On the face of it this is a little cumbersome - but it has a couple of advantages over a fixed screen. Lengthening development time lightens the resulting images, which otherwise would appear too dark. Filters added to the front of a camera lens change the quantity or quality of the light that reaches the film.
| Digital Camera Back info: Most types of film produce a negative image, from which a positive final copy can be printed on sensitized paper. If the lighting is harsh, resulting in high contrast between light and dark areas, a sophisticated photographer might overexpose the negative and then shorten its development time to subdue the harsh light. These categories refer to the means by which output is sent to the printer rather than to any mechanical distinctions. This measures the exposure at a small, precise portion in the centre of the lens, allowing the user to ensure perfect exposure on a particular section of the scene.
