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.

When it comes to low light photography, especially night photography, there are a variety of things that all combine to making it difficult to take a good picture.  This is true for the amateur and the professional photographer.  The low light will necessitate either a flash or that the shutter remain open longer.  The flash itself can whitewash the objects in the foreground of the picture, ruining a photograph, especially if the subject of the picture is further away.  The very bright foreground will simply detract from any appreciation of the subject of the picture.  If a flash is not used, then the shutter will need to stay open longer, which means that the camera will need to be held very steady.  If there is even the slightest movement then the picture will turn out blurry.

There are ways around this however.  Understanding the basic operation of the camera is a must.  Knowing at what shutter speeds to operate and what setting the aperture should be on will go a long way in helping to take those good low light photographs.  Also, knowing when to use a flash and when it will just make everything in the foreground appear overly bright is important.    A little more skill and practice will also help in recognizing where the light sources are and how they will interact with the subject of the photograph.  Additionally, accessories can also go a long way in helping to take those great night shots.  A tripod will hold a camera steady, making sure that the photo does not turn out blurry because it moved slightly.  Also, an external flash can help with advanced features and greater range.
