ABSTRACT:
An orientation indicating device visibly indicates, preferably in the viewfinder of a camera, that the camera is deviated improperly from its normal horizontal position for picture-taking. The device comprises a pendulum controlled indicating circuit including electrically activated display means for indicating before a picture is taken that the camera is deviated inclined-left or inclined-right from horizontal, and therefore the picture should not be taken.
