I won't allow it, and I won't use M file

M file (full manual mode). In this mode, the parameters such as aperture, shutter and sensitivity are all adjusted by ourselves. Various parameter values fully serve our own consciousness and needs. 1. Turn the top of the camera to the M position. 2. Adjust the shutter, aperture, sensitivity (from left to right) and other parameters.

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 denoted by F ..

here, you must know a definition: the smaller the aperture value, the more light enters, and the larger the aperture, the better the blur effect. The larger the aperture value, the less light enters, and the smaller the aperture, the worse the blur effect.

three elements of m-file exposure

aperture (f): a device to control the amount of light entering. The smaller the value, the brighter the picture. Shutter (1/x): Time to receive light. The slower the shutter, the brighter the picture. Sensitivity (IS port): the sensitivity of the photosensitive device to light. The larger the value, the brighter the picture.

adjust the shutter

if you want to capture the motion or take slow-motion photography, you should first determine the shutter, which is the device to control the exposure time in the camera, which is denoted by S. Here, you must know a definition: the larger the shutter value, the more light will enter, the slower the shutter speed will be, and the smaller the shutter value, the less light will enter and the faster the shutter speed will be.

The shutter should not be lower than 1/125S except when shooting the slow door, otherwise the picture will be blurred due to hand shaking. If it is found that the shutter is at 1/125 and the picture is still dark and the aperture has been opened to the maximum, it is necessary to increase the lead S.

adjust the sensitivity

before adjustment, we need to adjust the 1SO sensitivity according to the lighting environment. Here, we must have a definition: the higher the sensitivity, the brighter the photo will be, while the lower the sensitivity, the darker the photo will be. At the same time, the photo quality will be better at low sensitivity, and the high sensitivity will be poor (the photo will have noise).

Summary of scene parameters of ISO sensitivity

Then, according to the shooting environment and light, decide whether to adjust the aperture or the shutter first. If you want to shoot blur effect, set the aperture first, and then adjust the shutter according to the brightness of the picture ~ I usually open it to the maximum aperture of 1.8, and my friends can adjust the aperture value according to their own lenses ~

When shooting, I suggest choosing weather with sufficient light, and 1S can be controlled at around 1 in good days.

Here, everyone should pay attention to not exceeding 64 when shooting 1S at night. High sensitivity will cause a lot of noise in photos. If it is still dark, you can only use the fill light to fill the light, which can ensure both the painting and the brightness of the picture.

Common shutter speed settings

Daily shooting: 1/6s~l/25s, fireworks shooting: 3s~5s (tripod), baby/pet shooting: over 1/4s, starry sky shooting: 15s~25s tripod, people capturing: over 1/4s, and light painting: 8s ~ 3s. .5 hours (tripod), capturing cars: more than 1/5 s.

note: if the shutter speed is lower than 1/8s, it is recommended to take it. The aperture f value is usually set. Group photo: F8-16, scenery photo: F8-18, night portrait: F1.-4, food/still life: F1.8-11, starry sky: F1.2-4-5.6, and figure capture: F.
