Rosco Cinegel Tough MinusGreen 20x24" lighting filter

SKU CH-D4SX-T6SA8

A 20x24" color-correction filter that removes green casts from fluorescent light for accurate 5500K daylight balance

  • Corrects fluorescent green cast for natural skin tones
  • Transforms cool-white fluorescent output to 5500 K daylight
  • Deep-dyed CC30 Magenta equivalent ensures precise color balance
  • 55 % light transmission with only .9 stop loss
  • Tough construction withstands high heat for long set life

Professional Color Correction Filter

The Rosco Cinegel Tough MinusGreen is a 20x24 inch lighting filter built for photographers and videographers who must neutralise the green cast of US Cool White or daylight fluorescent lamps. It converts that output to a 5500 Degree Kelvin photographic daylight balance for accurate colour rendering.

Sustained Heat Performance

The deep-dyed construction withstands high temperatures during extended studio sessions without degrading colour accuracy. Consistent transmission is maintained across long shooting days, so the filter delivers reliable correction from the first frame to the last.

Transmission and Correction Limits

The filter provides 55% light transmission with a .9 stop loss, which defines the practical exposure adjustment required. It is the equivalent to a CC30 Magenta correction, so it cannot compensate for sources that need a stronger or weaker magenta shift.

Questions about this item

How much heat or power does the 20x24" filter add when used all day under hot studio lights?

The Tough MinusGreen is built to withstand high temperatures from continuous lighting, so it adds no extra heat or power draw of its own.

What lighting fixtures or holders do I already need to mount this 20x24" sheet?

You need a frame, gel clip or diffusion holder that accepts a 20 by 24 inch sheet; the filter itself has no built-in mounting hardware.

Will this CC30 Magenta equivalent filter work with my older tungsten or HMI heads without shifting color?

It is designed to correct Cool White fluorescent lamps to 5500 Degree Kelvin daylight; using it on tungsten or HMI sources will alter their color balance.
