Color temperature of 10,000 Kelvin, matching clear blue sky — very cool, bluish light with no direct sunlight.
Definition
10000K refers to a color temperature of 10,000 Kelvin – extremely cold, bluish light. This color temperature corresponds to a heavily overcast sky or shade in bright daylight.
Practical Application
10000K light is used in the following scenarios:
- Color Correction: Correcting overly warm light sources with CTB filters
- Light Control: Simulating extreme daylight situations
- Effect Design: Cool atmospheres for thrillers, sci-fi, or medical scenes
- Efficiency Improvement: Avoiding post-production color correction
Technical Details
Important technical characteristics:
- Generated by daylight lamps with CTB 1/2 or CTB 3/4 filters
- LED panels with adjustable color temperature up to 10000K
- Reduces light output by 0.5 to 1 stop due to filter use
- Measurable with a color temperature meter
Practical Tips
- Set camera white balance to 10000K or adjust manually
- Perform exposure metering after filtering
- Store CTB filters away from UV protection
- Adjust other sources accordingly in mixed lighting
Professional Standards
In film production, 10000K light enables:
- Consistent color reproduction under varying outdoor light conditions
- Quick adaptation to natural shadow temperatures
- Reduced color grading time
- Broadcast-compliant color temperatures
