An on-camera flash light is an external flash unit mounted in a camera’s hot shoe, which is a mounting point located on the top of a camera. A flash is used is to illuminate an object when the ambient light is too low to take an image. Often called speedlights, on-camera flashes are designed to extend flash range beyond that of the camera’s built-in flash. Hot-shoe flashes produce an immense amount of light that is great for shooting indoor events, or for adding fill light for shooting outdoors. They not only have a higher light output than built-in flashes, but also can be tilted and rotated, allowing photographers to use the light more creatively and effectively. Bounce the flash off ceilings or walls to deliver indirect lighting for shadowless illumination. The angle of light output can be adjusted far enough away from the optical axis, which helps avoid producing red eyes and blown-out highlights.
