Lee Filters
Lee Filters is a manufacturer of colour filters and colour gels for the entertainment lighting, film and photography industries. Their colour gels for stage lighting are the industry standard in Europe while competing with other brands such as Rosco. The company was founded in 1967 as part of the group that became Lee International. Lee Filters is now owned by Panavision. In 1980, the company was awarded the Bert Easey Technical Award of the British Society of Cinematographers The British Society of Cinematographers (abbreviated B.S.C. or BSC) was formed in 1949 by Bert Easey (23 August 1901 – 28 February 1973), the then head of the Denham and Pinewood studio camera departments, to represent British cinematographers ... for "the development of motion picture filters and control mediums".

Colour
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of elec ...

Filter (optics)
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter. Filters mostly belong to one of two categories. The simplest, physically, is the absorptive filter; then there are interference or dichroic filters. Many optical filters are used for optical imaging and are manufactured to be transparent; some used for light sources can be translucent. Optical filters selectively transmit light in a particular range of wavelengths, that is, colours, while absorbing the remainder. They can usually pass long wavelengths only (longpass), short wavelengths only (shortpass), or a band of wavelengths, blocki ...

Lee International
Lee Electric (Lighting) Ltd was incorporated as a business in 1961 by John and Benny Lee, two film lighting electricians. Lee Electric was primarily involved in the rental of lighting equipment for commercial and documentary productions, as all principal film and television studios were at the time equipped with their own lighting equipment. From 1961 to 1985 Although the lighting rental market grew throughout the 1960s, largely due to the impact of commercial television, the market was dominated by a single manufacturer of lighting equipment, Mole-Richardson (England) Ltd, which was also the largest rental house. Lee Electric was founded as SunBurst Lighting by electrical engineer Bill Burst in 1961. In 1967 Lee Electric started to purchase lighting equipment from the Italian manufacturer, Ianiro, which was itself attempting to establish a foothold in the international market. In addition, Lee Filters was formed to design, market and, from 1974, to manufacture lighting fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panavision
Panavision is an American motion picture equipment company founded in 1953 specializing in cameras and lenses, based in Woodland Hills, California. Formed by Robert Gottschalk as a small partnership to create anamorphic projection lenses during the widescreen boom in the 1950s, Panavision expanded its product lines to meet the demands of modern filmmakers. The company introduced its first products in 1954. Originally a provider of CinemaScope accessories, the company's line of anamorphic widescreen lenses soon became the industry leader. In 1972, Panavision helped revolutionize filmmaking with the lightweight Panaflex 35 mm movie camera. The company has introduced other cameras such as the Millennium XL (1999) and the digital video Genesis (2004). Panavision operates exclusively as a rental facility—the company owns its entire inventory, unlike most of its competitors. Early history Robert Gottschalk founded Panavision in late 1953, in partnership with Richard M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Society Of Cinematographers
The British Society of Cinematographers (abbreviated B.S.C. or BSC) was formed in 1949 by Bert Easey (23 August 1901 – 28 February 1973), the then head of the Denham and Pinewood studio camera departments, to represent British cinematographers in the British film industry. The stated objectives at the formation of the BSC were: * To promote and encourage the pursuit of the highest standards in the craft of Motion Picture Photography. * To further the applications by others of the highest standards in the craft of Motion Picture Photography and to encourage original and outstanding work. * To co-operate with all whose aims and interests are wholly or in part related to those of the society. * To provide facilities for social intercourse between the members and arrange lectures, debates and meetings calculated to further the objects of the Society. There were originally 55 members. Currently, there are 256 full, honorary and associate members. For a British cinematographer, mem ...

Optical Filters
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that ...

Companies Based In Hampshire
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is generating profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations. Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups.

Photography Equipment
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Stage Lighting Instruments
Stage lighting instruments (lanterns, or 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. Many stagecraft terms vary between the United States and the United Kingdom. In the United States, lighting fixtures are often called "instruments" or "units". In the UK, they are called "lanterns" or "luminaires". This article mainly uses terms common to the United States. Components :''See the picture at the top of the page for the physical location of most components.'' Stage lighting instruments all have the following components: Housing The lamp housing is a metal or plastic container that serves as a body for the entire instrument and prevents light from spilling in unwanted directions. It comprises all of the exterior of the fixture except for the lens or opening. The housing may be designed with speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
