What is Pseudo Stereo 3D:The simple way to answer this question is to watch any 3D video with the glasses reversed. Making sure the left lens of the glasses is over the right eye. Most likely it will lead to visual confusion for many. But quite a large number of people do not know that they are watching reversed or inverted 3D. To make matters worse, depending on the actual scene there might not be anything “obvious” that is wrong, fooling even experienced stereographers. This is from witnessing it first hand while on location. More on that later.
