CameraControllerApi
The CameraControlerApi is an attempt to control a DSLR via REST functionality. At the moment is it possible to change the camera settings (ISO, aperture, time), take pictures and stream the live view of the camera (only tested with a Nikon D90).

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
