I did some research on 3D gifs, which are basically two images which are positioned slightly away from each other (two different perspectives of the same subject). They are both edited together in which they flicker between the two, creating an almost holographic/3D depth to it.
I looked at some of the work from Joshua Heineman, who uses old photography and transforms them in order to create a 3D gif. The picture above proves how effective this style can be, in which it creates an edge to the picture, making use of the background and foreground which gives the image a sense of depth.
This method is basically a digital form of a stereoscope. A stereoscope is an object which was a form of entertainment in the 1800s onwards which allowed users to view two similar photographs through each eye. This gave the photographs a sense of depth, as the eyes would merge together a three dimensional image.
