been introduced by the exhibitions of artifacts from the tomb of Tutankhamun held in several cities in the 1970s. Many exhibitions, especially in the days before good photographs were available, are important in stimulating research in art history; the exhibition held in Bruges in 1902 (poster illustrated below) had a crucial impact on the study of Early Netherlandish painting.
In 1968, Art fairs in Europe became quite the fashion with the advent of the Cologne Art Fair [4] which was sponsored by the Cologne Art Dealers Association. Because of the high admission standards of the Cologne fair a rival fair was organized in Düsseldorf which enabled less regarded galleries opportunity to meet with an international public. The fairs took place during the fall months. This rivalry continued for a few years which provided the Basel Art Fair the opportunity to interject the Basel fair in early summer. These fairs became extremely important to galleries, dealers and publishers as they provided the possibility of worldwide distribution. Düsseldorf and Cologne merged their efforts. Basel soon became the most important art fair.
In 1976, the Felluss Gallery under the direction of Elias Felluss, in Washington DC organized the first American dealer art fair. "The Washington International Art Fair" or "Wash Art" for brevity. This American fair met with fierce opposition by those galleries interested in maintaining distribution channels for European artwork already in place. The Washington fair introduced the European idea of dealer fairs to art dealers throughout the United States. Following the advent of Wash Art, many fairs developed throughout the United States.
Although preservation issues are often disregarded in favor of other priorities during the exhibition process, they should certainly be considered so that possible damage to the collection is minimized or limited. As all objects in the library exhibition are unique and to some extent vulnerable, it is essential that they be displayed with care. Not all materials are able withstand the hardships of display, and therefore each piece needs to be assessed carefully to determine its ability to withstand the rigors of an exhibition. In particular, when exhibited items are archival artifacts or paper-based objects, preservation considerations need be emphasized because damage and change in such materials is cumulative and irreversible. [5] Two trusted sources – the National Information Standard Organization's [6] Environmental Conditions for Exhibiting Library and Archival Materials, and the British Library's Guidance for Exhibiting Library and Archive Materials – have established indispensable criteria to help curtail the deleterious effects of exhibitions on library and archival materials. These criteria may be divided into five main preservation categories: Environmental concerns of the exhibition space; Length of the exhibition; Individual cases; Display methods used on individual objects; and Security.
The main concerns of exhibition environments include light, relative humidity, and temperature.
Light wavelength, intensity, and duration contribute collectively to the rate of material degradation in exhibitions. [7] The intensity of visible light in the display space should be low enough to avoid object deterioration, but bright enough for viewing. A patron's tolerance of low-level illumination can be aided by reducing ambient light levels to a level lower than that falling on the exhibit. [7] Visible light levels should be maintained at between 50 lux and 100 lux depending on the light sensitivity of objects. [8] An items level of toleration will depend on the inks or pigments being exposed and the duration of the exhibition time. A maximum exhibition length should initially be determined for each exhibited item based on its light sensitivity, anticipated light level, and its cumulative past and projected exhibition exposure.
Light levels need to be measured when the exhibition is prepared. UV light meters will check radiation levels in an exhibit space, and data event loggers help determine visible light levels over an extended period of time. Blue wool standards cards can also be utilized to predict the extent to which materials will be damaged during exhibits. [9] UV radiation must be eliminated to the extent it is physically possible; it is recommended that light with a wavelength below 400 nm (ultraviolet radiation) be limited to no more than 75 microwatts per lumen at 10 to 100 lux. [8] Furthermore, exposure to natural light is undesirable because of its intensity and high UV content. When such exposure is unavoidable, preventative measures must be taken to control UV radiation, including the use of blinds, shades, curtains, UV filtering films, and UV-filtering panels in windows or cases. Artificial light sources are safer options for exhibition. Among these sources, incandescent lamps are most suitable because they emit little or no UV radiation. [10] Fluorescent lamps, common in most institutions, may be used only when they produce a low UV output and when covered with plastic sleeves before exhibition. [10] Though tungsten-halogen lamps are currently a favorite artificial lighting source, they still give off significant amounts of UV radiation; use these only with special UV filters and dimmers. [10] Lights should be lowered or turned off completely when visitors are not in the exhibition space.
