New York Forest.5

Actual Elapsed Time: 1 year (31,500,000 seconds)

A forest in New York state undergoes dramatic changes over the course of a year. As the days get longer and warmer in spring, the snow cover melts and grasses grow. Buds form on the tree, waiting for the right moment to burst open into leaves. In this time-lapse sequence (sped up three million times) we can see that trees leaf out quite quickly (over just a few days). As summer approaches, the leaves become larger and greener. Then, as fall comes, the leaves change color- but not all at once. As the days get shorter and the temperature drops, snow cover returns.

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. Forty pictures from the set of 365 images were then selected and put together to form this video. Production: Bob Hone, Alan Berkowitz. Post-Production: Todd Reamon.
