Flash
Flash is used to provide additional or directional light when capturing an exposure. All cameras have an auto flash setting that will fire whenever the camera thinks flash is required, but there are a number of other flash settings available to suit different shooting scenarios. These include Red-eye Reduction flash for countering red-eye, and the softer Fill-in Flash for enhancing daylight shots that might otherwise be silhouetted. Some compacts, and all DSLRs, will also have a hotshoe for attaching an external flash unit.
