Who can help me explain the color temperature including indoor and outdoor! ~

Color temperature is a measure of light color of light source, and the unit is K (Kelvin). ?

For our vision, the low color temperature light source is characterized by relatively more red radiation in the energy distribution, which is usually called "warm light"; After the color temperature rises, the proportion of blue radiation in the energy distribution concentration increases, which is usually called "cold light".

The color temperature of some common light sources is: standard candle light is 1930K (Kelvin-day); Tungsten lamp 2760-2900K；; The fluorescent lamp is 3000 k; Flash 3800 k; The sunshine at noon is 5400 k; Electronic flash 6000 k; The blue sky is 12000- 18000K.

Outdoor color temperature:

The outdoor color temperature setting is generally around 5500, depending on the shooting time. After changing the color temperature, we need to pay attention to the influence of color film correction lamp on people. Generally, the color temperature of outdoor photos taken by a camera can be set to automatic, and a color temperature table can be used if precision is sought.

It depends on what tone the photographer wants to shoot. Take the cool color tone to reduce the color temperature value, and the heating color tone to increase the color temperature value, depending on personal hobbies.

Indoor color temperature:

In indoor lighting, the main light source is neutral color temperature (about 4000K) and the auxiliary light source should be warm light (about 3000K).

In addition, from the purpose of the room, the study, living room and kitchen can use cold light (color temperature above 5000K), while the bedroom, bathroom and balcony should use warm light. The most important thing is to design and choose according to personal preferences.

The color temperature is just the opposite of what ordinary people think of as "warm" and "cold". For example, people usually think that red, orange and yellow are warmer, while white and blue are colder. In fact, the color temperature of red is the lowest, and then gradually increases to orange, yellow, white and blue, and blue is the highest color temperature.
