The Kodak 82 Series of 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. Kodak 82 filters are available in grades from 82 through 82C, with 82C having the greatest cooling effect.
Kodak gelatin filters are available in 3 x 3" (75 x 75mm), 4 x 4" (100 x 100mm), 6 x 6" (150 x 150mm) and 14 x 18" (35.6 x 45.7cm).
