MPS Sticky Fill Flash Correction Filters
• Use a Rosco Cinegel 3304 (Tough Plusgreen), which is equivalent to a Kodak 30G filter, to convert a flash to a florescent color temperature.
• Use a Rosco Cinegel 3401 (Roscosun 85), which is equivalent to a Kodak 85B filter, to convert flash to a tungsten color temperature (3200°K).
• Use a Rosco Cinegel 3409 (Roscosun 1/4 CTO), which warms the light by 1000K, to make the light from a flash less blue.
