Pinhole
The oldest imaging method around and certainly the airiest. Pinhole cameras are not only a move back to its source, but also encourage the discovery of slowness, using shutter times of up to 470. From the cardboard do-it-yourself kit, to hole shutters for conventional cameras and 8x10" Shift-Woodcamera you will find many possibilities for the trip back to the beginnings. Guaranteed without ultrasound auto focus mechanism.
