Can a photograph be taken with a camera without a lens?

Yes, one can use a pinhole camera. It is a camera without a lens. An extremely small hole takes its place, which should be in very thin material. An image's light from a scene passes through this single point, the image on the light-sensitive material will be upside-down, and clear at all distances from the pinhole. The smaller the hole, the sharper the image, but the more exposure required. Also, in order to produce a reasonably clear image, the ratio of the pinhole, or aperture, size to the distance between it and the screen should be 1/100 or less. The shutter of a pinhole camera is usually manually operated because of the lengthy times, and consists of a flap of some light-proof material to cover and uncover the pinhole. Typical exposure times range from 5 seconds to hours and sometimes days. http://en.wikipedia.org/wiki/Pinhole_camera Aug 14 08, 6:59 AM
