The 3 x 3" #21 Orange Wratten 2 Optical Gel Filter from Kodak is a bright orange filter that darkens blue, violet, green and yellow-green. It is particularly useful for all landscape and architectural photography (on black and white film) requiring vivid contours. The sky is distinctly toned with the clouds clearly contrasted against it. It is suitable for landscapes and nature scenes.
