Now, one might be wondering how these types of 3-D presentation work. Each way is different, while producing much of the same effect. Stereography uses one or two cameras. Then, another picture of the exact same scene is taken, only it is taken exactly 6.5 cm to the left or right, because 6.5cm is the general distance between a human's pupils. This creates depth, which your eye converts into a wonderful 3-D picture.
Anaglyphic photography overlaps the pictures from the very beginning.
However, these two pictures are filmed in different colors, red and green. This forces each eye to only see what picture it should see, having mostly the same effect as stereography. Polarization is exactly like anaglyphic 3-D, only it uses polarizing filters instead of color filters. Instead of using red and green to direct your eye, it uses vertical and horizontal light wave filters, having, yet again, much the same effect.
