This is the very first image projection inside the camera (camper). I put up a large paper screen on the wall, and have made a small hole on the opposite wall. The image was captured with an Olympus OM-D E-M5 digital camera, 4 seconds exposure at f.4, iso 6400. Lens Panasonic 7-14mm. Digicam placed a little below the hole inside the pinhole camera.
The aperture opening of the pinhole camera is approx f:200, distance between hole and screen a little more than two meters. It seems to work out pretty well this far. Now I need to clean up a little, cover every small light leak, paint it black inside and make a more permanent image screen inside.
