Methods and apparatus for aiding a photographer in determining, coordinating and adjusting numerous variables which bear on the quality of a stereoscopic picture employing a lenticular screen. The variables may include, depending upon the photographic method employed and the scene to be photographed, the desired size of the stereoscopic picture, the resolving power and lenticule width of the lenticular screen, the number and size of two-dimensional picture negatives which are taken and included in the stereoscopic picture, the distance between adjacent camera vantage points from which the negatives are taken, the camera focal length, the distance from the camera to the nearest element or object of the photographed scene, the distance from the camera to the farthest element or object of the scene, and the distance from the camera to an element or object - the "key subject matter" - in the scene which is to lie in the plane of the stereoscopic picture.
