1. PINHOLE PHOTOGRAPHY

2. WHAT IS PINHOLE PHOTOGRAPHY? Pinhole photography is lensless photography. A tiny hole replaces the lens. Light passes through the hole; an image is formed in the camera

3. HOW IT WORKS

4. We see things because light rays reflect off of them and these reflected rays form an image on the retina. A camera is a mechanical eye. pupil = pinhole eyelid = shutter retina = film HOW IT WORKS

5. CHARACTERISTICS OF PINHOLE PHOTOGRAPHY Pinhole images are softer – less sharp – than pictures made with a lens. The images have nearly infinite depth of field. Images are exposed on film or paper – negative or positive; black and white, or color.

6. Pinhole images tolerate little enlargement. To get clear, sharp pictures, the camera must remain very still while the shutter is open. Exposure time varies in length ranging from half a second to several hours. CHARACTERISTICS

8. A pinhole camera is a small, light-tight can or box with a black interior and a tiny hole in the center of one end. You can design it to accept roll or sheet film. The two ends of the camera are parallel. The end opposite the pinhole is flat so that the film is held in a flat plane. The pinhole has a cover to prevent light from entering the camera when you aren't taking a picture. PINHOLE CAMERA

9. Pinhole cameras may have one pinhole or several. Multiple pinhole cameras produce overlapping images or, with certain designs, panoramic images. PINHOLE CAMERA
