P121F Graduated Grey ND Filter

Progressive graduation from the bottom to the top of the filter, same colour & tone than 121. 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 underexposedlandscapes. Since the sky and the clouds are changeable and varied, Cokin Graduated Filters invite you to imitate them in your own interpretation of colours. Recomended size for larger diameter lenses up to 82mm. Recommended for focal lengths from 28mm onwards (35mm format).

How the Cokin System works

The Cokin Creative Filter System consists of three main components: A filter holder / Adapter ring and a Filter.

1. Screw the adapter ring onto your lens.
2. Slide the filter holder on the adapter ring until it snaps in place. The filter holder is now solidly attached to the lens, yet it can rotate both left and right.
3. Slide the filter into one of the filter holder slots. The one closest to the filter holder housing is the narrowest; it allows the use of round filters with notched edges (polarizer, star filters..). The two central slots are intended for square filters. The outer slot can be used either for an additional filter or for a coupling ring.
