What is photography

Photography (from the United Kingdom: photography, which comes from the word "Greece photos": light and "Grafo": Painting/writing) is the process of painting/writing using the media light. As a general term, photography means the process or method to produce a picture or photo of an object by recording the reflected light on the object on light sensitive media. The most popular tool for capturing this light is the camera. Without light, there are no photos that can be made.

Principle photography is the focus of the light with the help of refraction so that it is capable of burning the medium light catchers. The medium that has been burned with the right light luminitas size will result in a shadow is identical to the light that enters the medium refraction (lens).

To generate the right light intensity to generate an image, use the help of measuring instrument in the form of a lightmeter. After obtaining the proper lighting, size of a photographer can set the light intensity by changing the combination ASA/ISO (ISO Speed), the diaphragm Aperture, and shutter speed (speed). A combination of ISO, Diaphragm & Speed is referred to as exposure (exposure).

In the era of digital photography in which the film is not used, then the speed of the film originally used developed into Digital ISO.

The current photography has evolved into a lifestyle, this started since the advent of the digital era and the rise of social media.
