High speed camera sex
For example, an image of a scene may be captured once every second, then played back at 30 frames per second; the result is an apparent 30 times speed increase.
In a similar manner, film can also be played at a much lower rate than it was captured at, slowing down fast action, as slow motion or high-speed photography.
Pillsbury owned the Studio of the Three Arrows in the Valley and applied the technique to solving the problem of ensuring the survival of the rapidly shrinking varieties in the meadows.
The United States Cavalry, then in charge of Yosemite, were mowing the meadows to produce fodder for their horses.
Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence.
His films were shown during his lectures, which were scheduled first at garden clubs around California and then at most of the major universities across the country.Pillsbury showed his first film to Superintendents for the National Parks during a conference held for them in Yosemite from October 14–16, 1912.The result was a unanimous agreement by the Superintendents to cease cutting the meadows and begin preservation.Pillsbury also showed his films and lectured to town hall forums and the National Geographic Society.
In 1926 he was asked to present both his lapse-time motion pictures and his newly invented microscopic film to President Calvin Coolidge at a dinner given on March 15 in the President's honor at the Willard Hotel in Washington DC.
Starting in the 1930s, Ott bought and built more and more time-lapse equipment, eventually building a large greenhouse full of plants, cameras, and even self-built automated electric motion control systems for moving the cameras to follow the growth of plants as they developed.
