Making a pinhole camera

The diagram shows the basic structure of a pinhole photographic camera. The trunk of the photographic camera is a cardboard box that is open up at both ends. To make this box, cut a rectangle of cardboard that measures 5 3/4 inches by 2 inches.

Separate the long edge of the rectangle into four equal sections. as shown. Use your knife to score the paper-thin along each of the lines. Fold the paper-thin along the scores to make an open-ended box.

Before you tape the edges together to make a box, you need to make the interior black to minimize reflection of light within the photographic camera. You tin can cutting a piece of black paper and fold it to make a black lining for your box, or you lot can cover the inside surface of the cardboard with strips of black tape. Yous could also paint the inside apartment black with spray paint or tempera.

Now tape the edges together to make a box, and tape all the box's edges and corners to foreclose lite from leaking into the camera.

Insert the box into the film cartridge equally shown. It should fit tightly. When yous hold the open end of the box up to your eye, y'all shouldn't see any light leaking in where the box fits into the cartridge.

To make the front of the camera, cutting a rectangle of paper-thin that measures about 1 3/4 by 3 inches. Cut a square hole that measures about 1/2 inch past i/2 inch in the center of the rectangle. Line the inside of the front end of the box with black paper or tape, leaving the hole open.

Tape a ane-inch foursquare of aluminum foil over the square hole, and make a small-scale pinhole in the eye of the foil.

When you aren't taking a flick, yous demand to cover the pinhole with black paper. We fabricated a shutter that slides into blackness paper guides. as shown.

To ensure that no lite tin can leak in, tape the box to the front with black tape. Spike the camera to the cartridge with rubber bands, as shown.

Taking photos with your pinhole camera
