The Loreo lens cap lets the photographer snap two images in the same physical photo. Each image represents what the left/right eye see. From there, it should be possible to create a stereo image. In this case, you will need a “3D viewer” to visualize the 3D photo, which doesn’t seem all that exciting. At least, it’s not too expensive: the cap sells for less than $100. Product page.
