First say a picture of the main technical decision factors: 1. light. No light can not shoot, special equipment and of course at night can also shoot, such as infrared photography, most people do not encounter these issues. Remember, the first element is light photo effect. Light good pictures, noon evening than in the daytime than indoor, outdoor strong. 2. shutter. Said shutter speed, speed. It is a concept of time, time. For example, 1/125, 1/8. This action is to open the camera into the light of the door is the door open, 1/125 seconds 1/125 seconds and shut the door, than the general speed of the much faster, as fast, so called shutter. Usually we use S shutter speed, second prefix. The shutter things are usually in the body, a lens shutter professional equipment, installed in the lens by name. 3. aperture. Is the light inlet hole. It inside the camera, can be opened, can open a small. F + Digital generally used, said aperture size, such as F8, F5.6, F22. It is that the larger the number, the smaller the hole. 4. sensitivity. It refers to the film speed, some sensitive, fast. Some late, slow. ISO. For example, ISO50, ISO800, the smaller the value the more slowly. The camera to take a photo to a light. The shutter, the aperture and the sensitivity of the combination reached. Can be understood as the door opened much open long, this will determine how much light came in, this process is called exposure. Of course, according to the light in the film or digital camera CCD (it is equivalent to the film), so one of the film is sensitive factors. The shutter aperture sensitivity = + + light. For example: (shutter) S1/125+ (aperture) F8 (ISO) ISO100= accurate light.
