Is the color temperature in photography just white balance? It is said that the color temperature of seascape shooting should be adjusted to 4000k K.

Color temperature is not white balance. The basic concept of white balance is that "white objects can be restored to white under any light source".

1. The color temperature in photography generally refers to the color tendency of light; This kind of light with partial color will affect the overall tone of photographic works; Such as blue, red, yellow and so on.

2. Observe the color temperature and see the ambient light, such as red and yellow at sunset, which is called "warm color" in painting, but in the definition of photographic color temperature, the color temperature of red is the lowest, that is to say, the flame temperature of red is the lowest. Blue is the standard "cool color" in painting, but it is the highest value in the definition of photographic color temperature. For example, on a sunny snow scene, the reflection of snow is blue, and the ambient air temperature is very cold, but the color temperature value is very high at this time.
