How to distinguish white light from warm light?
Light color refers to the "light source color" or "light color component" of the shooting environment formed by several light sources. In the field of photography, people often use "color temperature" to represent the change of light color components in an environment. Light color determines the overall tone tendency of photos, which is very helpful to express the theme. For example, red is warm, yellow is noble and white is pure.
2700K~3200K is yellow, 3200K~5000K is warm white, also called "natural color", 5000K~6500K is called white light, and above 6500K is called cold light. This light source is generally used for outdoor street lamps, factory buildings and front and rear lighting of automobiles.
You can refer to the color temperature chart:
Extended data:
Color temperature is expressed by absolute temperature K (Kelvin), which means that when the standard blackbody (such as iron) is heated, when the temperature rises to a certain extent, the color begins to change from red to light red → orange yellow → white → blue white → blue. By gradually changing the characteristics of this light color change, the light color of the light source is the same as that of the black body at a certain temperature, and we call the absolute temperature of the black body at that time the color temperature of the light source.
When the color temperature is below 3000K, the light color begins to turn red, giving people a warm feeling. When the color temperature exceeds 5000K, the color tends to be blue, giving people a cold feeling.
Generally, the color temperature of 2700K to 4000K is the most suitable for household lighting, because this color temperature gives people a warm, warm and pleasant feeling.
