There are people who don't know this folk prescription! Photography has changed since I learned it.

1. hole

The larger the aperture value, the less light entering, the smaller the aperture and the smaller the blur.

The smaller the aperture value, the more incoming light, the larger the aperture and the greater the blur.

2. Shutter

The smaller the value, the faster the shutter speed, the less light entering and the darker the photo.

The larger the value, the slower the shutter speed, the more light entering and the brighter the photo.

3. Sensitivity

The larger the ISO value, the more light enters, the brighter the photo and the worse the image quality.

The smaller the ISO value, the less light enters, the darker the photo, and the better the image quality.

Commonly used exposure value

1. When the shutter takes precedence.

Daily shooting: 180s~ 1/200s, car snapshot:1/200s or more.

Baby/pet pat: V200s or above, idolized/athlete:11000s or above?

Shooting fireworks: 3s~5s (with tripod), arresting people:1125s or more.

Orbit: > 2 hours (tripod), light drawing: 15s~30s.

2. When the pore size is preferred

Static picture: F 1.2~4, close-up of flowers: F 1.2~4, night portrait: F2.8~5.6.

Catch people: F5.6~F 1 1, food/still life: F8~ 1 1, fireworks/light painting/star track: f1-20.

Starry sky: F 1.4~5.6, landscape photo: FB~ 1 1.

3. Manual M gear

Take photos, shutter1125s, aperture F 2.8, and sensitivity ISO 100. (Sunny) Shooting scenery, shutter1125s, aperture 4, sensitivity ISO 100. (Sunny) Shooting night scene, shutter115s, aperture 1.8, sensitivity ISO 200. Shooting action, shutter 1/500s, aperture 2.4, sensitivity ISO 100.

Focus mode

1. Single autofocus

Auto-focus operation A single auto-focus is generally represented by AF-S, and a "click" sound is heard after half pressing the shutter, indicating that the focus is completed. You can shoot by pressing the shutter, which is generally suitable for shooting still life. For example, commodity shooting, flower shooting, posing for people and so on.

2. Intelligent autofocus

Is the camera autofocus, represented by AF-A, according to whether the subject is moving or not, it is sometimes wrong to choose single focus or continuous focus.

Manual focus

Manual focusing is expressed by MF, which is the most accurate focusing method. When autofocus fails, for example, the shooting distance is too close and there is an object blocking, it is necessary to manually focus to adjust. There are also details that the subject needs to pay attention to, such as macro shooting, which needs to be manually focused.

4. Servo (continuous) autofocus

Servo focusing, also known as continuous focusing, is expressed by AF-C. When shooting a moving subject, you can continue focusing until the shooting is over without pressing the shutter again, which is suitable for shooting moving subjects, such as sports and animals.

Photometric determination

1. Evaluation photometry is the smartest.

Evaluation photometry is the average measurement of light in the picture, and it is the most intelligent. However, it is not suitable for scenes with large illumination ratio, which will lead to deviation of measurement results, such as large areas of light or dark.

2. Spot metering is the most accurate.

Spot metering measures 3% of the screen area. When the subject is not in the center, it is the most accurate method to directly measure the light at the subject to ensure the accuracy of the exposure of the subject. Combining the point measurement linkage function is the most perfect shooting method, otherwise it will only be locked and refocused after metering.

3. Central dimming is the most commonly used.

Center-focused photometry is to measure the face position around 1/3 in the center of the picture. When shooting, the subject is usually placed in the center to ensure the correct exposure of the subject. At the same time, the influence of the area outside the rabbit center on the exposure results can be avoided.

White balance (K) controls the color of the picture and affects the color temperature of the photo.

How to adjust the value of white balance?

When the value of K >: 5000K, the color of the scene is reddish, which belongs to warm tone and has a warm and steady atmosphere effect; Suitable for shooting indoor effect portraits.

When the k value is 4000-5000k, it belongs to the effect of normal middle tone and white tone, which is really an environmental effect; Effective shooting location with good light, portrait/style is ok.

When the value of k is
