Is the white balance and color temperature of a digital camera the same? How to adjust the white balance correctly to adjust the cold and warm colors of the picture?

Many people mistakenly regard the white balance and color temperature in digital cameras as the same thing. Actually, they are not the same concept at all. White balance is an index of color correction in digital products, and color temperature is a measure of color components in the picture. When we use the camera, we need to adjust the parameters of white balance to achieve good cold and warm colors of the picture, and use the principle of color mixing to correct the picture to make the color of the picture more vivid. White balance in digital camera is an index of color correction. When we take a picture with a camera, we need to adjust the white balance to make the picture better. This indicator for color correction itself is a mixture of red, blue and green. When we shoot outdoors, if we shoot directly with the camera, the color of the scene will turn yellow relatively. However, the color problem can be restored by the principle of white balance correction. No matter under any light source, the true color of the object can be adjusted back to achieve the best effect of the picture.

Color temperature, a measurement unit of light color by digital camera, and another measurement unit of light color is called color temperature, which is a measurement method. This concept originated from the fields of physics and astronomy, mainly through the light heated to different degrees by black objects, and this color temperature is mainly related to the temperature of the black body, and the measured component is the color contained in the light. Color temperature can also be explained by the range of color changes that human eyes can feel under different light waves. Generally speaking, the ascending order can be orange, red, white and blue.

Both white balance and color temperature can be adjusted to achieve the effect of retouching. In a digital camera, both the white balance and the color temperature can be adjusted, aiming at making the shot photos more truly restore the original film. By adjusting, white balance can make the image more vivid, and adjusting automatic white balance or shadow mode can restore the image better. In the adjustment of color temperature, we can express the color change through the color temperature. If we want to shoot warm air tones, we need to mix colors and correct them to achieve a balanced effect.

White balance adjustment corrects the different effects brought by white balance and color temperature. When people adjust photos, they can also adjust these two measurement units to realize the corresponding picture correction. For example, when shooting warm air scenes, they can adjust the white balance to achieve color mixing. If the photo is blue, then we need to adjust the parameters of white balance and reduce the color temperature to make the picture look warmer. We can improve the white balance when shooting some works with darker colors.

Under normal circumstances, our camera will have a white balance preset. The main purpose of these white balance presets is to enable us to take beautiful photos in different environments and light. However, photographers who have certain requirements for white balance and color temperature can adjust and set the white balance manually to obtain more accurate photo colors. If they want to show what the photo is like, they can set the parameters of color temperature and white balance to achieve the effect of retouching.
