Pinhole Camera Project 2015 (Shutter Mechanism - Open)
Shutter Mechanism:
What I devised, in essence is called a Drop Shutter (also know as a "Guillotine Shutter"). It is a very simple and reliable shutter design and was one of the first mechanical shutters used in photography. When the button on the shutter release cable is pressed, a metal rod pushes down the shutter piece, moving it into the "Open" position. At the same time a small elastic band connected to both the shutter and a "bridge" piece becomes stretched. When the cable is released the rod will retract. Then the elastic band acts like a spring, pulling the shutter back into the "Closed" position.
