By using the simple cross eye viewing methodology you can learn to see the depth in stereoscopic image pairs without the need of special hardware, although the technique might not be as easy and comfortable for longer use as using specialized hardware for 3D viewing. By following an easy tutorial and dedicating some time you’ll most likely be able to quickly pick up the technique to cross-view 3D content and to help you do that you can watch the video tutorial above prepared by Rhialto. The idea behind cross eye viewing of stereoscopic images is as the name implies by crossing your eyes, so that the left eye looks at the right image and the right eye at the left with the standard positions of the left and right images are reversed for that to work. You will learn to cross your eyes and focus in front of the stereo pair in order to fuse the two images into one that will have the stereoscopic 3D effect, so you’ll perceive the depth. This is precisely why when some stereo 3D images are presented for cross eye viewing they are labeled as such, because their left and right frames are reversed as opposed to normally the frame for the left eye being on the left and the right one on the right. You should be aware of the fact that most stereoscopic players photo and video do support the changing of the left and right frames inside a 3D photo or video, so you can easily switch them between parallel and cross-view format, even if they are not made for the one or the other by default.
