I recently purchased a
Nikon D90 and have been eager to delve into the world of time lapse photography, especially after being introduced to the work of
Keith Loutit. Since the D90 doesn't have a built-in interval shooting mechanism, I bought a
digital shutter release on ebay. It's great and I highly recommend it. There are no limits on how long you can shoot for and everything is customizable.
I did my first experiment out the window yesterday. This is 400 shots with 2 second intervals.
