The second panel is actually two separate stills from the movie (one from the beginning of a pan and the other from the end of it) and spliced together so it looks like the whole area was in the shot at the same time. The pillar in the middle provided a convenient seam for the edit, but some blending was still necessary, as by the time the pillar had moved from one side of the shot to the other, the lighting on it had changed considerably.

Next week will feature a couple more composite frames like that.
