1. Adjust to M file.

Turn the dial on the top of the camera and turn to M (full manual mode). In this mode, we can adjust all the parameters of the camera, freely adjust the aperture, shutter and sensitivity iso according to the scene and shooting requirements, and shoot the desired effect.

2. Adjust the exposure parameters

In M mode, the main parameters we adjust are the three parameters circled in the figure, namely aperture, shutter and sensitivity iso, which affect the "exposure of photos". When we adjust the parameters, we can observe the exposure index table in the picture to see if the photos are exposed normally. When the scale is to the left of "0", it means that the exposure is insufficient. When the scale is to the right of "0", it means overexposure.

3. How to adjust the aperture

What is an aperture? Aperture is a set of openable blades, which can control the opening and closing degree of the blades, and then affect the amount of light entering the camera. Generally, it is displayed as F+ number on the camera. The smaller the f value, the larger the aperture, the more light entering, the brighter the photo and the shallower the depth of field. The larger the F value, the smaller the aperture, the less light entering, the darker the photo and the deeper the depth of field.

Common aperture numerical reference: flower close-up: F 1.2-F4, group photo: F8-F 16, car snapshot: F5.6-f1,landscape shooting: F8-f1/kloc.

4. How to adjust the shutter

What is a shutter? Shutter is a device that controls the length of light entering the camera. 0 The larger the shutter s value, the more light enters and the slower the shutter speed. The slower the shutter, the smaller the shutter s value, the less light entering and the faster the shutter speed.

Commonly used shutter numerical reference: catching people: 1/ kloc-0/25s or more, shooting stars: 25s-30s, daily shooting: 1/60s- 1/250s, shooting fireworks: 3s-5s, shooting pets:/kloc-0.

5. How to adjust the sensitivity

What is sensitivity iso? Sensitivity is the sensitivity of the camera's photosensitive original, which is generally expressed by ISO. When taking pictures, you can give priority to the shutter and aperture, and then adjust the sensitivity. The smaller the ISO value, the less sensitive the sensor is to light and the darker the photo. The larger the ISO value, the more sensitive the sensor is to light and the brighter the photo is. The greater the sensitivity, the better. The higher the sensitivity, the more noise the photo produces, which affects the image quality.

Common sensitivity values: sunny day: 100, evening: 800, cloudy day/indoor: 400, night scene: 1600. Note: Even when shooting at night, ISO should not exceed 6400, otherwise there will be a lot of noise in the picture, which will affect the picture quality.
