Photo Flashes

from All

Product description

A flash is a device used in photography producing a flash of artificial light (typically 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 flash units as of 2009 are electronic, having evolved from single-use flash-bulbs 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 (hot shoe).

In professional studio equipement, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains and synchronized with the camera from either a flash synchronization cable, radio transmitter, or are light-triggered, meaning that only one flash unit needs to be synchronized with the camera, which in turn triggers the other units.
