provided with each electronic flash unit. Information packaged with film may also provide guide numbers appropriate to their speed in regard to the various powers of electronic flash units.
Electronic flash.
Light source based on electrical discharge across two electrodes in a gas-filled tube. Usually designed to provide light approximating to daylight. It is often regarded as artificial light souce in the dark.
Electronic flash
A small device usually built into digital cameras that emits a brief burst of light to illuminate poorly lit scenes. Light source based on electrical discharge across two electrodes in a gas-filled tube.
Electronic flash vs. tungsten halogen, etc.
There are distinct advantages to using electronic flash (strobes) as opposed to tungsten halogen lights (the type used for video). The electronic flash gives a very brief, intense flash of light.
Electronic flash
Designed to provide light where the lighting on the scene is insufficient. Electronic flash requires high voltage, usually obtained through batteries and a voltage-multiplying circuit which discharge a brief, intensive burst.
ELECTRONIC FLASH - Artificial light source produced by an electrical discharge traveling between two electrodes through a gas-filled tube. The light from electronic flash is approximately the same color as daylight.
Electronic flashes are a simple, cheap solution to this inherent problem in photography. Their sole purpose is to emit a short burst of bright light when you release the shutter.
Electronic Flash, and More
When using studio strobes or flash, a handheld meter always makes a big difference in results. Many meters can trigger flash remotely or via a sync cord to make readings, again from subject position.
Electronic flashguns
Flashguns vary in their angle of coverage and output. They may be powered either by ni-cad rechargeable batteries or dry calls.
Electronic flash (strobe). A camera accessory that provides a brief but powerful flash of light. A battery-powered unit requires occasional recharging or battery replacement.

The electronic strobe, invented by Doc Edgerton in 1931 at MIT, was a great scientific instrument, helped win the war against Germany by facilitating night aerial reconnaissance photography, ...
Electronic Flash, Strobe (stills)
An electronic source that produces a burst of light capable of freezing motion. Its Color Temperature approximates daylight.
-Electronic flash - artificial lighting produced by an electronic discharge in a gas filled tube. A single tube can produce a large number of flashes.
-Electronic shutter - shutter system timed by electronic rather than mechanical means.

Electronic flash has come a long way since Harold "Doc" Edgerton, an American researcher and inventor, made modern electronic flash photography a reality in 1931.
Automatic electronic flash is so convenient and easy to use that you are usually unaware it even fires. With your camera on automatic, it's always ready when your autoexposure system decides it's needed.
During WWII electronic flashes giving light from electronic gas-discharge tubes were developed.
Slow-sync. An electronic flash technique for using the flash at a slow shutter speed, which allows background details to show more clearly.
There are times that an electronic flash can be used to overcome problems in natural light to control contrast between highlights and shadows in a scene. In strong light there can be several f-stops difference between highlight and shadow areas.
Insect Close-Ups And Electronic Flash Exposures
The insect photographs that were done between 1974 and 1986 were lighted by one or two flash units and done without the use of through the lens flash metering or automatic flash exposure metering.
The camera's now had electronic flash, auto-focus, motor drives, good lenses and other enhancements that made it easier to take pictures of objects, people and motion.
6 focus-free lens, a built-in electronic flash, a large viewfinder plus an external viewfinder attachment. It's sealed with a silicone O-ring and is rated to a depth of 100 feet.
Photo 1 of Steve Runnals was made with an electronic flash (in an umbrella) in a studio against a white background.
A problem peculiar to taking portraits with any type of electronic flash is the phenomenon known affectionately as "red eye," the somewhat satanic red glint in subjects' pupils often seen in photos.
An Electronic Flash Unit that is made to be used directly with a specific make or model of a camera.
Electronic flash guns which sense the light reflected from the subject, and cut off their output when they have received sufficient light for correct exposure. Most units must be used on or close to the camera for direct lighting only.
Hot Shoe: A standardized method of mounting an electronic flash on a camera. The hot shoe fittings on both the camera and flash have an electronic contact in the center that fires the flash when the shutter is pressed.
Generic term for electronic flash.
Stroboscopic Flash
Stroboscopic or Repeating Flash is a 'mode' available on some flashguns where under certain lighting conditions it can produce multiple exposures in a single frame.
Dedicated Flash - Describes an electronic flash that is made to be used only with a specific model of camera.
Recycling Time The time necessary for an electronic flash to recharge and be ready for the next picture, it often depends on the type and condition of the battery and the guide number of the flash.
Flash sync is used to describe either the connection point where you plug an external electronic flash into your camera (usually a PC port or the camera's hot-shoe), or the fastest shutter speed your camera can 'sync' with an external flash.
Red-Eye - An effect caused by an electronic flash reflecting off of the human eye and making it look red. Compact cameras with the flash located close to the lens suffer the worst from this problem.
His book, "How to Select and Use Electronic Flash" was published by HP Books of Tucson. He also contributed to the Book, “The Photographic Flash - A Concise Illustrated History', published in Switzerland.

Flash
Nearly all digital cameras come with a built in electronic flash to add a burst of extra light in low light conditions and other situations.
Focus
To move the lens manually or through autofocus for a sharp photograph.
Unit used to quantify the light output of electronic flash. A joule is equal to one watt second of 40 lumen-seconds. The measure is used to compare flash units in terms of power output.
