for filmmakers and photographers, it is important to know that different lighting conditions, different color temperatures have. Clearly visible in this example is interior shots, which gets in the film often has a reddish-yellow hue .
available in the following table some light situations with the corresponding color temperatures:
light source color temperature
bulb 100 W 2800 K
halogen lamp 3200 K
Fluorescent 4000 K
midday sun 5500-5800 K
flash picture 6000 K
If you change the color temperature of 3000 K to 8000 K, then changes the color impression of red after yellow on white towards blue . get
white balance with the camera
To under different light conditions is no "artificial" red-yellow or blue colors, a white balance help. It is(eg directed wall), the camera at a white object and carried out the white balance (to read the instructions in the manual of the camera). The camera then filters out the corresponding color components.
mixed interior and natural light
critical especially in recordings which are light and interior light are mixed. (Eg by sunlight that shines through a window into a space) then it is more useful if you darken the room and everything lit with a color temperature.
