A view out my office window. Not a terribly engaging view, but this was shot over 27 hours. (Details below.)

Details: I put a Canon EOS 1D Mark II N with a EF 16-35 mm f/2.8 L USM lens on a tripod and pointed it out my window. The camera was powered with an AC adapter (so I didn’t have to worry about the battery dying) and tethered to a laptop running Canon’s EOS Utility. I programed it to take one photo every minute and left the camera in aperture priority mode. The only hiccup was the overnight time exposure grew to longer than one minute, so it started skipping minutes. The music is a generic loop created in Garage Band and the editing was done in Final Cut Pro.

Things I learned: I needed to shield the lens better, as it picked up reflections in the window’s glass. A little gaffer’s tape and some black cloth would have solved that. After the first few test frames I removed the screen from the window – with the wide angle view and extensive depth of field, I was seeing the pattern of the screen in the frames.
