Tiffen 62OR21 62mm #21 Orange Filter

The Tiffen 62mm #21 Orange Filter is specifically engineered to enhance contrast and delineate tonal gradations in black and white photography. Its primary function involves selectively absorbing blue and blue-green wavelengths, effectively darkening blues, particularly evident in sky elements within landscape or aerial photography, as well as water features in marine compositions. Featuring a filter factor of 4.5, compensating for its impact necessitates an exposure increase of approximately 2 1/3 stops to maintain proper luminance levels.Tiffen 62OR21 Features:Enhances Contrast in Black & White PhotographySuitable for Landscape, Marine, or Aerial PhotographySelectively Absorbs Blue and Blue-Green WavelengthsIntensifies Dark Tones in Blue SpectrumUtilizes Advanced ColorCore TechnologyTiffen 62OR21 Specifications:Filter Type: Black & White Contrast #21 OrangeFilter Factor: 5x (2.3-Stop)Circular Size: 62 mm Filter ThreadFront Accessory Thread / Bayonet: 62 mmCoatings: Single-CoatingFilter Material: GlassRing Material: Aluminum Tiffen 62OR21 62mm #21 Orange Filter.
