Commonly used exposure values ??1. Starry sky with shutter priority: F1.4~5.6, portrait capture: F5.6~11 Night portrait: F2.8~5.6, close-up of flowers and grass: F1.2~4 Static portrait: F1.2~4

, Landscape photos: F8~11 Food/still life: F8~11, Fireworks/Star trails: F11~202, Daily shooting with aperture priority: 1/80s~1/200s, Fireworks shooting: 3~5s (preferably with a tripod)

, Capture people: greater than 1/125s, Capture athletes: greater than 1/1000s? Capture cars: greater than 1/2000s, Capture babies/pets: greater than 1/200s3, Fireworks in M ??mode: ISO 400F81~4s Lightning: ISO 200F8B door full moon

: ISO 200F5.6 (Sunny) 1/500s NO Galaxy: ISO 3200-6400F2.830s Metering Metering is to measure the brightness of the picture and provide exposure parameters.

There are three main metering modes: evaluative metering, center-weighted metering and spot metering.

1. Evaluative metering Evaluative metering is the most intelligent, measuring the average light in the picture.

However, it is not suitable for use in scenes with too large light ratio, and the measurement results will be biased, such as when there are large areas of bright or dark colors.

2. Center-weighted metering. Center-weighted metering is the most commonly used. It measures about 1/3 of the area in the center of the screen. When shooting, the subject is generally placed in the center. This can ensure that the subject is exposed correctly and avoid areas outside the center.

Area affects exposure results.

3. Spot metering. Spot metering is the most accurate. It measures 3% of the area of ??the screen. When the subject is not in the center, meter it directly at the subject to ensure the accuracy of the subject's exposure. It is the most accurate way. Combined with point

The measurement linkage function is the most perfect shooting method. Otherwise, you can only meter the exposure, lock the exposure, and then compose and focus the shot.

Focus 1. Single-shot autofocus is generally represented by AF-S. After half-pressing the shutter, you hear a "beep" sound, indicating that the focus is completed. Just press the shutter to shoot. It is generally suitable for shooting still life, such as product shooting, flower and grass shooting, and posed shooting.

Portraits etc.

2. Intelligent autofocus is the automatic focus of the camera, represented by AF-A. Depending on whether the subject is moving, you can choose single focus or continuous focus, but sometimes errors will occur.

3. Continuous (servo) autofocus Servo focus, also called continuous focus, is represented by AF-C.

When shooting moving subjects, keep pressing the shutter button halfway, and you can continue to focus until the end of shooting without pressing the shutter button halfway again. It is suitable for shooting moving subjects, such as sports, animals, etc.

4. Manual focus is represented by MF, which is the most accurate focusing method.

When the autofocus fails, such as when the shooting distance is too close or there is an object blocking it, manual focus adjustment is required.

There are also shooting subjects that require attention to details, such as macro shots, where manual focus is required.
