ABSTRACT:
A method for determining the spacing between adjacent vantage points for taking a 3-D photograph which involves computing the desired spatial parallax in accordance with the following formula: ##EQU1## where P is the desired spatial parallax, V is the viewing distance and E is the capability of the eyes to fuse the two images together expressed in terms of arc minutes of the scanning angle and utilizing results of this computation to compute the distance T between adjacent vantage points in accordance with the following formula: ##EQU2## where B is the distance between the camera and the background object and K is the distance between the camera and the key subject and u is the back focal length of the camera lens. A calculator has been provided for making the necessary calculations.
