Abstract: Disclosed herein is camera mounting apparatus which is particularly useful for independently adjusting the interocular spacing and convergence distance between the respective optical axes of a pair of cameras used in three-dimensional (3-D) photography. Such apparatus comprises a pair of slider mechanisms, each including a slider member which is connected to a camera housing (e.g., via a camera support plate) and movable along a rectilinear path defined by its respective mechanism. One of the slider mechanisms is mounted for pivotal movement about an axis which perpendicularly intersects the respective paths of both slider members. Separate means are provided for (a) adjusting the positions of the slider members along their respective sliding paths, and (b) adjusting the angular relationship of one sliding path relative to the other, whereby the camera support plate is movable through a predetermined interocular spacing (e.g. 4.
