Rosco - 1/8 CTB Tungsten Correction Filter - Cinegel #3216
Rosco's Cinegel Range of filters were introduced in 1970 and offer over 75 tools for correcting light. The 1/8 CTB #3216 filter is a tungsten filter that raises color temperature. Typically, they are used on tungsten/halogen sources to balance daylight; they raise the color temperature from 3200K to 3300K. This filter offers a partial conversion to compensate for voltage reduction, or to boost aging HMI lamps or household incandescent sources. It has a deep-dyed base for heat stability and superior color transmission.
