How to set the white balance of the camera?

Under different lighting conditions, the color of the target will change. In this respect, people are most sensitive to the change of white objects: under the indoor tungsten lamp, white objects will look orange, and the scenery photographed under such lighting conditions will look pale yellow; But if it is under the blue sky, there will be blue tones. The scenery taken under such lighting conditions will be blue. In order to minimize the influence of external light on the target color, the original color of the target can be restored under different color temperature conditions, which requires digital cameras to correct the color to achieve the correct color balance.

White objects reflect all the visible spectrum, so digital cameras set this as the standard. When manually adjusting the white balance, the white balance mechanism will try to modulate other colors other than pure white into a certain range of pure white. If this part is yellow, it will strengthen the blue to reduce the yellow in the picture, so as to obtain a more natural color. Digital cameras can correctly restore other colors of white objects under the same lighting conditions as long as they correctly restore the white objects when shooting them. So it's called white balance adjustment. It can be divided into automatic adjustment and manual adjustment. Manual adjustment is more accurate and the adjustment range is wider. Traditional cameras rely on different films (sunlight type, illumination type) or different color filters to achieve correct color balance.

Dynamic white balance

Automatic white balance is usually the default setting for digital cameras. There is a complex rectangular picture in the camera, and the white balance reference point in the picture can be determined, thus realizing the white balance adjustment. This kind of automatic white balance has high accuracy, but when shooting in light, the effect is poor, and on cloudy days, many automatic white balance systems have poor effects, which may lead to blue.

Fluorescent white balance

It is suitable for white balance adjustment under fluorescent lamp, because there are many kinds of fluorescence, such as cold white and warm white, so some cameras have more than one kind of white balance adjustment. The fluorescent lamps used in different places are different, so the "fluorescent" settings are different. The photographer must determine what kind of "fluorescence" the light is so that the camera can set the best white balance. Of all the settings, the "Fluorescent" setting is the most difficult to decide. For example, some offices and schools use various combinations of fluorescent types, and the "fluorescent" setting here is very difficult to handle. The best way is to "shoot".

Indoor white balance

Indoor white balance, or cloudy or cloudy white balance, is suitable for adjusting the light in the dark to the primary color state. Not all digital cameras have this white balance setting. Generally speaking, the outdoor time-white balance system is in the best state, and these settings are not needed. However, some manufacturers add these special white balance settings to cameras, and the use of these white balances varies from camera to camera.

control manually

This white balance has different names in different places, and they describe some white balance settings under ordinary lighting conditions. Generally speaking, users need to point out the reference point of white balance to the camera, that is, which "white" object is used as the white point in the picture. But the question is what is "white". For example, different white paper will have different white colors, some may be slightly yellow, and some may be slightly white, and the light will affect our "white" feeling. So how to determine "true white"? One way to solve this problem is to carry a standard piece of white paper with you and compare the subjects when shooting. This method works very well, so when it is difficult to decide this setting when shooting indoors, you may wish to set the white balance according to the "reference" white paper. When there is no white paper, let the camera aim at the object that the eyeball thinks is white to adjust.
