Focus Stacking - 3
Some time ago I built a wooden flexure stage because I wanted to take focus-stacked macro photos. Originally the contraption was meant to be operated manually, but last week Sophia automated the thing as part of a homework project for her high school electronics class. An Arduino microcontroller drives a motor that advances the stage towards the camera in tiny steps, and a relay that triggers the camera. The size and the number of steps, and how much time the camera needs between steps to take a picture, are entered via an infrared remote control.
