How to set the white balance of digital SLR camera more accurately? Indoor is studio light, outdoor is natural light! I need specific instructions. Thank you.

1. In different light, the camera must be equipped with different white balances, otherwise the color tone will definitely be off.

2. At night, the lights are dim. According to the theory of white balance, the color temperature is low, and the candlelight is1000 k. When shooting with high color temperature white balance in the sun, the background tends to be red, which is proved by experiments.

3. Always set the front white balance at D0 before shooting, or choose the automatic white balance (which is very close to the white balance set by yourself).

4. When the light is dim, it may not be good to adjust the white balance. Need to expose M file, increase the exposure time, otherwise it will not be adjusted. Many cameras provide preset white balance values for the most common lighting conditions. When starting photography in a new place, first take a few photos to determine the WB setting that should be used. ● Automatic WB(Atuo WB, AWB): This default setting should be able to achieve good results under good lighting conditions, especially when there are some white or neutral gray objects in the scene. Automatic WB usually has a wide range of color temperatures. The better the automatic WB, the less you have to worry about setting adjustments. ● Incandescent lamp/tungsten lamp: In order to improve the color temperature, digital cameras usually adjust their own WB preset values. This setting can be used in the area of about 3000~3500K, which can compensate filament bulbs and tungsten filament studio lamps at home. ● Fluorescence: Downlight has a wide range of colors, including warm color, sunlight color, cool color, etc. Therefore, it can only be estimated that the preset value covers the range of 4200~4500K K. In fact, this setting can cover a wider range and can also adjust the important green/magenta balance. ● Sunny day/sunlight: This means that the scene is in direct sunlight, including the range of 5000~5500K K K. ● Flash: The color temperature of electronic flash is similar to that of sunlight, but it may be slightly colder (bluer). This setting may be effective when using the flash assembly provided by the camera manufacturer. ● C l o u d y day (cl o u d y): This setting is used for blue scenes of 6 0 0 0 ~7000K, usually in rooms without artificial lighting or open areas without direct sunlight. ● Shading: Many popular cameras don't have this item. This setting is used in the range of 8000~ 10000K to warm the colors of indoor scenes and shadows in a very blue sky, or to shoot in the early morning or evening (without direct sunlight).
