2x5" Rosco Cinegel Speedlight gel colour correction filter kit - CTO CTB CTG plusgreen

This filter pack contains 9 Rosco colour correction gels designed to convert the light coming from your flash from 5500K daylight to a colour which matches the three other most common light sources : tungsten, overcast daylight and fluorescent lighting. This allows you to balance your flash lighing with ambient without introducing an unpleasant colour cast

The gels are specially cut to 5cm x 12.5cm (2" x 5") to suit almost any speedlight flash (unlike the Rosco sample gels which are too small to provide full cover for most flashes). The filters can be easily attached to your flash with Velcro (sold seperately). The velcro can also be used in conjunction with the Honl speedstraps.

Rosco gels are highly heat resistant, however some flashes can get very hot especially on full power. To avoid damage, arc the gel over the front element of the flash and leave a small gap of air for the flash energy to dissipate.

Kit includes 1 each of the following Rosco gels:

Full CTO (converts 5500K to 2900K)
1/2 CTO (converts 5500K to 3800K)
1/4 CTO (converts 5500K to 4500K)

CTO (Colour To Orange) gels are used to decrease the colour temperature of your flash to match tungsten and incandescent lighting i.e. normal household lights or halogens.

Full CTB (converts 5500K to 7800K)
1/2 CTB (converts 5500K to 6400K)
1/4 CTB (converts 5500K to 5800K)

CTB (Colour To Blue) gels are used to increase the colour temperature of your flash to match overcast lighting outdoors.

Full Plusgreen (Adds green to balance with Cool White or Daylight type fluorescent)
1/2 Plusgreen (Adds partial green to balance with fluorescents and discharge lamps)
1/4 Plusgreen (Adds partial green to balance with fluorescents and discharge lamps)

Plusgreen filters add varying amounts of green to match different fluorescent and discharge lamp light sources.
