An apparatus is provided for producing a photographic image sequence showing an apparent movement of a camera in an x-axis direction, with respect to a filmed object, without actual movement of the camera along the x-axis. The apparatus includes (a) a camera fixed on a mount, which camera is rotatable with respect to the mount in a panning action about a z-axis running through a nodal point of the camera, (b) a horizontal platform for supporting an object to be filmed, said platform being rotatable about a z-axis running through a center of the platform, the z-axis of the camera rotation and the z-axis of the platform defining a yz plane, (c) a linear track of defined length for guiding movement of the camera mount along a y-axis lying in the yz plane, and (d) software for translating a resulting image sequence showing apparent unlimited movement of the camera along the x-axis, with respect to the object to be filmed, into synchronized simultaneous positioning instructions over a time sequence, for only the following three elements: (a) panning action rotation of the camera, (b) rotation of the platform and (c) a linear position of the camera mount along the linear track means in the y-direction only, without actual movement of the camera mount along the x-axis.
