FORMATT - Filter ND Grad 0.9 (Hard Edge Vertical) (3 stops) 4x5.65"

Description

Neutral Density (or ND) filters produce a grey neutral tone and are used in photography to reduce light, enabling more control over exposure and depth of field without affecting color contrast. ND's are also available in graduated filters, both in hard and soft edge. These filters are clear in the bottom half of the filter with a gradual transition to the ND effect in the top half. They are primarily used for light reduction in skylines of landscape shots. Graduated ND's are available in Soft Edge or Hard Edge varieties. Soft edge grads have a smooth transition from clear to ND. Hard edge grads have a more defined hard lined transition and are usually used for longer focal lengths. The 0.9 filter reduces light by 3 stops. The filter is also available in 100mm, 144mm, 127mm and 168mm sizes. Formatt-Hitech glass filters are made from the world's highest quality optical glass, Schott Superwite.
