Walden.1

Actual Elapsed Time: 2.8 hours (10,000 seconds)

Amid the frantic scurrying of sunbathers and tourists, the sun sets over Walden Pond, creating a colorful close to the day. Normally, we can't see the motion of the sun in the sky. By speeding up the action to 1,000 times normal speed, we can not only see the sun move across the sky but we can also see the clouds change as the air cools in the late afternoon. During the middle of the day, the air is fairly still and high clouds form as warm moist air flows up from the ground. By late afternoon, the wind increases and causes the clouds to churn as they move across the sky.

How This Clip Was Made:

This time-lapse video was created by shooting 2.8 hours of regular video. Only 1 of every 1,000 frames of video was digitized and transferred to a computer. When displayed, the remaining frames show the action at 1,000 times normal speed. Production: Bob Hone. Post-Production: Brennan Doyle.
