A timelapse is a short video that allows to reveal the evolution of a series of events, invisible to the eye. This photographic technique makes it possible to follow the evolution of an object over a long period of time. Whether you want to follow the evolution of the Milky Way in a clear nightsky, the construction of a building, or the layout of a sports arena or a performance hall, you can see in a few seconds the evolution of an event normally too long to be perceived by the human eye. A few examples :
