What is the camera M file and how to use it?

Camera M file is a file on the full manual camera function dial, and the usage method is as follows:

We need to determine an ISO value according to the scene environment, and shoot under the condition of sufficient light. It is suggested that ISO should be controlled at 100. The lower the sensitivity, the purer the picture and the richer the details. Therefore, even if it is dark shooting, ISO recommends not to exceed 6400. If the picture is still dark, you can only use the fill light to assist shooting.

If you want to take a portrait with a blurred background, you can turn the aperture to the maximum and get a beautiful background blur. If you want to shoot an environment, portrait or landscape with a clear background, you can use a small aperture above F8, and the background will hardly have obvious blur effect. If you want to record the motion trajectory of an object, it is recommended to use a shutter below110, such as taking creative photos such as water flow, wire drawing and light track.

Matters needing attention in the use of camera M file

1. When using M file, exposure compensation such as "white plus black minus" no longer works, but only works in automatic modes such as A, S or P. ..

2. It is recommended to use spot metering to measure light, especially for cameras with linkage function. Spot metering is aimed at a certain "point", which is more accurate.

3. In portrait shooting, when shooting with M-files, it is suggested to aim the metering point at the subject, no matter how dark the background how bright is, the metering of the subject shall prevail. This is the first condition to ensure the normal exposure of characters, unless you want to deliberately pursue a certain atmosphere or effect.

4. If the light is too dim when using M-range to adjust parameters, it is not recommended to slow down the shutter to get more light, because it is easy to be empty when the shutter is slow. The ideal adjustment sequence is to increase the aperture or ISO. Neither of these methods can meet the exposure requirements, so you can make up the extra light and finally lower the shutter.
