Filter Effect
This subtle blue filter reduces red color cast in the early morning or late afternoon. It increases color temperature by approximately 200 K. No exposure compensation is required.

Strong warm color casts caused by low sun angles in the morning and evening are gently reduced without completely neutralizing the characteristic lighting of these times of day. Typical applications include:

• When the sea appears slightly colorless due to unfavorable sun position

• When original colors of sunlit buildings should be reproduced accurately

• When a generally cooler color balance is desired than is naturally present
