New York Forest.4

Actual Elapsed Time: 4 months (10,500,000 seconds)

In four months the landscape of this New England forest changes color completely. The green of summer makes way for the rich hues of autumn. This happens because the chlorophyll in plants breaks down as the days grow shorter and temperatures drop. Without chlorophyll, the substance that converts sunlight into sugars, the green color of the leaves goes away, revealing red, orange, and yellow pigments that were previously hidden. The leaves dry up and fall to the ground as temperatures continue to drop. Snow appears signifying that winter is in full swing.

How This Clip Was Made:

This time-lapse video was created from a series of still pictures. A 35mm still camera with an automatic timer was placed inside a box and mounted in front of the scene. The timer triggered the camera to take a picture every day. The images were digitized and transferred to a PhotoCD. Twenty pictures from the set of 120 images were then selected and put together to form this video. Production: Bob Hone. Post-Production: Todd Reamon.
