What is it Photography?

Photography is comes from two words, photo means light and graph means writing or painting. In the visual arts, photography is the process of painting or writing by using the lighting. As a general term, photograph is process or method to produce picture or image of an object by recording the reflections of the object on a light-sensitive media. The most popular tool for capturing light is camera, so it can be concluded that there is no light, there are no image that can be made. The principle of photograph is to help focus light by refraction, so be able to burn medium light catcher. Medium that had been burned to the iluminitas of the right light will produce shadow identic with light entering the medium refraction (lens).

To produce the appropriate light intensity to produce image, used aid in the form of light meter gauge. After getting the size right lighting. A phorographer can adjust the light intensity by changing the combination of ISO or ASA (ISO Speed), diaphragm, and shutter speed (Speed). Combination of ISO, diaphragm, beyond the speed as exposure.

Annotation

light meter is a device for measuring light intensity test or measure the amount of light coming through the light measuring test equipment

Iso speed is the number used to represent the international Standards Organization to rate the sensitivity of the film and the amount of light required to capture photo camera

diaphragm is a component of the function of the lens which controls the intensity of light coming into the camera

means closing the shutter speed (to shoot) when we press the button to take pictures, there was the formation of the lens so that light enters and the film.
