I've seen this effect in several documentaries - where they took a flat photo, and instead of just panning or zooming on it, they do something to make the photo seem 3D - where the subject moves relative to the background.
You can see it in this trailer for the movie "We Are Legion" at 1:10:

What kind of software are they using to accomplish this?
Also saw it used extensively in the great documentary "Sound City" by Dave Grohl.
