The camera looks at it with a treasure that eats ash.

A very abnormal skill, but it can make your photography soar, absolutely yyds! !

First of all, the three elements of exposure

1, aperture f:

The larger the F value, the smaller the aperture, the less the amount of light entering, and the blurring effect is weak; The smaller the F value, the larger the aperture, the more light entering and the stronger the blur effect.

2. shutter s:

The larger the shutter value, the slower the speed, the more light entering and the slower the door effect; The smaller the shutter value, the faster the speed and the less the amount of light, which is suitable for snapshot.

3. Sensitivity ISO:

The larger the ISO value, the more light enters, the brighter the photo and the more noise. The smaller the ISO value, the less light entering, the darker the photo and the less noise.

Second, the exposure numerical reference

1, AV aperture priority mode:

Shooting scenery: F8-F 1 1 (small aperture);

Shooting portraits: the maximum aperture below F2.8 (background blur highlights the subject);

Shooting still life: the maximum aperture below F2;

Macro shooting: F8-f11;

Shooting Star Man/Slow Gate: F 1 1-F20.

2. TV shutter priority mode:

Normal portrait posing:1/more than 80 seconds (more than 200 is recommended);

Dynamic snapshot:1/more than 500 seconds;

Running/flying birds/waterfalls:11000 seconds ~ 1/2000 seconds;

Slow door/taillight drawing/light drawing: 1/30~ 1/4 seconds.

3.M-gear pure manual mode:

Outdoor portrait: 1/200 seconds, ISO 100, F 12-4 (sunny day);

Indoor portrait: 1/80 seconds, ISO 1500 or so, lower than F28.

Shooting the full moon: 1/500 seconds, F8 ISO200；;

Shooting the Milky Way: 30 seconds, ISO3200-6400, F2.8

Three, focusing, metering, white balance

① Focus mode

The focusing mode of the camera is mainly divided into:

1. Single autofocus (AF-S);

2. Servo autofocus (AF-C);

3 intelligent autofocus (AF-A).

② metering mode

The metering modes of the camera are mainly divided into:

1, evaluating photometry;

2. Spot metering;

3. Central key measurement.

③ White balance

White balance function of camera:

Correct the color temperature and restore the color of the object itself;

With the increase of K value, the photos are warmer (yellowish);

Turn down the k value, and the photo will be cool (blue).

Fourth, photographic light.

Types of lamps

① According to light source: it is divided into natural light, artificial light and ambient light.

1, natural light: the light source of natural light generally refers to all light sources from nature, such as sunlight and moonlight. Natural light shooting is the most commonly used in daily life.

2. Ambient light: Ambient light includes natural light, such as sunny day, cloudy day and sunset, but it also includes artificial light. For example, the ambient light generated by illuminating a room belongs to ambient light.

3. Artificial light: light produced by artificially manufactured equipment or instruments, such as incandescent lamps.

② According to the color of light, it can be divided into warm light and cold light.

③ According to the quality of light, it can be divided into strong light, soft light, strong light and weak light.

④ According to the light direction, it can be divided into front light, back light, top light and side light.
