Led to shoot the light color temperature 3000 k what do you mean who knows
- Color temperature is the most common said light source spectrum quality indicators. Generally expressed in Tc. Color temperature is defined in absolute blackbody, absolutely blackbody radiation and light radiation in the visible area all at the same time, the temperature of blackbody is called the color temperature of light source. Low color TPS source is characterized by energy distribution, relatively more red radiation, commonly referred to as "warm light"; Color temperature increase, energy distribution, the proportion of blue radiation increases, often referred to as "cold light". Some commonly used color temperature of light source are as follows: standard candle is 1930 k (kelvin temperature unit); Tungsten is 2760-2900 k; Fluorescent lamp is 6400 k; Flash is 3800 k; At noon the sun is 5000 k; Electronic flash light for 6000 k; The blue sky is 10000 k.s
