Stereoscopic or three-dimensional photography is the technique capable of recording three-dimensional visual information or creating the illusion of depth in an image.
From the anatomical point of view, the human brain interprets the spatiality and "depth" of the image, comparing the two frames: that of the left eye with that of the right eye. The frames are "recomposed" in a single image, in the brain, and the superposition of the two perspectives gives us the feeling of "depth". Thinking at the macro level, the technique of recording stereoscopic images has remained the same. In order to create the impression of spatiality, a set of two images of the same frame is required, recorded with two cameras within a few centimeters of each other, in the same plane.
Having said that, I invite all of you to put on stereoscopic glasses and to be surprised at what you will discover. Enjoy!
