Three pivotally interconnected arms are pivotally and slidably connected to a frame which is slidably connected to a base. One of the arms supports a camera thereon. The arms are pivotal to the left and to the right to reformat a camera view from horizontal to vertical or vice versa. The base slides with respect to the frame to eliminate horizontal parallax error. Vertical parallax error can be compensated for by elevating the arm supporting the camera.
