Professional lighting equipment or technique used in film and television production.
Definition
Full Minus Green is a correction filter that reduces the green component of artificial light. The filter balances the color temperature of fluorescent tubes and HMI lamps to daylight or tungsten light.
Practical Application
The filter is used in the following situations:
- Color Correction: Removal of the green cast from fluorescent tubes and energy-saving lamps
- Light Control: Matching different light sources on set
- Effect Design: Warm lighting mood without a green cast
- Increased Efficiency: Less color correction in post-production
Technical Details
Technical properties of the filter:
- Magenta tint compensates for green spectral components
- Available in various density levels (1/8, 1/4, 1/2, Full)
- Light reduction by approx. 1/2 stop at Full strength
- Material: Polycarbonate or gelatin
Practical Tips
- Perform exposure measurement after applying the filter
- Test different density levels in mixed-light situations
- Adjust the camera's white balance accordingly
- Protect the filter from heat and UV radiation
Professional Standards
The filter is part of the basic equipment for:
- Consistent color temperature with fluorescent lighting
- Quick correction without setup changes
- Reduced post-production costs
- Broadcast-compliant color values
