Cokin Filter A122 Gradual blue 1

According to the classic rules of landscape layout, the sky occupies 3/5 of the space above the line of horizon, whether real or imaginary. In photography, this is interpreted by major differences in luminosity between the sky and the rest of the image. COKIN Graduated Filters, by reducing the difference, re-balance the luminosity between the upper and lower part of the image. They put an end to disappointment from washed-out skies and underexposed landscapes.
COKIN Blue Graduated Filters: By enhancing the blue of the sky, they underline the colours of mountain landscapes. They are also the filters for sea photography, where they intensify the white sparkle of breaking waves.
