Introduction to Cameras

When the composition is judged to be 'just right', then the shutter is released by pressing a button. Light passes through the lens and the aperture and is focused onto the sensor. The shutter is closed at a point when enough light has reached the sensor to form an image. . . . (to read the remainder of this article, please log in below.)
