The difference between stereoscopic photography

The main difference is shooting with a special stereo camera, especially shooting people and moving scenes, especially traveling abroad, especially shooting stage performances. Four-lens stereo camera is small in size, easy to carry, low in shooting cost (using 135 film), reasonable in stereo depth of field design and clear in image, which is more widely used than five-lens stereo camera. After the film is scanned by scanner and printed by stereo synthesis software, almost all the skills of taking plane photos are available. However, considering the unique "three-dimensional depth of field" in stereo photo, that is, the control of crack point and the collocation of scenery, it involves complicated theoretical calculation to reasonably allocate the distance between foreground and background.
