Pinhole cameras made out of hollow eggs

Francesco Capponi made these beautiful pinhole cameras out of blown eggs, shooting eerie negative photos that could only been seen by destroying the camera:

Take the egg and drill it with a rotary tool (I used a Dremel) in order to obtain a square hole (2cm). At this point, usually, you will find yourself covered in egg juice. Before washing yourself be sure that the egg' shell is empty. Wash yourself and the interior of the egg. In a dark room paint the interior of the shell with the emulsion, in order to make it light-sensitive.

Now block the opening with a wrought-brass pin-holed plate, trying to restore the natural egg-ness of the shell. With the black tape seal the structure. You'll notice that the shell is really transparent: to avoid any problem, wrap it with the black cloth, carefully leaving out the pinhole. During each stage of this process the egg could break. Usually it does.
