3D Images Without Glasses
Stereo photography, when combined with overlays and cellophane glasses, creates an off-kilter blue and red illusion that is commonly associated with 3D images. But this same style of photography, when converted into a two-frame animation, can create a similar illusion without the glasses or the unnatural colors. Jim Gasperini creates 3D art in this manner and produces images of Burning Man, among other things. This “wiggle” effect is quite powerful and adds a quirky element to the images as well.
