intervalille

An intervalometer is a device used to control the timing of a camera's shutter release. It allows the user to set a specific interval between exposures, enabling photographers to capture a series of photos at predetermined time intervals. This functionality is particularly useful for time-lapse photography, where a long period of time is compressed into a short video, or for capturing events that unfold over time, such as scientific experiments or the changing of the seasons.

Intervalometers can be built into cameras or used as external accessories. External intervalometers often connect to the camera's remote shutter release port. They typically offer a range of settings, including the interval duration (from fractions of a second to hours), the number of shots to be taken, and sometimes even the duration of each exposure. Some advanced intervalometers also allow for programming complex sequences of exposures, such as bracketing a scene at different exposures or setting a start delay.

The use of an intervalometer is crucial for achieving consistent results in time-lapse photography, as it removes the need for manual intervention and ensures that each frame is captured with the exact same timing. This consistency is essential for the smooth playback of the final time-lapse sequence. Beyond time-lapse, intervalometers can also be employed for long-exposure astrophotography, where multiple shots are taken and later combined to reduce noise, or for capturing the subtle movements of clouds or water.
