Hi, kibaris. I lift the whole tripod (or gorillapod) and move to the right. (In our living room, my wife just used a tabletop and glided the camera on its surface left and right. No tripod.) During post-processing, I crop off some to the left of one picture and some to the right of the other picture so they'll be roughly identical in centering the scene. I keep that in mind when I shoot -- that some portion on the left and right will be lost -- so I frame wide.
