What Is an Intervalometer and How Is It Used When Taking Photos?

When talking about photography an ‘intervalometer’ also simply known as a ‘timer’ is a device which is used to automatically operate a camera’s shutter at specifically measured intervals of time. Intervalometers are widely employed in time-lapse photography where they are used to record a series of images at specific intervals over a period of time which are joined together in post processing to create a moving picture. Most intervalometers can be attached to a cameras micro-usb port (although some older cameras use proprietary connections) and allow automated capturing of images at a wide variety of intervals.
