Process of adjusting the camera's color sensitivity to match the color temperature of the light source
Ensures neutral colors (whites) appear white in the final image or video
Compensates for the varying color casts produced by different light sources
Measured in Kelvin (K) units, representing the color temperature of light
Importance in filmmaking
Maintains color accuracy and consistency throughout a scene or production
Prevents unnatural color casts that can distract viewers or misrepresent the subject
Enhances the overall visual quality and professionalism of the footage
Facilitates easier color grading and post-production processes
Crucial for accurately representing skin tones and other important visual elements
Color temperature basics
Refers to the warmth or coolness of light emitted by a source
Measured on the Kelvin scale , ranging from warm (reddish) to cool (bluish) tones
Lower Kelvin values (2000-4000K) indicate warmer light (candles, incandescent bulbs)
Higher Kelvin values (5000K and above) represent cooler light (daylight , fluorescent lamps)
Human eyes naturally adjust to different color temperatures, while cameras require manual or automatic adjustment
Color temperature scale
The color temperature scale provides a standardized way for filmmakers to understand and communicate about light characteristics
Journalists must be familiar with this scale to quickly assess and adjust for various lighting conditions in the field
Understanding the color temperature scale aids in selecting appropriate white balance settings and achieving consistent color across different shots
Kelvin measurement system
Numerical scale used to quantify the color of light sources
Named after physicist William Thomson, 1st Baron Kelvin
Ranges from approximately 1,000K to 10,000K for common light sources
Lower values represent warmer (more orange/red) light
Higher values indicate cooler (more blue) light
Warm vs cool light sources
Warm light sources emit light with a reddish or yellowish tint
Includes candles (1,500K), incandescent bulbs (2,700-3,300K), and sunrise/sunset (2,000-3,000K)
Cool light sources produce light with a bluish tint
Includes noon daylight (5,000-5,500K), overcast sky (6,500-7,500K), and clear blue sky (10,000-15,000K)
Understanding the distinction helps journalists anticipate and adjust for different lighting scenarios
Common color temperatures
Candlelight: 1,500-2,000K
Tungsten bulbs: 2,700-3,300K
Fluorescent lights: 3,000-4,500K
Daylight (noon): 5,000-5,500K
Overcast sky: 6,500-7,500K
Shade: 7,000-8,000K
Clear blue sky: 10,000-15,000K
