What is the white balance of the camera and how to tune it

White balance is a proper noun for digital cameras, each digital camera has the ability to adjust white balance, the concept of white balance is the same as the concept of light film and daylight film in film, it is to get an accurate image of color in different color temperature environments, just like the color temperature under the noon sun is 5500K, and the fluorescent light is 3200K, the general tone can meet the general daily application on the automatic gear, if you find that the ** color cast shot by the automatic gear, you must use manual white balance settings, the general setting is divided into sunshine and cloudy days, backlight, sunrise and sunset, fluorescent light and flash, etc., each camera has a different way of adjusting, how to adjust the white balance, please refer to the manual.

Let me tell you this.

Because the camera is not like our human eyes, it can adapt, so sometimes the color of the things you shoot will be different due to factors such as weather and environment.

The white balance test is actually quite simple. You shoot at the white object to see if the **color you get is the same as the real thing. If the deviation is noticeable, then it's time to adjust the white balance.

In general, the higher the color temperature value (generally denoted by k), the more warm the color will be, and vice versa.

In general, cameras have automatic white balance. The white balance in the details depends on which camera you're using. Generally, it is set in the settings function.

How is the white balance of the camera adjusted? There are so many classifications, it seems that you have to study hard.

Camera White Balance Adjustment Method: Turn on the camera (preset adjustment method), press the WB key, and select the white balance mode required for the corresponding scene.

White balance, literally understood as the balance of white. White balance is a metric that describes the accuracy of white after the red, green, and blue primary colors are mixed in a display. White balance is a very important concept in the field of television photography, through which a series of problems can be solved in color reproduction and tone processing.

White balance is produced with the reproduction of color reality in electronic images, and white balance was applied earlier in the field of professional photography.

1. The color temperature of the flash is 5500K, and the skin tone of the 600D is just right when the LR is set to the white level to the flash, and the D800 must be set to about 5150 to be normal, and the same is true for the daylight mode.

2. It is very difficult to correct the color temperature without adjusting the color temperature directly to PS, which requires high-level retouching skills.

3. Optimization calibration: use vivid mode, enter the quick adjustment menu, adjust to: sharpness is 4, or 5, take portraits; Sharpen to 7, or 9, and shoot landscapes. Contrast nanoscale 1, brightness +1, saturation 1, hue 2.

4. White balance: use daylight mode, press the menu button to enter the white balance setting menu, set to B2, M1 in daylight mode, which is the general white balance mode for daily hang-up, specific shooting according to the environment, B2, 0 or B3, 0 or B3, M1 can be selected.

Wipe White Balance Settings under Annihilation 5 and NX2 Use the gray dot tool to use a straw to pick up the pure white parts to get accurate white balance.

There are three ways to set white balance in a studio:

1. If you're shooting in RAW format, it's relatively simple, find a light gray cardboard before shooting and put it in the light field (the cardboard you use to keep the fit when you buy a shirt is the most suitable). Then shoot two different **combinations, try to use the normal **, and shoot it appropriately large, but don't fill the whole picture. Then in the later stage, use special software to absorb the gray board to do white balance, which is also very accurate.

2. Take pictures with full pictures on the spot, which should be completed with the custom settings of the camera, which is more rigid, but it is also very effective, and it can also be flexibly used to shoot some very modified effects**.

3. After the camera is turned on, press the menu selection (modemenu) mode setting, and then select Picture to select WB, that is, white balance, white balance is divided into automatic, sunny, cloudy, iodine-tungsten lamp, white burn lamp for use in different environments.

The white balance of a DSLR camera means to shoot the balance of colors and restore the true colors. In daily shooting, you will encounter various light sources, and the color temperature is also different. Sometimes, the image is shot with a color cast, and white balance is used to solve this problem.

White balance effect: by controlling the color temperature, the color effect is very different**; Correct the color temperature and restore the color of the subject, so that the color of the picture shot under different light source conditions is similar to that of the human eye.

White balance is an extremely important concept for cameras. The so-called white balance is the camera's restoration of white objects. When people use the naked eye, the perception of the same color is basically the same under different lights, such as looking at a white object in the morning when the sun rises, and feeling that it is white; And in the dim light of the night, when you see a white object, you feel that it is still white.

This is due to the fact that the human brain has adapted to the color reproduction of objects under different light conditions during the growth process of human beings since birth. However, as a camera, it does not have the adaptability of the human eye, and in different light, due to the imbalance of the CCD output, the color of the camera is distorted: either the image is blue, or reddish.

The color temperature difference under different lights is very different, resulting in different color reproduction of the camera in different lights. To solve this problem, today's cameras have a white balance correction function that compensates for different color temperatures, so as to faithfully reproduce the color of the subject.
