An 82C is a "cooling" filter. Whereas an 82A will raise the temperature from 3000K to 3200K, an 82C will raise the temperature from 2800K to 3200K. 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. Whereas the 81 Series of filters creates a feeling of warmth, the 82 Series creates a feeling of coolness.
