Camera m file operation guide

M-file Adjustment Ideas —— Introduction to Photography Teaching (Required for Beginners)

What is M-file?

The M range of the camera is fully manual, and you can freely adjust every parameter on the camera, such as aperture, shutter and sensitivity. It may be a bit difficult for beginners, but it is very controllable! We can shoot our favorite theme according to different parameters. If you want to play with the camera, let's see how to use the M file ~ Method 1: Adjust the turntable at the top of the camera; Method 2: Adjust the camera parameter interface.

Three Elements Exposed by Moving Files

There are three main parameters to pay attention to in M-file: aperture, shutter and sensitivity (also known as exposure three elements), and the combination of these three factors controls the exposure size.

1. aperture. The larger the aperture data is, the less light enters, and the smaller the aperture is, the smaller the blur is. The smaller the aperture data, the more incoming light, the larger the aperture and the greater the blur.

2. shutter. The larger the shutter data, the more incoming light, the smaller the aperture and the slower the speed. The smaller the shutter data, the less light entering, the larger the aperture and the faster the speed.

3. sensitive. The larger the ISO data, the more light enters, the brighter the photo and the rougher the image quality. The smaller the ISO data, the less light, the darker the photo and the finer the picture quality.

How to adjust the aperture?

If you want to take a blur effect, you must first determine the aperture value. Aperture is a device to control the amount of light entering the lens, which is represented by F. Here, we should know a definition: the greater the value of F, the smaller the aperture, the less the amount of light entering, and the darker the photo. The smaller the f value, the larger the aperture, the more light entering and the brighter the photo. Large aperture depth of field is small, and small aperture depth of field is large.

It should be noted that! ! !

The size of the aperture will also affect the depth of field of the photo; The larger the aperture, the smaller the depth of field; The smaller the aperture, the greater the depth of field. Large aperture is often used when taking portraits, and small aperture is often used when taking scenery.

How to adjust the shutter?

If you want to capture an action or take a slow-motion photo, you must first determine the shutter. Shutter is a device used to control the amount of light, so as to control the amount of light. Here, everyone must know a definition: the larger the shutter value, the slower the speed and the brighter the photo. The smaller the shutter value, the faster the speed, the less light entering and the darker the photo. The high-speed shutter will freeze, and the vulgar shutter will have a trajectory effect.

It should be noted that! ! !

Except when shooting the slow door, it is suggested that the daily photography should not be lower than1125s, otherwise the photo will be blurred due to hand shaking, but if the aperture has been opened to the maximum when the picture is still dark, then the ISO needs to be adjusted.

How to adjust the sensitivity?

Before adjusting the parameters, we need to adjust the ISO according to the lighting environment. Everyone here must know a definition: the higher the sensitivity, the more sensitive the sensor is to light, the lower the sensitivity, the less sensitive the sensor is to light, and the smaller the exposure. Low-sensitivity images have good quality, while high-sensitivity images have poor quality (photos will have noise).

It should be noted that! ! !

The greater the sensitivity, the better. Too high sensitivity will affect the image quality. For daily shooting, it is recommended to adjust the sensitivity to 100.
