The photos taken by my camera are yellow.

Maybe it's the color temperature. Please check the white balance setting of the camera. Normally, the white balance is set to automatic. Only when the camera's color temperature setting is consistent with the environment setting can the picture color reproduction be accurate. If the white balance of the camera is set higher than the color temperature of the scene, the photo will turn yellow. The white balance settings of digital cameras are usually as follows:

Automatic white balance

This setting is the default setting for the camera. 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. Generally speaking, the accuracy of automatic white balance is still relatively high, but when shooting outdoors and under strong light, its effect is somewhat unsatisfactory. On cloudy days, many automatic white balance systems are extremely poor, which may lead to blue.

Tungsten light-white balance

Tungsten lamp is also called "incandescent lamp" or "indoor light" in some cameras. This setting is generally used in light bulb lighting environment (such as home). When the white balance system of the camera knows that it will not shoot with a flash in this environment, it will start to determine the position of the white balance. It must use this setting when taking pictures indoors without a flash.

Fluorescent white balance

This setting will adjust the white balance under the illumination of fluorescent lamp, because there are many kinds of fluorescence, including cold white and warm white, so some cameras have more than one kind of fluorescent 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".

Two photos taken under cold fluorescent lamp with different white balance settings, the left picture shows the automatic white balance setting, and the right picture shows the fluorescent white balance setting.

Sunny, cloudy, dark or outdoor white balance

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 have added these special white balance settings to cameras, and the use of these white balances varies from camera to camera. Please refer to the User Manual for specific use.

Manually adjust the white balance

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.

In fact, the white balance adjustment of digital cameras is equivalent to choosing different films or different color filters in traditional cameras. Their essence is to control and correct the color temperature. The difference is that digital cameras need programming, and traditional photography is more human factors. Just as blue images can sometimes be photographed with optical film, sometimes the ideographic function of color language can be enhanced without setting white balance, so it is not necessary to adjust white balance from time to time.
