Photographs by Joseph Foldes You c:an make either a wide-angle or telephoto pinhole camera. Area covered depends on film-to-pinhole distance. Both pictures were made from same position; left, picture made on camera with pinhole 8Y2 inches from film, and right, shot with pinhole 3 inches from film. Here's the completed camera 1 2 3 47
together forming a light-tight unit. The front, smaller box, has a small hole in it which acts as the lens. A piece of film is placed inside the back of the rear box either by using tape or the more elaborate slot system. (Loading must be done in complete darkness, of course.) How does the pinhole act as a lens? Theoretically, t~le pinhole is so small that it admits only one ray of light from any given point on objects in front of the camera. Light rays enter the pinhole from all points and form an image on the inside of the camera. The sharpness of the image depends on the size of the hole. The smaller the hole (aperture), the sharper the image. First, let's consider plans for making two types of pinhole camerasthe simple one-shot, and the sheetfilm-type camera, and second, how to take indoor and outdoor pictures with them. (If you own a press-type camera and don't want to go to the trouble of making the box, you can turn this camera into a pinhole type by substituting for the lens a piece of aluminum foil with a pinhole in it. The foil can be fastened over the opening on the front standard of the camera with black photographic tape to insure against light leaks.) A plan for the simple one-shot camera appears on page 46. ''''ith this camera only one picture can be taken during a shooting session. The photographer using this pinhole camera must go into the darkroom or use a loading bag to unload and reload before making another shot. The hinged back allows for easy loading of sheet film, and is extra protection against light leaks. Once you have cut out the pieces of cardboard, blackened them on the inside with diluted India ink, and assembled them into box form, you are (Continued on page go) How to build a pinhole camera for use with film packs Pinhole camera with film pack back allows photographer to shoot more than one negative during a session without running to darkroom. Three boxes (right) must be constructed. Inner box fits into back (illustrated opposite page). Front fits over these boxes. String or rubber band holds wlits together. Pinhole is made as illustrated on page 46 and taped inside the front box. Inner Box Back Front 48
