In about 1950, the concept of en: exposure values developed in Germany to simplify measurement of light falling onto the focal plane by removing the lens parameters to define the absolute values into relative exposure.
To help photographers get the most appropriate settings for Exposure, used lightmeter. Lightmeter, which usually already exist in the camera, will measure the intensity of light entering the camera. In order to get normal Exposure.
Exposure is a term in photography that refers to the amount of light that falls into the medium (film or image sensor) in the process of capturing images.
There are also some things that can affect the level of exposure that is the type and intensity of the light source, the response object with ambient light, camera distance with the object rule, shutter speed, aperture, iso / asa film, and of course filters.

Exposure levels will affect the overall picture brightness. In addition, the response of each object in a photographic work will be different, so that with proper processing photographers can adjust the resulting emphasis.
There are two types of exposure is not normal that is often encountered in the work of photography, namely over-exposure and under exposure.
Over-exposure is a state photo dipajan longer than instructed lightmeter or subject that captured more light than it is. While the exposure is under opposite circumstances.
There is no right or wrong size for the determination of Exposure. Depends entirely on the level of emphasis and the desired image photographer.
As we know that the outside light is passed by the lens toward the upper focal plane. In the process, light passes through the obstacles along the line of optical lenses and a portion of it will be muted (because they do not have the amplitude / intensity is quite significant), or reflected by the surface of each line of the lens to affect the color accuracy on the final image, effect flare or ghosting artifact / motion blur; as a result of the continuing nature of the lens, refract, absorb, reflect light.
This means that, although commercial lenses have ditera based on the standard CCI (Colour Contribution Index) established by the IOS (International Organization for Standardization), the use of glass is different for each lens and the type of coating used will affect the wide spectrum and intensity of light reaching the surface of the focal plane.
