A roll-film Polaroid camera
In fifteen to twenty minutes you can convert any roll-film Polaroid to shoot 120mm medium-format film. Medium-format film produces a negative almost four times larger than 35mm film, which means you can make much larger prints of the image without losing quality.
Instructions
1. Remove the back panel from the camera.
2. A drill bit
Use a 1/4" drill bit to drill a hole at the bottom of the film chamber on the right. This where you are going to insert a bolt to make the winding shaft.
3. A bolt
Screw a bolt that is 1/4 inch in diameter and 1 1/2 inches long into the hole you just drilled at the base of the film chamber.
4. Attach a knob to the bolt so you can crank the winding shaft. You can pickup a generic 1/4-inch knob at a hardware store.
5. Make two shims by folding torn construction paper into two small wedges. Use the shims to prevent the film canister from moving around in the left film chamber.
6. Use a 7/16-inch drill bit to drill a hole in the pressure plate.
7. Cover the hole you just drilled with a piece of clear red glass or plastic. Use a small piece of clear plastic tape to secure the glass.
8. Insert 120mm medium-format film into the camera.
9. Cover the back of the camera with a piece of black cloth to prevent light leakage. Use a thick black cloth that does not let any light through and make sure it completely covers the back of the camera.
