This video -- a sort of dance using a slit scan technique -- was filmed using a Canon 7D SLR camera shooting at 60fps and then is played in slow motion. It is just really awesome. Yes, that is an English sentence.
Slit scan works in digital cameras by recording on a CCD (or set of CCDs) line by line. It is a natural artifact (as in this video of an airplane propeller), and it can also be created artificially on film -- in fact, in the cinema classic 2001: A Space Odyssey Stanley Kubrick used it to create the star gate sequence towards the end of the film. And that's oddly appropriate, for, while it may seem trite, since our understanding of the universe is tied to observation, and observation may so easily be distorted, what we understand as "real" and what is real may be substantially different. (That, BTW, does not mean there is no Reality or that observation and Reality are divorced, just that our embedded assumptions can be deeply flawed.)
The video above obviously uses artificial effects. The same thing -- well, a similar, less artful thing -- can be done with a smart phone.
The above video was recorded as part of the film "Cinematique." The videographers also point to a exhibition called XYZT where visitors see the effect in real time -- in fact, there's a really beautiful video of the exhibit here -- the slit scan exhibition is about half way through. And, in fact, there's yet another beautiful related short video involving dance and video effects called Hakani. I'm tempted to post separately on that and the whole XYZT exhibit, but, in lieu of that, for now here's simply another cool short video with slit scan effects:
