What are the camera shooting modes M, S, A and P?

1, camera shooting mode M file is manual exposure mode. According to the needs of shooting, the aperture, shutter and sensitivity are all set by ourselves, and the sensitivity is generally lowered, and the exposure effect is basically expressed by aperture and shutter. Suitable for shooting in extreme environments, such as backlight, special effects and so on.

2, the camera shooting mode S file is the shutter prerequisite mode. Shutter speed is preferred, aperture and sensitivity are automatic. Even if the shutter speed changes, the final exposure remains the same. Shutters must be suitable for expressing motion and shooting moving objects.

3, camera shooting mode A file is the aperture prerequisite mode. The aperture is set first, and the shutter speed and sensitivity are automatic. You can choose the aperture according to the depth of field required by the picture, and the shutter speed and sensitivity will automatically keep the final exposure unchanged.

4, camera shooting mode P file is program automatic exposure mode. Adjust the brightness of the picture through exposure compensation. If it is brighter, adjust it to the left, and if it is darker, adjust it to the right. You can set the sensitivity and adjust the brightness of the picture, and the flash will not pop up automatically.

Extended data:

The advantage of P file is that you don't have to consider the matching of aperture and shutter. As long as you set other parameters, the rest will be handled automatically by SLR. The disadvantage is that the iso is not well adjusted, which easily leads to inaccurate photo exposure; When the aperture of the camera lens is small, the shutter will slow down and the picture will be blurred.

The advantage of the file is that it is suitable for shooting still life, and it can control the depth of field and strengthen the visual center. The disadvantage is that if the lens aperture is not large enough, it needs to be photographed by hand in weak light, which is easy to blur.
