Right and left projected image fields of stereoscopic images must have even illumination. If audiences are subjected to uneven illumination intensity of right and left pairs of stereoscopic images, the result for most people will be discomfort. Complimentary colored filters are used in the optical paths of the right and left projected fields, and the resultant additive color mixture is used for evaluation of symmetrical illumination. A means is thus presented for quickly, accurately, and inexpensively calibrating right and left image fields for both equal and even illumination intensity.
