lens stereoscope

From the stereo principle, dual-lens cameras can shoot stereo photo, but in order to make the stereo observation more extensive and more realistic, civil stereo cameras are all multi-lens, such as three-lens, four-lens, five-lens and eight-lens cameras, but the price is amazing. There are four plane photos taken from different angles in the stereo photo made from the negatives taken by a four-lens camera, and the effect is equivalent to that of a five-lens camera, so it is easier to popularize. However, the three-lens camera has few lenses, the lens spacing is too short, and the effect of large-scale digital production is too poor. Except for making small-scale optical films, it cannot be popularized. We have samples taken by various stereo cameras for comparison. Stereophotography mainly applies the binocular parallax principle, telling us that a three-lens stereo camera can form three image pairs, and a four-lens stereo camera can form six image pairs. The more graphic pairs, the more information can be accommodated. Therefore, the stereo photo synthesized by four shots is more natural, lifelike and gentle than the stereo photo synthesized by three shots. The photos taken by the four-lens camera can be enlarged to more than 12 inch, and a large grating stereo photo will be given when you buy the camera.