The exhibition space's relative humidity (RH) should be set to a value between 35% and 50%. [8] The maximum acceptable variation should be 5% on either side of this range. Seasonal changes of 5% are also allowed. The control of relative humidity is especially critical for vellum and parchment materials, which are extremely sensitive to changes in relative humidity and may contract violently and unevenly if displayed in too dry an environment.
For preservation purposes, cooler temperatures are always recommended. The temperature of the display space should not exceed 72 °F. [11] A lower temperature of down to 50 °F can be considered safe for a majority of objects. The maximum acceptable variation in this range is 5 °F, meaning that the temperature should not go above 77 °F and below 45 °F. As temperature and relative humidity are interdependent, temperature should be reasonably constant so that relative humidity can be maintained as well. Controlling the environment with 24-hour air conditioning and dehumidification is the most effective way of protecting an exhibition from serious fluctuations.
One factor that influences how well materials will fare in an exhibition is the length of the show. The longer an item is exposed to harmful environmental conditions, the more likely that it will experience deterioration. Many museums and libraries have permanent exhibitions, and installed exhibitions have the potential to be on the view without any changes for years.
Damage from a long exhibition is usually caused by light. The degree of deterioration is different for each respective object. For paper-based items, the suggested maximum length of time that they should be on display is three months per year, or 42 kilolux hours of light per year – whichever comes first. [12]
An exhibition log report, including records of the length of the exhibition time and the light level of the display, may prevent objects from being exhibited too frequently. Displayed items need to be inspected regularly for evidence of damage or change. [12] It is recommended that high-quality facsimiles of especially delicate or fragile materials be displayed in lieu of originals for longer exhibitions. [13]
Library or archival materials are usually displayed in display cases or frames. Cases provide a physically and chemically secure environment. Vertical cases are acceptable for small or single-sheet items, and horizontal cases can be used for a variety of objects, including three-dimensional items such as opened or closed books, and flat paper items. All these objects can be arranged simultaneously in one horizontal case under a unified theme.
Materials used for case construction should be chosen carefully because component materials can easily become a significant source of pollutants or harmful fumes for displayed objects. Outgassing from materials used in the construction of the exhibition case and/or fabrics used for lining the case can be destructive. Pollutants may cause visible deterioration, including discoloration of surfaces and corrosion. Examples of evaluative criteria to be used in deeming materials suitable for use in exhibit display could be the potential of contact-transfer of harmful substances, water solubility or dry-transfer of dyes, the dry-texture of paints, pH, and abrasiveness. [14]
New cases may be preferred, constructed of safe materials such as metal, plexiglass, or some sealed woods. [13] Separating certain materials from the display section of an exhibition case by lining relevant surfaces with an impermeable barrier film will help protect items from damage. Any fabrics that line or decorate the case (for example, polyester blend fabric), and any adhesives used in the process, should also be tested to determine any risk. Using internal buffers and pollutant absorbers, such as silica gel, activated carbon, or zeolite, is a good way to control relative humidity and pollutants. Buffers and absorbers should be placed out of sight, in the base or behind the backboard of a case. If the case is to be painted, it is recommended oil paints be avoided; acrylic or latex paint is preferable.
There are two kinds of objects displayed at the library and archival exhibition – bound materials and unbound materials. Bound materials include books and pamphlets, and unbound materials include manuscripts, cards, drawings, and other two-dimensional items. The observance of proper display conditions will help minimize any potential physical damage. All items displayed must be adequately supported and secured.
Unbound materials, usually single-sheet items, need to be attached securely to the mounts, unless matted or encapsulated. Metal fasteners, pins, screws, and thumbtacks should not come in direct contact with any exhibit items. [15] Instead, photo corners, polyethylene, or polyester film straps may hold the object to the support. Objects may also be encapsulated in polyester film, though old and untreated acidic papers should be professionally deacidified before encapsulation. [5] Avoid potential slippage during encapsulation – when possible, use ultrasonic or heat seals. For objects that need to be hung (and that may require more protection than lightweight polyester film), matting would be an effective alternative.
Objects in frames should be separated from harmful materials through matting, glazing, and backing layers. Matting, which consists of two pH-neutral or alkaline boards with a window cut in the top board to enable the object to be seen, can be used to support and enhance the display of single sheet or folded items. Backing layers of archival cardboard should be thick enough to protect objects. Moreover, any protective glazing used should never come in direct contact with objects. [16] Frames should be well-sealed and hung securely, allowing a space for air circulation between the frame and the wall.
