📷 English Bellows Camera: Thin-Lens Focus, Depth of Field and Exposure Lab

Rack the bellows of a Victorian field camera: the thin-lens equation sets the focus, the f-stop sets depth of field and diffraction, shutter and plate speed set exposure, and a swinging pendulum shows motion blur. The photograph is rendered with a real depth-of-field filter and a film response curve.
