The spring struck a primer tube at the base of the bulb, which contained a fulminate , which in turn ignited shredded zirconium foil in the flash. A Magicube could also be fired using a key or paper clip to trip the spring manually. X-cube was an alternate name for Magicubes, indicating the appearance of the camera's socket.
Other common flashbulb-based devices were the Flashbar and Flipflash, which provided ten flashes from a single unit. The bulbs in a Flipflash were set in a vertical array, putting a distance between the bulb and the lens, eliminating red eye. The Flipflash name derived from the fact that once half the flashbulbs had been used, the unit had to be flipped over and re-inserted to use the remaining bulbs.
In many Flipflash cameras, the bulbs were ignited by electrical currents produced when a piezoelectric crystal was struck mechanically by a spring-loaded striker, which was cocked each time the film was advanced. Electronic flash[ edit ] The electronic flash tube was introduced by Harold Eugene Edgerton in ;  he made several iconic photographs, such as one of a bullet bursting through an apple.
The large photographic company Kodak was initially reluctant to take up the idea. Early units were expensive, and often large and heavy; the power unit was separate from the flash head and was powered by a large lead-acid battery carried with a shoulder strap.
Towards the end of the s electronic flashguns of similar size to conventional bulb guns became available; the price, although it had dropped, was still high. The electronic flash system eventually superseded bulb guns as prices came down. A typical electronic flash unit has electronic circuitry to charge a high-capacitance capacitor to several hundred volts.
Synchronization was problematic with bulbs, which if ignited simultaneously with shutter operation would not reach full brightness before the shutter closed. A single electronic flash unit is often mounted on a camera's accessory shoe or a bracket; many inexpensive cameras have an electronic flash unit built in. For more sophisticated and longer-range lighting several synchronised flash units at different positions may be used.
Two professional xenon tube flashes Ring flashes that fit to a camera's lens can be used for shadow free macro photography, There are a few lenses with built-in ring-flash. They usually contain a modeling light , an incandescent light bulb close to the flash tube; the continuous illumination of the modeling light lets the photographer visualize the effect of the flash. A system may comprise multiple synchronised flashes for multi-source lighting.
The strength of a flash device is often indicated in terms of a guide number designed to simplify exposure setting. The energy released by larger studio flash units, such as monolights , is indicated in watt-seconds.
Canon and Nikon name their electronic flash units Speedlite and Speedlight respectively, and these terms are frequently used as generic terms for electronic flash equipment. High speed flash[ edit ] An air-gap flash is a high-voltage device that discharges a flash of light with an exceptionally short duration, often much less than one microsecond.
These are commonly used by scientists or engineers for examining extremely fast-moving objects or reactions, famous for producing images of bullets tearing through light bulbs and balloons see Harold Eugene Edgerton. An example of a process by which to create a high speed flash is the exploding wire method. The photo was taken in a darkened room, with camera's shutter open and the flash was triggered by the sound of the shot using a microphone.
Multi-flash[ edit ] A camera that implements multiple flashes can be used to find depth edges or create stylized images.
Successive flashing of strategically placed flash mechanisms results in shadows along the depths of the scene. This information can be manipulated to suppress or enhance details or capture the intricate geometric features of a scene even those hidden from the eye , to create a non-photorealistic image form. Such images could be useful in technical or medical imaging. To do this, smaller flash units typically vary the capacitor discharge time, whereas larger e.
Color temperature can change as a result of varying the capacitor charge, thus making color corrections necessary. Due to advances in semiconductor technology, some studio units can now control intensity by varying the discharge time and thereby provide consistent color temperature.
Some monolights display an "EV Number", so that a photographer can know the difference in brightness between different flash units with different watt-second ratings. These values determine the ability of a flash to "freeze" moving subjects in applications such as sports photography.
In cases where intensity is controlled by capacitor discharge time, t. Conversely, in cases where intensity is controlled by capacitor charge, t. Flash LED used in phones[ edit ] Flash LED with charge pump integrated circuit High-current flash LEDs are used as flash sources in camera phones, although they are not yet at the power levels to equal xenon flash devices that are rarely used in phones in still cameras.
The major advantages of LEDs over xenon include low voltage operation, higher efficiency, and extreme miniaturization. The LED flash can also be used for illumination of video recordings or as an autofocus assist lamp in low-light conditions.
Focal-plane-shutter synchronization[ edit ] Electronic flash units have shutter speed limits with focal-plane shutters. Focal-plane shutters expose using two curtains that cross the sensor. The first one opens and the second curtain follows it after a delay equal to the nominal shutter speed.
