Look this “aftermath shot” http://vimeo.com/1983046 , the guy say it was done mostly with just one fotograph.
How can we do this in blender ?
Use the foto as a texture on a plane and animate the camera accordingly. Then use compositor to edit in the FX shots.
Similarly:

Different techniques I think.
First one image mapped flat to a plane UV or otherwise, 2nd image mapped via camera projection onto a basic 3D model of a city?
