Basic knowledge of photography-cognitive interface 1. Exposure mode:

A+ full automatic mode: All parameters are automatically set by the camera and cannot be adjusted by itself.

P program self-mode: except shutter and aperture, other parameters can be adjusted by themselves.

AV aperture wired mode: In this mode, the parameters such as aperture and ISO can be adjusted by itself, and the shutter is automatically matched by the camera.

TV Shutter Priority Mode: In this mode, parameters such as shutter and S0 can be adjusted automatically, and the aperture is automatically matched by the camera.

M Full manual mode: In this mode, all parameters can be adjusted freely.

ACN scene automatic mode: people, scenery, sports and other modes. Automatic parameter setting, which can be understood as automatic mode, has special skills.

2. Shutter value:

The unit of shutter is seconds. Display 1/60,1125,1125, 1/2000, etc. On the screen.

Other parameters being the same, the longer the shutter time, the more light enters and the brighter the picture.

Other parameters being the same, the shorter the shutter time, the less light entering and the darker the picture.

3. Aperture value:

Aperture is generally represented by a+number.

The smaller the number after f, the larger the aperture, the more light per unit time, and the brighter the picture.

The larger the number after f, the smaller the aperture, the more light per unit time, and the darker the picture.

4. sensitivity ISO:

The key logo of photoreceptor is IS0, which refers to the sensitivity of photosensitive element to light. The higher the sensitivity value, the higher the sensitivity, the more sensitive the camera is to light and the brighter the picture. The higher the sensitivity, the more noise and the rougher the picture. The lower the sensitivity value, the lower the sensitivity, the less sensitive the camera is to light and the darker the picture. The lower the sensitivity, the less noise and the finer the picture.

5. Scale of exposure indicator:

You can see a scale-like icon on the screen, which is the camera's exposure indicator scale. When the middle arrow points to 0, it means that the exposure is normal. If the negative value on the left indicates underexposure, if the positive value on the right indicates too much noise.

6. Measurement mode:

1. Evaluation photometry

Two-point photometry

3. Partial measurement

4. Center key average photometry

7. Auto focus function:

AF manual focusing: press the shutter to automatically focus the camera. When you press the shutter for the first time, you will hear a "drip" to indicate that the focus is complete.

There are three modes for autofocus mode:

1. Single autofocus is suitable for shooting still objects.

2, artificial intelligence focusing-suitable for shooting moving objects.

3. Artificial intelligence autofocus can automatically switch between single focus mode and artificial intelligence servo focus mode, so it is often used to shoot unpredictable objects.

MF Manual Focus: You need to turn the focus ring to complete the focus.

8. Auto focus point selection:

1. Single point autofocus

2. Area autofocus

3. Large area autofocus

4.45 point autofocus

9. Photo style:

The photo style is mainly set in four aspects: sharpness, contrast, saturation and tone. Our common styles are: automatic, standard, portrait, landscape, neutral, reliable and monochrome, which can be adjusted according to high demand.

10. White balance:

The main function of white balance is to restore the original color of the object, which is represented by K on the camera. The greater the k value, the yellower the photo and the warmer the tone. The smaller the k value, the bluer the photo and the colder the tone.

1 1. White balance correction:

Manually adjust the white balance parameters to correct the color of the picture.

12. White balance around exposure:

A shooting method in which the camera automatically carries out tone compensation from the red system to the blue system or from the green system to the magenta system based on the reference white balance.

13. Photo format:

Commonly used photo formats are: JPEG format and RAW format-

JPEG is a popular image storage format, which reduces the storage size by compressing data. This format is usually enough for shooting.

RAW: This is an original image file format. It is not compressed, and all the data is preserved. The data will be relatively large, and general commercial photographers will use RAW format.

14. Automatic brightness optimization:

During the imaging process, the appropriate brightness and contrast can be automatically adjusted according to the shooting results. It can analyze the brightness of the subject and adjust the dark parts in the image to natural brightness.

15.WIFI function:

As long as the camera control APP software is installed on the mobile phone, you can establish a communication link with the camera without the help of other networks. After connecting, you can save the photos you took on your mobile phone! ! !
