New York Forest.1

Actual Elapsed Time: 17 minutes (1,000 seconds)

A mist shimmers in the early morning light falling on a New York forest. At normal speed, this scene would seem quiet and still. Only by increasing the speed of this clip 100 times can we see how the mist shifts and moves. Upward air currents cause the mist to shift back and forth. As the sun rises it heats up the ground, which in turn, heats up the air right above the ground. As the warm air rises it picks up some of the mist and carries it skyward. Eventually, the air warms up enough to evaporate the mist.

How This Clip Was Made:

This time-lapse video was created by shooting 17 minutes of regular video. Only 1 of every 100 frames of video was digitized and transferred to a computer. When displayed, the remaining frames show the action at 100 times normal speed. Production: Bob Hone. Post-Production: Brennan Doyle.
