Photoflood lamps are a type of incandescent light bulb designed for use as a continuous light source for photographic lighting. [1] The filaments of such lamps are operated at much higher temperatures than is the case for standard, general lighting service lamps. The result is a brilliance of light much higher than the lamp's wattage rating ...
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 softbox is an enclosure around a bulb comprising reflective side and back walls and a diffusing material at the front of the light.
It is used by photography professionals viewing transparent films, such as slides. [2] This device was originally used to sort photographic plates with ease. When laid flat, it may be called a light table. Generally, a lightbox uses light similar to daylight (5,000–6,000 kelvins (K)) and has uniform light strength on the glass pane. [3]
Video demonstration of high-speed flash photography. A flash is a device used in photography that produces a brief burst of light (lasting around 1 ⁄ 200 of a second) at a color temperature of about 5500 K [1] [citation needed] to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene.
The best designs use a supercapacitor instead of a rechargeable battery, since these have a longer working life than a battery. This, along with the long-life light-emitting diode which does not burn out like an incandescent bulb, give the flashlight a long lifetime, making it a useful emergency light. A disadvantage of many current models is ...
Internally triggered Strobotrons (light-output optimized thyratrons) were available [9] as well as flood-beam-CRT-type, grid-controlled Vacuum stroboscopic light sources with fast phosphors. [10] The strobe light was popularized on the club scene during the 1960s when it was used to reproduce and enhance the effects of LSD trips.
