A test to see how I could do timelapse for drastically changing light over a long period of time, filmed from my hotel window in The Clift in San Francisco.
I too one photo every 20 seconds remotely with the intervelometer and it was auto iris, auto shutter and auto iso. Would it would or would it be too jumpy?
I think it works just fine, but in future I would have done just auto shutter as would have done the job for me the same and been cleaner at night.
Music is Ghosts by Nine Inch Nails.
Shot using the Canon 7D, a Sigma 10mm fish eye and the Canon power supply for the 5dmkII/7D
