I was shooting in downtown Toronto during the APUG conference and was setting up a shot with the CN tower in one corner when I hit against the problem of how to avoid the (usually) ugly distortion of curved objects not placed dead center with the use of wides. I was looking at the ground glass and the weird shape I'd distorted the top of the tower into when a possible solution hit me. I reframed the shot with the tower dead center, which got rid of the distortion, and then used shift to get it back to the right position within the composition. Now this may have been a "duh" moment on my part, but I honestly half expected it not to work, and for the curves to go loopy on me again as I shifted ...but of course they didn't. And mediocre final photo notwithstanding, it kinda tickled me. So let's hear it -- what other not so obvious uses have you found for camera movements? I've also used shift or rise/fall to use light fall-off to good advantage, but there must be other uses I haven't thought of.
