I ran across this on another site and although it is not specifically photo related I thought some might be interested in seeing this. The gentleman has shifted the focus point of his shots in a time lapse series giving the visual impression of everything being in miniature. It appears both foreground and background are out of focus with only the center held sharp. I have a few 4x5 view cameras and I would like to see if I can duplicate the effort. I find it an interesting effect.
If you know how to use tilt or swing to increase the apparent depth of focus, simply use the opposite method to get that defocus affect. It does work better from a higher vantage point, though sometimes it can work from a level/even vantage. I have done a few of these, though the set-up is a bit slow. It also helps to have a lens with lots of coverage, since to really get a good effect takes more movement than more traditional set-ups.
The newest lensbaby that locks in place, and a d*gital slr with intervalometer set to take a frame every so often. Import file sequence into an effects program such as Motion or After Effects , enhance focus effect with blur filter in specific area, cast frame sequence to time, export as video.
