The Nikon MT-1 intervalometer allowed completely untended time lapse photography. Its inbuilt intervalometer enables time-lapse photography. The built-in intervalometer (timer) can be used for time-lapse low-light movies. Most modern cameras include the most basic intervalometer functionality, the "self-timer". What is meant when someone refers to an "intervalometer" must be determined from context. This video was created using an intervalometer and over 3,000 still photographs. The unit also contained a built intervalometer for delays up to 1 frame per minute. For instance, an intervalometer might activate something every 30 seconds. Using an intervalometer permits restricting the pictures taken to only those with the desired content. Strictly speaking, an intervalometer only measures, and/or signals, time intervals.
