Dry goods attack the secret? I heard that there are people who can't use the M file?

Are all the friends who just started the camera eager to try M-file shooting, but they are worried that M-file is difficult to operate? If you can't use M file yet, come to Kangkang ~ We want to use M file flexibly. The first step is to understand the three elements of M file exposure-aperture, shutter and sensitivity ISO?

what is file m?

every parameter of the camera, including aperture, shutter, sensitivity, white balance and so on, can be freely adjusted in M file, which is flexible and can be adjusted to get the desired effect.

adjustment method 1: rotate the turntable at the top of the camera.

adjustment method 2: camera parameter interface adjustment.

adjust the aperture

if you want to shoot the blur effect, you should first determine the aperture, which is a device to control the amount of light in the lens, and is represented by F ..

the smaller the aperture f value, the more light enters, and the larger the aperture, the better the blur effect. The larger the aperture f value, the less the light enters, and the smaller the aperture, the worse the blur effect.

aperture: the smaller the aperture value, the less the clear range of the picture and the more obvious the blur of the picture background. The larger the aperture value, the more clear the picture range, and the less obvious the background blur.

adjust the shutter

if you want to capture motion or take slow-motion photography, you must first make sure that the shutter is the device to control the exposure time in the camera, which is denoted by S.

the shutter should not be lower than 1/125S when shooting the slow door, otherwise the picture will be blurred due to hand shaking.

if the shutter is at 1/125, the picture is still dark and the aperture has been opened to the maximum, it is necessary to improve the ISO.

the larger the shutter value, the more light enters and the slower the shutter speed. The smaller the shutter value, the less light enters and the faster the shutter speed will be.

the high-speed shutter will freeze, and the low-speed shutter will have a track.

shutter: high-speed shutter can better freeze some dynamic scenes; The slow shutter can record the track and get more exposure.

adjust the sensitivity

before adjustment, we need to adjust the ISO sensitivity according to the lighting environment.

low-sensitivity image quality is better, while high-sensitivity image quality is poor (photos will be noisy).

the higher the sensitivity, the brighter the photo and the worse the picture quality. The lower the sensitivity. The photos are darker and the picture quality will be better.

sensitivity ISO: the picture can be brighter by increasing the sensitivity.

exposure value is commonly used

1. When the aperture is given priority

Fireworks shooting: 3~5s (with tripod), daily shooting: 1/8s~1/2s, athletes shooting: more than 1/1/2s, people capturing: more than 1/125th s, babies/pets shooting: more than 1/2s.

2. when the shutter is in priority

starry sky: F1.4~5.6, portrait at night: F2.8~5.6, static figure: F1.2~4, food/still life: F8~11, snapshot of people: F5.6~11, close-up of flowers and plants: F1.2~4, and landscape photos:.

3.M

Fireworks: ISO4 F8 1~4s, lightning: ISO2 F8 B door, full moon: ISO2 F5.6 (sunny day) 1/5s, Galaxy: IS32-64F2.83s.

but friends should pay attention! The higher the sensitivity, the more noise there is in the picture, so we should try to reduce the sensitivity and ensure the texture of the picture? Is it easy to learn M-files based on the theory of three elements of exposure? ? Pick up your camera and practice ~
