Soft Box
A soft box is a type of photographic lighting device, one of a number of photographic soft light devices. All the various soft light types create even and diffused lightBrooks, David. ''How to Control and Use Photographic Lighting''. HPBooks, 1980, p. 54. by transmitting light through some scattering material, or by reflecting light off a second surface to diffuse the light. The best known form of reflective source is the umbrella light, where the light from the bulb is "bounced" off the inside of a metalized umbrella to create an indirect "soft" light. A soft box is an enclosure around a bulb comprising reflective side and back walls and a diffusing material at the front of the light. The sides and back of the box are lined with a bright surface - an aluminized fabric surface or an aluminum foil, to act as an efficient reflector. In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella reflecto ...

Floodlight
A floodlight is a broad-beamed, high-intensity artificial light. They are often used to illuminate outdoor playing fields while an outdoor sports event is being held during low-light conditions. More focused kinds are often used as a stage lighting instrument in live performances such as concerts and plays. In the top tiers of many professional sports, it is a requirement for stadiums to have floodlights to allow games to be scheduled outside daylight hours. Evening or night matches may suit spectators who have work or other commitments earlier in the day, and enable television broadcasts during lucrative primetime hours. Some sports grounds which do not have permanent floodlights installed may make use of portable temporary ones instead. Many larger floodlights (see bottom picture) will have gantries for bulb changing and maintenance. These will usually be able to accommodate one or two maintenance workers. Types The most common type of floodlight is the metal-halid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speed Ring
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude (mathematics), magnitude of the change of its Position (vector), position over time or the magnitude of the change of its position per unit of time; it is thus a Scalar (physics), scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the Time in physics, duration of the interval; the instantaneous speed is the limit (mathematics), limit of the average speed as the duration of the time interval approaches zero. Speed is #Difference between speed and velocity, not the same as velocity. Speed has the dimensional analysis, dimensions of distance divided by time. The International System of Units, SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the Kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beauty Dish
A beauty dish is a photographic lighting device that uses a parabolic reflector to distribute light towards a focal point. The light created is between that of a direct flash and a softbox A soft box is a type of photographic lighting device, one of a number of photographic soft light devices. All the various soft light types create even and diffused lightBrooks, David. ''How to Control and Use Photographic Lighting''. HPBooks, ..., giving the image a wrapped, contrasted look, which adds a more dramatic effect. Uses There are many uses for a beauty dish, but its basic function is to provide a focused source of light for photographers. The beauty dish is used in portrait and fashion photography, because it is the best modifier for concentrating light on a subject and creating a better image than other modifiers. Because the beauty dish wraps the light around the subject it gives the image a better contrast and highlights angles that other modifiers wouldn't be able to high ...

Reflector (photography)
In photography and cinematography, a reflector is an improvised or specialised reflective surface used to redirect light towards a given subject or scene. Types Apart from certain highly specialized components found in enlargers, projectors and scanners, photographic reflectors fall into two main groups: Lamp reflectors Similar to a domestic lampshade, these reflectors are fixed to an artificial light source (for example, a filament bulb or flash tube) to direct and shape the otherwise scattered light, reflecting it off their concave inner surfaces and directing it towards the scene to be photographed. Although there are a large number of variants, the most common types are: * spherical, short-sided, giving a relatively broad spread of light; * parabolic, providing a tighter, parallel beam of light. The ''reflector factor'' is the ratio of the illumination provided by a lamp fitted within a reflector to the illumination provided without any reflector fitted. A matte refl ...

Striplight
A striplight is a multi-circuit stage lighting instrument. Striplights are one of the most basic types of lighting fixtures available. They usually consist of row of lamps. A single striplight is usually wired internally into either 3 or 4 circuits. Each internal circuit consists of several lamps evenly spaced within the unit. Often, a lighting designer will use roundels (colored glass lenses) or gels to make these lights different colors. The unit can then be wired into several different circuits, allowing each bank of colored lights to be controlled by a separate dimmer on the lighting board. Striplights are often used to color a cyclorama, or can alternately be positioned behind the proscenium arch to provide a general overhead color wash. Often, in older and low budget venues such as churches and schools, striplights are the primary lighting source. Nowadays, LED striplights are becoming more common. These units can deliver a similar light output with reduced power consu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescent
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacuu ...

Flash (photography)
A flash is a device used in photography that produces a brief burst of light (typically lasting 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a ''hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...
