time-lapse photography

(Low-speed photography): 1904, Mary's students, French Bourne and Nogai invented slow photography. They found that the film obtained by shooting at a speed lower than the normal frequency reflected the action faster than the actual situation. This is slow photography.

The principle is the trick photography technique of shooting material changes or moving objects at the shooting frequency of 20 ~ 8 frames per second. If the shooting frequency is reduced and the projection speed is still 24 frames per second, a rapidly moving lens picture can be presented, giving the audience a sharp, tense and exaggerated atmosphere and impression.
