This time-lapse is a combination of two sequences of the same specimen but showing different perspectives. One used a Canon Digital Rebel controlled by a laptop running the program RemoteCapture 2.7 taking one frame every 3 minutes. The other was taken using a Nikon Coolpix 5400 controlled by a Digisnap 2000 taking one frame every 4 minutes. The sequence was shot over approximately 11.5 hours.
