A time-lapse camera is a specialized device or camera setting that captures a sequence of images at specific intervals over an extended period, which are then compiled into a video to show a scene unfolding much faster than in real time. This method compresses hours, days, or even years of real-time footage into seconds or minutes, providing a unique way to visualize slow processes or subtle changes that are not immediately noticeable. Such apps are useful for tracking slow processes, like the setting sun, construction projects, or plant growth.
