I came across a burned building recently when I was out shooting. I took some shots of the interior and continued on my day. When I was reviewed my photos I noticed the point of view between two of the shots shifted just slightly enough to give the illusion of 3D. I made a .gif that quickly switches between the two images. It may be a little bumpy but the element of depth is unmistakably visible. I messed with this technique before, usually the foreground shift is a little less severe. I thought about making a whole thread with these fake 3D images, maybe something to work on when I get home.
