PROJECT 22Repeating Camera Timer
THIS PROJECT WILL EXTEND the camera trigger hack project, allowing a timer to control both the focus and shutter release functions on a digital camera at an adjustable rate. This method of repeating time-delayed image taking is also referred to as “time-lapse photography,” and can be used to speed up time by piecing together hundreds of photos taken over the span of hours or even days. By first focusing the camera before the shot, the camera will be able to acquire moving targets with far fewer missed or blurry exposures. In this project, a timer feeds a 10-stage counter, allowing up to 10 individual control points, although only two are needed in order to control the camera relay interface.
