Time Lapse
In order for the human eye to discern a fluid video or cinema sequence without any jerking, a film must scroll at a rate of 24 frames per second. To achieve this scrolling speed, producers must use time lapse. This technique, also known as chronophotography, involves performing a "accelerated effect" on a large series of shots taken in one place, at regular intervals, to see their evolution and changes. The purpose of the time lapse is to assemble the photos, from the first to the last, at a rate of 24 frames per second. In fact, time lapse is an illusion of time (accelerated) resulting from a quick scrolling of images.
The equipment needed to make a time lapse:
- A camera: essential equipment for manual control of the exposure as well as the white balance. The camera is the most commonly used professional tool for an accelerated effect, but thanks to the evolution of technology, some smartphones with very sophisticated features also allow to perform this Operation.
Similarly, a spy camera or a hunting camera also offer the possibility of completing a time lapse since these devices are equipped with very advanced technology.
- A tripod: this material is necessary to avoid a change of framing that would make it difficult to time lapse.
The hyperlapse technique:
A variant of the time lapse, it differs from the latter by the fact that it uses a different technique on the movement as well as on the position of the camera when capturing the shots. Hyperlapse does not occur in a fixed location. The camera is in motion and the shot is taken over very long distances.
