A digital camera external flash is add-on equipment that helps provide versatility and power when compared to a built-in flash.  Like all camera flashes it creates an artificial source of light; however it is not permanently attached to the camera.  Instead, it fits onto the camera through a hot shoe which is typically a slot on top of the camera that allows the camera and the external flash to sync.  The external flashes use their own batteries, rather than take power from the camera itself.

An external flash also features both an automatic and a manual setting.  This allows the user the same options as with a built-in flash, but with the more capable external flash.  Many digital camera external flashes come with a built-in or attachable diffuser to help tone down harsh lighting and help expand the flash coverage when taking wide-angle shots.  Some external flashes come with heads that can be swiveled or tilted, allowing for more creative uses of the flash.  This can also go a long way in helping to create the perfect picture.  Others even have zoom heads that can change to match the focal length of the lens of the digital camera.

An external flash is really a sensible option to consider when trying to obtain quality photos and when making creative photos.  It can help bounce back the light to help eliminate red eye if directed to a reflective surface or specially designed reflector.   It can recoil the light off nearby white walls to produce better side-light.  This can help create color rich images with more natural lighting.  The added power also increases the range of the flash, allowing you to take more photos from a distance when lighting is an issue.
