What is photography? As a beginner, we try to find out this answer from many books and blogs. In general, photography is an activity of exposure for a film or a digital sensor in a camera.

The process of an exposure can be, in general, divided into the following.

1. the capture of the reflected light,
2. the control of the amount and intensity of the light rays to enter the camera and fall onto the digital sensor,
3. the transformation of light rays into digital image data.
4. and, the digital image data will then be stored in a memory card.
