The 82 series are light balancing filters used to increase the color temperature slightly for a cooler tone. This light blue filter absorbs the excessive yellow-red light from daylight in the morning and evening hours and keeps skin tones close to natural. Optiflex 82 filters are available in grades from 82 through 82C, with 82C having the greatest cooling effect. Whereas the 81 Series of filters creates a feeling of warmth, the 82 Series creates a feeling of coolness.
Optiflex resin filters are made from durable, lightweight, optical resin and are slightly thicker than standard gelatin filters. These filters are available in 3 x 3" (75 x 75mm) and 4 x 4" (100 x 100mm) and are 0.4mm thick.
