Time-lapse photography

When motion is a cinematic method to accelerate the long-term recording of movements, in which the frame rate of the recording camera is reduced in proportion to the playback frequency. Will the recordings be played at normal speed, the recorded process seems faster to run. This also changes are visible, which are in real-time due to their slow nature of man is difficult or impossible perceptible.

Technical Requirements

The inclusion of the individual film frames can be done with short sequences by hand, for long exposures of special separate switching devices (pulse ) and triggering magnets or frame motors are used. Better super 8 cameras often have this technique, which usually allow long exposures of the individual images. In the digital amateur segment is often found digital cameras and camcorders, which feature continuous shooting functions. Even without shooting functions are time-lapse recordings are possible by cutting out from the footage using video editing software frames at regular intervals. In the semi-professional range you can rely on SLR cameras whose recording interval is controlled, for example, with a computer. In professional fields, there are special cameras, especially for the film industry. With professional recording, make sure that always the same lighting conditions. This is in a controlled environment such as a photo studio still easily possible, depending on the recording interval in the open air, it is much more difficult. Are recordings with an interval of a few seconds even unproblematic, as the lighting conditions change not so fast, so there may be significant variations in brightness due to changing weather conditions during recording intervals of several hours to days. This is particularly visible for example on recordings, documenting the progress of construction of buildings. The annoying flicker can be reduced in post processing.


To all the settings that you need to create a time-lapse recording to figure out the following formula is useful:

Z = number of images; f = movie length ( in s); r = frame rate; a = recording time ( in s); i = interval (eg: make a picture every 2 seconds ).

The camera runs at 12 frames / second. When the film is projected at the normal frame rate ( for cinema) 24 frames / second results in a two times fast.
