Small folk prescription for quick introduction to photography _ a little abnormal but very useful

A little abnormal, but I can get started quickly. Photography is a small remedy!

Factors affecting depth of field

1. Aperture:

You can adjust the depth of field range by adjusting the aperture size;

The larger the aperture, the shallower the depth of field and the blurred background;

The smaller the aperture, the deeper the depth of field and the clearer the background;

Large aperture: shooting people and still life; Small aperture: landscape, architecture.

2. Shooting distance:

The shooting distance will directly affect the depth of field;

The closer the shooting distance, the shallower the depth of field and the more blurred the background;

The farther the shooting distance, the deeper the depth of field and the clearer the background.

3. Focal length:

The longer the focal length, the larger the subject, which means that the shooting distance is close, the scene is deep and the background is blurred.

The shorter the focal length, the smaller the subject, which means that the shooting distance becomes farther, the depth of field becomes deeper and the background becomes clearer.

Focus mode of camera

1. Single autofocus:

After half pressing the shutter, you hear a beep, which means the focus is complete. Press the shutter to finish shooting. Generally suitable for shooting still life, such as commodity shooting, flower shooting, portrait posing and so on. The accuracy is very high.

2. Intelligent autofocus:

Is the camera's autofocus. Choosing single focus or continuous focus according to whether the subject is moving sometimes makes mistakes and the accuracy is not high.

3. Manual focusing:

This is the most accurate focusing method. When autofocus fails, such as shooting too close or being blocked by objects, it needs to be adjusted manually, and some subjects need to pay attention to details, such as macro shooting, which needs manual focusing.

4. Servo autofocus:

Servo focusing is also called continuous focusing. When shooting a moving subject, keep the shutter half pressed, which can keep the focus until the end of shooting. It is suitable for shooting moving subjects, such as sports and animals.

Photometric mode of camera

1. Evaluation photometry:

Evaluation photometry is an average measurement of light in the picture, which is not suitable for scenes with too large light ratio and will cause deviation of measurement results.

2. Spot metering:

Spot metering is to partial metering 3% of the screen area, which can ensure the accurate exposure when shooting small objects.

3. Central key measurement:

Central focus photometry is to measure the area 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.

4. Partial measurement:

10%~ 15% photo photometry is suitable for the situation that the subject is small and the brightness is obviously different from the environment.

Synthetic method

Common composition methods in shooting:

1. Guide line composition: use guide lines to attract attention to the subject;

2. Frame composition: Frame the racket body with the help of "frame" to better stand out;

3. Blank composition: leave a large area of the picture blank to simplify the picture elements;

4. Central composition: putting the subject in the center of the picture is the most commonly used one, which may not be very effective, but it will not make too many mistakes;

5. Triangular composition: divide the picture into nine points of nine squares, and put the main body on a straight line or intersection point to make the picture more vivid and not monotonous;

6. Symmetrical composition: the picture is symmetrical left and right or up and down, giving people a sense of calmness.

Types of lamps

Different kinds of light:

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

2. According to the soft and hard light, it can be divided into hard light and soft light.

3. According to the light source, it can be divided into natural light, ambient light and artificial light;

Natural light refers to the light that the sun shines on the earth as a light source;

Artificial light refers to the light produced by artificial instruments and equipment;

Ambient light includes natural light and artificial light.

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

Warm light refers to light with a color temperature below 3300K;

Cold light refers to light with a color temperature above 3300K K k.

5. According to the intensity of light, it can be divided into: strong light and weak light;

Strong light refers to the light with particularly hard light, such as the noon sun;

Weak light refers to light with softer light.
