Here is a time lapse that I shot while a storm was forming over Chicago. This is my first time lapse shot using my father's old FD lenses. Using a simple adapter from B&H Photo, I was able to use his old 75-200mm FD lens on my EOS-mount Rebel XT. After loading the image sequence into After Effects, I applied a simple curves adjustment. In other words, the soft attributes of the image are due to the lens. Check the links below for the mount, as well as an Instructable to show you how to use a TI-83 as an intervalometer.
