Replacing a simple and inexpensive remote cable release for your camera with Raspberry Pi may seem like a classic case of over-engineering, but using the tiny machine to control the camera opens up a whole new world of photographic opportunities. Using a simple Python script, you can turn Raspberry Pi into a powerful and flexible intervalometer or trigger the shutter using sensors connected to the computer. Add to Raspberry Pi a Python-based web app, and you can control your camera from any computer or mobile device.
