They’re a hallmark of horror movies, sci-fi, the 1950s, and the 1980s. 3D Glasses are a familiar site for anyone that’s ever seen a drive-in, a late-night horror movie marathon, or a b-grade sci-fi movie. The distictive red and blue (or red and teal, realistically) lenses serve to allow you to perceive the depth of an image, by separating it into two color layers that your left eye and right eye see individually.
To create a 3D Image, you simply need two images with the same basic viewpoint, spaced apart at roughly the same distance your left eye and your right eye are apart. The angle you see depends on the orientation of those two pictures. For instance, for a normal viewpoint you’ll want to keep the eye viewpoints level horizontally. Past that, it’s just tweaking the depth of the 3d image by moving the layers right and left and working with the transparency levels to get an appropriate image. I’ll leave the instructions to the pros, but those are just a couple of helpful tips.
