Camera m module

First, know the M file (what is the M file? )

M gear is full manual mode. In this mode, each parameter is set by ourselves. M file can freely choose the aperture and speed according to the scene and shooting needs, and shoot the desired effect. Including: manual adjustment of aperture, manual adjustment of speed, manual focusing and so on.

Second, the camera adjustment mode dial:

M full manual mode;

A+ full automatic mode;

P program automatic mode;

AV aperture priority mode;

Television shutter priority mode;

SCN scene priority mode;

M speed camera interface.

Exposure is what we often say about the brightness of photos. The correct exposure is mainly to adjust the shutter, aperture and sensitivity according to the shooting environment, so that the photos can reach the normal exposure state.

Third, M file: three elements of exposure (the three giants that affect the normal brightness of photos)

Three factors that affect exposure:

Aperture: There is a light hole on the lens, the size of which is controlled by the surrounding metal sheet, thus controlling the light input of the camera.

Shutter: When we take pictures, we usually refer to the shutter speed or shutter time, which is an important factor in determining the exposure of photos.

Sensitivity: the abbreviation of sensitivity is ISO, which refers to the sensitivity of photosensitive elements to light. Sensitivity is expressed by the numbers in the camera.

Fourth, the three elements of exposure: aperture (what is aperture? )

Aperture: The lens consists of a set of blades, and a light hole will be formed in the middle of the blades. The light hole can be adjusted up and down, and light enters through the light hole.

Aperture is generally represented by "F+ number"

The smaller the number after f, the larger the aperture, and the more light per unit time; The larger the number after f, the smaller the aperture, and the less the amount of light per unit time:

The larger the aperture, the more light enters, the brighter the picture, and the more obvious the background blur; The smaller the aperture, the less light enters, the darker the picture, and the less obvious the background blur.

Five, three elements of exposure: shutter (what is shutter? )

Shutter: the light enters another door of the camera, which is composed of a set of blades, similar to a shutter. Control the length of light to control the amount of light.

The unit of shutter time is seconds, which is expressed on the screen as 1/60,1125, etc. Take the shutter time of1125 as an example, that is to say, the shutter opens1125 seconds, which is very short. The shorter the shutter opening time, the less light enters the camera through the lens under the same aperture.

Other parameters being constant, the shorter the shutter time, the less light entering and the darker the picture; Other parameters being the same, the longer the shutter time, the more light enters and the brighter the picture.

Six, three elements of exposure: sensitivity (what is sensitivity? )

Sensitivity: The key symbol of sensitivity on the fuselage is ISO, which refers to the sensitivity of photosensitive elements to light.

The higher the sensitivity value, the higher the sensitivity and the more sensitive the camera is to light. The lower the sensitivity value, the lower the sensitivity, and the less sensitive the camera is to light.

The greater the ISO value, the higher the sensitivity, the more light entering and the brighter the photo. The smaller the ISO value, the lower the sensitivity, the less light entering and the darker the photo.

The larger the ISO value, the more noise and the rougher the picture. The smaller the ISO value, the less noise and the finer the picture.
