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.
Digital video cameras use the same image sensing methods as still cameras, but in addition to storing the images digitally, they output NTSC video for playback on any TV. See digital camera features, flash memory, photo sharing site, photo editor, photo scanner, X3 and DSLR.
