This is a simple walk-in pin hole
camera that I use to show my classes the camera obscura effect. I
built it out of a few sheets of 1/4" OSB and a few 2x4's.
This pinhole camera is at the Penland School of Crafts near Spruce Pine, NC. It was made by the artists Clara Couch and Pinky Bass. The structure is ferro cement, built in the shape of a pregnant belly, with the belly button as the pinhole.
