What is the color temperature in the camera?

Color temperature-the color sign of light

Take pictures with black and white film, as long as the aperture is fixed according to the intensity of light (the brightness of the object). However, when shooting with color film and color camera, besides the correct exposure, we should also consider the color temperature of the light that illuminates the subject, otherwise, color photos or color TV images will have color differences, and the color of the scene cannot be correctly restored. What is color temperature? The concept of color temperature cannot be understood literally, it is not "the temperature of color". Color temperature is a sign indicating the spectral composition of white light source.

Simply put, if you use different color temperatures, the color of the picture will be different. It depends on the scene and the effect you want to shoot. Color temperature is actually white balance. If it's a SLR, it's better to customize it yourself, take a picture with a piece of white paper, define the white balance yourself, and restore the truth.
