How to use the M file of SLR correctly?

Full manual shooting is not only to set the shooting mode to M for shooting or manual mode, but also to set all the settings related to manual mode. First, set the shooting mode to M position, then set the A/M selector switch on the lens to M, use manual focusing, and then select the focusing mode in the camera as MF, that is, manual focusing, so as to complete all the settings of manual focusing and carry out real manual focusing.

Manual focusing requires the photographer to know enough about the aperture and shutter, to accurately judge what kind of aperture and shutter should be set to make the photo accurately exposed, and to accurately change and adjust the aperture and shutter at any time according to the changes of environment and light. For example, it takes 1 1 aperture1125 a second to take a portrait in the sun. Then, when clouds come to block the sun or people move to the shadow to shoot, then the aperture should be adjusted to 8, or the speed should be adjusted to 1/60 seconds to ensure the accuracy of exposure. ?

When you want to take pictures manually with the camera, you should use M file, which is very suitable for taking pictures of landscapes, portraits in sheds and so on. Unless you don't take a snapshot. Because it can change the corresponding value completely according to the photographer's wishes.

M file refers to a file on the full manual camera function dial. And m is called full manual function. Using 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.
