How does Nikon D300S adjust the shooting mode?

Manual mode, also known as M-file, is an exposure mode in which the photographer completely controls the aperture size and shutter speed. That is to say, aperture, shutter, sensitivity and so on. All need to be adjusted manually, so as to control the picture.

With M-file shooting, you can freely choose the aperture and speed according to the needs of the scene and shooting, and shoot the desired effect. However, shooting in the m range is not simply to adjust the camera to the m position, but to use full manual, including: manually adjusting the aperture, manually adjusting the speed, manually focusing and so on.

2. Aperture priority mode, that is, AV file.

Different from manual mode, aperture priority mode can be said to be the most used mode in all shooting modes, which can basically meet most shooting needs. In aperture priority mode, the camera will automatically give the corresponding shutter speed as long as the aperture size is properly adjusted.

AV file has two main advantages: first, adjusting the aperture size can directly control the depth of field, and second, you don't have to worry about the shutter speed. So in most cases, you can use aperture priority mode to shoot, so you don't have to worry about the shutter speed, but in some cases, you need to care about the shutter speed.

3. Shutter priority mode, that is, TV files.

Shutter priority is to get the aperture value through camera metering when the shutter is defined manually. For TV files, just adjust the shutter speed, and then the camera will give an aperture value according to the set shutter speed. This mode is just the opposite of aperture priority mode.

Shutter priority mode is most suitable for shooting moving things, because it can not only clearly shoot the moment of object movement, but also shoot the trajectory of object movement.

4, program exposure, namely P file

Simply put, the P file of SLR camera is semi-automatic mode, and the P file is program automatic exposure mode. In this mode, everything can be adjusted except the parameters of aperture and shutter. In this mode, the camera can set the shutter speed and aperture size according to the internal program of the camera to obtain the correct exposure result.
