Stereo photography method

The object-image distance of orbital stereo photography should be determined according to the sliding track, which is usually set by the designer. Usually the distance between the subject and the lens is controlled at 2.5-3.5 meters, and the distance between the foreground and the lens is controlled at about 0.9-2 meters. 1. First, set the camera to the middle position, set the camera function, focus and aim at the subject, then move the camera to the locked position, start the slide rail, start shooting, and then select the photos taken on the computer. Generally speaking, it is better to take a picture in the middle, because there are unstable factors when the camera is turned on and stopped at the end. If the camera takes more photos at a time, in order to increase the parallax, we can keep every other photo, every other two photos or even every third photo as a three-dimensional online map. On the other hand, if you want to reduce parallax and enhance the clarity of the subject, you can keep photos continuously or every other photo. 2. You can use the scale on the slide to mark both sides at the distance from the center with a shooting interval of 6 mm-50 mm, and then move the set camera from left to right or from right to left to the mark for exposure, and the obtained photo is a three-dimensional circuit diagram. If this method is properly mastered, parallax can be better controlled at will. When representing the same subject, the greater the shooting interval, the stronger the stereoscopic impression, but the lower the definition. If it is beyond the resolution range of the grating, it will cause the image to be blurred and the grating line cannot be matched, thus causing visual discomfort. Parallax control of stereoscopic shooting is the same as stereoscopic painting, and the shooting interval can be increased for large, round and plump objects. For fine and complicated textures or vertical lines, the shooting interval can be appropriately reduced to keep the subject clear.
