The BattleTag is a player-created name that serves as your Battle.net title. It is used in all Blizzard games, as well as on their forums and community websites. Players create a name of up to 12 characters, and this becomes their official title on Battle.net. Your BattleTag is what other players see on your Diablo III characters, and what appears on their Friends List.
A digital camera records and stores photographic images in digital form. Many current models are also able to capture sound or video, in addition to still images.
A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras.In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor.he alternative would be to have a viewfinder with its own lens, hence the term single lens for this design. By using only one lens, the viewfinder of a DSLR presents an image that will not perceptibly differ from what is captured by the camera's sensor.