The most common way to display bound materials is closed and lying horizontally. If a volume is shown open, the object should be open only as much as its binding allows. Common practice is to open volumes at an angle no greater than 135°. [17] There are some types of equipment that help support volumes as they displayed openly: blocks or wedges, which hold a book cover to reduce stain at the book hinge; cradles, which support bound volumes as they lay open without stress to the binding structure; and polyester film strips, which help to secure open leaves. Textblock supports are best used in conjunction with book cradles where the textblock is greater than 1/2 inch, or where the textblock noticeably sags. [18] Regardless of its method of support, however, any book that is kept open for long periods can cause damage. One should turn an exhibited book's pages every few days in order to protect pages from overexposure to light and spread any strain on the binding structure.
Because exhibited items are often of special interest, they demand a high level of security to reduce the risk of loss from theft or vandalism. Exhibition cases should be securely locked. In addition, cases may be glazed with a material that hinders penetration and that when broken does not risk shards of glass falling on the exhibits. [19] Whenever possible, the exhibition area should be patrolled; a 24-hour security presence is recommended when precious treasures are exhibited. [20] Finally, the exhibition is best protected when equipped with intruder alarms, which can be fitted at entry points to the building and internal areas.
A museum is distinguished by a collection of often unique objects that forms the core of its activities for exhibitions, education, research, etc. This differentiates it from an archive or library, where the contents may be more paper-based, replaceable and less exhibition oriented, or a private collection of art formed by an individual, family or institution that may grant no public access. A museum normally has a collecting policy for new acquisitions, so only objects in certain categories and of a certain quality are accepted into the collection. The process by which an object is formally included in the collection is called accessioning and each object is given a unique accession number.
The conservation and restoration of textiles refers to the processes by which textiles are cared for and maintained to be preserved from future damage. The field falls under the category of art conservation, heritage conservation as well as library preservation, depending on the type of collection. The concept of textile preservation applies to a wide range of artifacts, including tapestries, carpets, quilts, clothing, flags and curtains, as well as objects which "contain" textiles, such as upholstered furniture, dolls, and accessories such as fans, parasols, gloves and hats or bonnets. Many of these artifacts require specialized care, often by a professional conservator.
In library classification systems, realia are three-dimensional objects from real life such as coins, tools, and textiles, that do not fit into the traditional categories of library material. They can be either man-made or naturally occurring, usually borrowed, purchased, or received as donation by a teacher, library, or museum for use in classroom instruction or in exhibits. Archival and manuscript collections often receive items of memorabilia such as badges, emblems, insignias, jewelry, leather goods, needlework, etc., in connection with gifts of personal papers. Most government or institutional archives reject gifts of non-documentary objects unless they have a documentary value. When accepting large bequests of mixed objects they normally have the donors sign legal documents giving permission to the archive to destroy, exchange, sell, or dispose in any way those objects which, according to the best judgement of the archivist, are not manuscripts or are not immediately useful for understanding the manuscripts. Recently, the usage of this term has been criticized by librarians based on the usage of term realia to refer to artistic and historical artifacts and objects, and suggesting the use of the phrase "real world object" to describe the broader categories of three-dimensional objects in libraries.
An exhibition, in the most general sense, is an organized presentation and display of a selection of items. In practice, exhibitions usually occur within a cultural or educational setting such as a museum, art gallery, park, library, exhibition hall, or World's fairs. Exhibitions can include many things such as art in both major museums and smaller galleries, interpretive exhibitions, natural history museums and history museums, and also varieties such as more commercially focused exhibitions and trade fairs.
The conservation and restoration of ivory objects is the process of maintaining and preserving objects that are ivory or include ivory material. Conservation and restoration are aimed at preserving the ivory material and physical form along with the objects condition and treatment documentation. Activities dedicated to the preservation of ivory objects include preventing agents of deterioration that specifically connect with ivory as a material, preventative conservation, and treatment of ivory objects. Conservators, curators, collections managers, and other museum personnel are in charge of taking the necessary measurements to ensure that ivory objects are well maintained and will make the decision for any conservation and restoration of the objects.
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.
