Michael Wesely is a German photographer who has a series of polaroid multiple exposure photos, which span a three year time period. I'm a big fan of polaroid photography because of how raw the pictures tend to look. I really love this one because you can see the renovation and expansion of the MOMA over the years, while everything else around it stays completely unchanged. You can also see the streaks of the sun's rays in the sky which adds to the time lapse effect. I have recently learned how hard it can be to do a multiple exposures with a polaroid 680 camera. Although it is never mentioned the kind of camera and technique Wesely used, I can only imagine the difficulties that would come with three years of an open shutter.
