Magenta correction gel that removes green cast from fluorescent, discharge, and budget LED sources (approx. CC30 magenta).
Overview
"Full Minus Green" (also "Full Minusgreen") is a magenta-colored correction filter (gel) that is stretched in front of a light source to compensate for the green cast from fluorescent tubes, discharge lamps, and many inexpensive LED lights. Such sources have a green peak in their spectrum, which appears as an unpleasant green veil on film and sensor; the magenta of the filter is the complementary color to green and neutralizes this cast. "Full" denotes the full correction strength; in addition, partial strengths (1/2, 1/4, 1/8) exist for weaker green components.
The filter is not a single manufacturer's product but a standardized correction class offered by several manufacturers with nearly identical effects. Common codes are LEE 247 or Rosco E-Colour 247 ("Full Minus Green"), as well as Rosco Cinegel 3308 ("Tough Minusgreen") with a more heat-resistant, deep-dyed base.
Technical Data
The correction strength for all "Full" variants nominally corresponds to a CC30 magenta camera filter. The values vary slightly depending on the product line:
| Product | Code | Correction Equivalent | Transmission | Light Loss |
|---|---|---|---|---|
| LEE / Rosco E-Colour Full Minus Green | 247 | approx. CC30 Magenta | 59.1 % | approx. 0.8 stops |
| Rosco Cinegel Tough Minusgreen | 3308 | approx. CC30 Magenta | 55 % | approx. 0.9 stops |
Available forms are typically sheets (e.g., 21" x 24" or approx. 0.53 m x 0.61 m) and rolls (e.g., 48" x 25 ft or approx. 1.22 m x 7.62 m). The Cinegel series uses a deep-dyed, heat-resistant polymer base for use close to hot lights.
On-Set Usage
- Correction of US Cool White and daylight fluorescent tubes, as well as industrial discharge lamps that exhibit a green peak.
- Removal of the green component from inexpensive LED sources with poor spectrum or low CRI.
- Matching practical lights and existing overhead lighting to the rest of the lighting setup to achieve a consistent white point.
Since the filter costs approximately one stop of light, it is often placed directly on the source (e.g., as a sleeve over fluorescent tubes) or stretched in frames in front of the fixture. If "Full" correction is too strong, partial strengths are used; the counterpart "Plus Green" (green) is used to match daylight or artificial light sources to existing fluorescent light.