Collection maintenance is an area of collections management that consists of the day-to-day hands on care of collections and cultural heritage. The primary goal of collections maintenance or preventive conservation is to prevent further decay of cultural heritage by ensuring proper storage and upkeep including performing regular housekeeping of the spaces and objects and monitoring and controlling storage and gallery environments. Collections maintenance is part of the risk management field of collections management. The professionals most involved with collections maintenance include collection managers, registrars, and archivists, depending on the size and scope of the institution. Collections maintenance takes place in two primary areas of the museum: storage areas and display areas.
Collections management involves the development, storage, and preservation of cultural property, as well as objects of contemporary culture in museums, libraries, archives and private collections. The primary goal of collections management is to meet the needs of the individual collector or collecting institution's mission statement, while also ensuring the long-term safety and sustainability of the cultural objects within the collector's care. Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage. The professionals most influenced by collections management include collection managers, registrars, and archivists.
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.
Conservation and restoration of objects made from plastics is work dedicated to the conservation of objects of historical and personal value made from plastics. When applied to cultural heritage, this activity is generally undertaken by a conservator-restorer.
The cultural property storage typically falls to the responsibility of cultural heritage institutions, or individuals. The proper storage of these objects can help to ensure a longer lifespan for the object with minimal damage or degradation. With so many different types of artifacts, materials, and combinations of materials, keepers of these artifacts often have considerable knowledge of the best practices in storing these objects to preserve their original state.
The exhibition of cultural property is a practice used by organizations where collected objects are put on display to the public. The objects are carefully chosen and placed together to offer educational value, and often to tell a story.
The conservation and restoration of fur objects is the preservation and protection of objects made from or containing fur. These pieces can include personal items like fur clothing or objects of cultural heritage that are housed in museums and collections. When dealing with the latter, a conservator-restorer often handles their care, whereas, for the public, professional furriers can be found in many neighborhoods.
Conservation-restoration of bone, horn, and antler objects involves the processes by which the deterioration of objects either containing or made from bone, horn, and antler is contained and prevented. Their use has been documented throughout history in many societal groups as these materials are durable, plentiful, versatile, and naturally occurring/replenishing.
The conservation and restoration of paintings is carried out by professional painting conservators. Paintings cover a wide range of various mediums, materials, and their supports. Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices. All components of a painting will react to its environment differently, and impact the artwork as a whole. These material components along with collections care will determine the longevity of a painting. The first steps to conservation and restoration is preventive conservation followed by active restoration with the artist's intent in mind.
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-restoration of panel paintings involves preventive and treatment measures taken by paintings conservators to slow deterioration, preserve, and repair damage. Panel paintings consist of a wood support, a ground, and an image layer. They are typically constructed of two or more panels joined together by crossbeam braces which can separate due to age and material instability caused by fluctuations in relative humidity and temperature. These factors compromise structural integrity and can lead to warping and paint flaking. Because wood is particularly susceptible to pest damage, an IPM plan and regulation of the conditions in storage and display are essential. Past treatments that have fallen out of favor because they can cause permanent damage include transfer of the painting onto a new support, planing, and heavy cradling. Today's conservators often have to remediate damage from previous restoration efforts. Modern conservation-restoration techniques favor minimal intervention that accommodates wood's natural tendency to react to environmental changes. Treatments may include applying flexible battens to minimize deformation or simply leaving distortions alone, instead focusing on preventive care to preserve the artwork in its original state.
The conservation and restoration of wooden artifacts refers to the preservation of art and artifacts made of wood. Conservation and restoration in regards to cultural heritage is completed by a conservator-restorer.
The Conservation of South Asian household shrines is an activity dedicated to the preservation of household shrines from South Asia. When applied to cultural heritage, held by either museums or private collectors, this activity is generally undertaken by a conservator-restorer. South Asian shrines held in museum collections around the world are principally shrines relate to Hindu, Jain, or Buddhist households. Due to their original use and sacred nature, these shrines present unique conservation and restoration challenges for those tasked with their care.
The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects. Also referred to as the 'agents of change', the framework was first developed in the late 1980s and early 1990s. The defined agents reflect and systematise the main chemical and physical deterioration pathways to which most physical material is subject. They are a major influence on the applied practice of conservation, restoration, and collection management, finding particular use in risk management for cultural heritage collections.
