Abstract: A portable slating device comprises a light-tight housing having a lens on the front thereof and a copyholder on the rear thereof. When the lens on the front end of the housing is positioned adjacent the lens of a movie camera whose scene takes are to be identified by slating information, the housing lens functions as a supplementary close-up lens cooperating with the camera lens to sharply focus the information in the copyholder onto the film in the movie camera. When the filming of a scene-take starts, the operator closes a switch for simultaneously energizing a synchronizing light bulb located within the housing and an audio signal device mounted on the housing to provide for synchronizing the visual action of the film with the sound track.
