Q:Information: - Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. - Stage lighting is the craft of lighting as it applies to the production of theatre, dance, opera and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians. - Geneva (, , , ) is the second most populous city in Switzerland (after Zurich) and is the most populous city of Romandy, the French-speaking part of Switzerland. Situated where the Rhone exits Lake Geneva, it is the capital of the Republic and Canton of Geneva. - Louis Paul Amedee Appia (13 October 1818 - 1 May 1898) was a Swiss surgeon with special merit in the area of military medicine. In 1863 he became a member of the Geneva "Committee of Five", which was the precursor to the International Committee of the Red Cross. Six years later he met Clara Barton, an encounter which had significant influence on Clara Barton's subsequent endeavours to found a Red Cross society in the United States and her campaign for an accession of the US to the Geneva Convention of 1864. - Theatre or theater is a collaborative form of fine art that uses live performers, typically actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek (theatron, "a place for viewing"), itself from (theaomai, "to see", "to watch", "to observe"). - A fog machine, fog generator, or smoke machine is a device that emits a dense vapor that appears similar to fog or smoke. This artificial fog is most commonly used in professional entertainment applications, but smaller, more affordable fog machines are becoming common for personal use. Fog machines can also be found in use in a variety of industrial, training, and some military applications. Typically, fog is created by vaporizing proprietary water and glycol-based or glycerin-based fluids or through the atomization of mineral oil. This fluid (often referred to colloquially as "fog juice") vaporizes or atomizes inside the fog machine. Upon exiting the fog machine and mixing with cooler outside air the vapor condenses, resulting in a thick visible fog. - Opera (English plural: "operas"; Italian plural: "opere" ) is an art form in which singers and musicians perform a dramatic work combining text (libretto) and musical score, usually in a theatrical setting. In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. - A performance, in the performing arts, generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand. Afterwards audience members often applaud. - The International Committee of the Red Cross (ICRC) is a humanitarian institution based in Geneva, Switzerland and a three-time Nobel Prize Laureate. State parties (signatories) to the four Geneva Conventions of 1949 and their Additional Protocols of 1977 (Protocol I, Protocol II) and 2005 have given the ICRC a mandate to protect victims of international and internal armed conflicts. Such victims include war wounded, prisoners, refugees, civilians, and other non-combatants. - Clarissa "Clara" Harlowe Barton (December 25, 1821 April 12, 1912) was a pioneering nurse who founded the American Red Cross. She was a hospital nurse in the American Civil War, a teacher, and patent clerk. Barton is noteworthy for doing humanitarian work at a time when relatively few women worked outside the home. She had a relationship with John J. Elwell and received three proposals throughout her lifetime, but never married. - Adolphe Appia ( 1 September 1862 -- 29 February 1928 ) , son of Red Cross co-founder Louis Appia , was a Swiss architect and theorist of stage lighting and decor . Appia is best known for his many scenic designs for Wagner 's operas . He rejected painted two - dimensional sets for three - dimensional '' living '' sets because he believed that shade was as necessary as light to form a connection between the actor and the setting of the performance in time and space . Through the use of control of light intensity , colour and manipulation , Appia created a new perspective of scene design and stage lighting . Directors and designers have both taken great inspiration from the work of Adolphe Appia , whose design theories and conceptualizations of Wagner 's operas have helped to shape modern perceptions of the relationship between the performance space and lighting . One of the reasons for the influence of Appia 's work and theories , is that he was working at time when electrical lighting was just evolving . Another is that he was a man of great vision who was able to conceptualize and philosophize about many of his practices and theories . The central principle underpinning much of Appia 's work is that artistic unity is the primary function of the director and the designer . Appia maintained that two dimensional set painting and the performance dynamics it created , was the major cause of production disunity in his time . He advocated three elements as fundamental to creating a unified and effective mise en scene : Dynamic and three dimensional movements by actors Perpendicular scenery Using depth and the horizontal dynamics of the performance space ( Brockett 1994 ) Appia saw light , space and the human body as malleable commodities which should be integrated to create a unified mise en scene . He advocated synchronicity of sound , light and movement in his productions of Wagner 's operas and he tried to integrate corps of actors with the rhythms and moods of the music . Ultimately however , Appia considered... - Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin. - Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400700 nanometres (nm), or 4.00 10 to 7.00 10m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430750 terahertz (THz). - Stage lighting instruments (or lanterns / Luminaires in Europe) are used in stage lighting to illuminate theatrical productions, concerts, and other performances taking place in live performance venues. They are also used to light television studios and sound stages. What is the relationship between 'adolphe appia' and 'geneva'?
