A camera stand for directing a video camera at, alternately, a room scene and a document scene, where the document in the document scene is oriented to be read by a person seated in the room scene, featuring a supporting arm and a rotatable connection connecting the video camera to, and supporting the video camera at a supporting end of, the arm. The rotatable connection allows the video camera to be alternately rotated between a position directed substantially vertically down at the document scene and a position directed substantially horizontally at the room scene. The rotatable connection has a rotation axis inclined at substantially a forty-five degree angle to the vertical, and is connected to the arm so that the video camera rotates from viewing the room scene right-side-up to viewing the document scene right-side-up.
