Haida 100 x 150 mm Red Diamond Soft-Edge Graduated Neutral Density 0.9 Filter (3 stops)

This Haida 100 x 150mm Red Diamond Soft-Edge 0.9 Graduated Neutral Density Filter is compatible with a Haida 100 or 100-Pro filter holder. Helps darken specific areas of an image, such as bright skies, while allowing normal, unaffected exposure in other regions of the image. The filter is densest at the edge and tapers to lighten in the middle, with a smooth-edged transition line between the dense and light areas. A neutral density filter with a smooth-edged transition line can filter the sky while minimizing its effect on the ground. This is particularly useful when the transition between the sky and the foreground is indeterminate, such as images with fog, mist, or the canopy of trees. Neutral density filters do not affect the coloration of the image and this filter provides a reduction of up to 3 stops in the light entering a lens.
Haida Red Diamond filters are made of impact resistant optical glass. To prevent ghosting and internal reflections, while further enhancing clarity and color fidelity, each glass surface includes 10 layers of anti-reflective nanolayers. An additional 10 scratch resistant hydrophobic coatings further protect the substrate of a Haida Red Diamond filter and result in an enhanced pearl effect when its surfaces come in contact with water or oil, allowing for more efficient cleaning. Additionally, Haida Red Diamond filters feature rounded edges for easier placement within a compatible filter holder slot.
A metal box is included for storage and transport, as well as a gasket that blocks the light. This gasket forms a seal that is designed to prevent stray light, which could have unwanted effects on exposure, from getting between the filter and the lens behind it.
Compatible with a Haida 100 or 100-Pro filter holder
Darkens bright areas of an image, such as the sky, without affecting the rest of the frame
Provides up to 3-stop light reduction in selective areas
Smooth-edged transition line between dense and light areas
Useful for images where the transition between the sky and the foreground is indeterminate, such as images with fog, mist, or the canopy of trees
The filter does not affect the overall coloration of the image
Shock resistant optical glass construction
10 layers of anti-reflective nanolayers on each glass surface prevent ghosting and internal reflections, while further enhancing clarity and color fidelity
10 additional scratch-resistant hydrophobic coatings on each glass surface further protect the filter substrate and result in an enhanced bead effect when in contact with water or oil for increased cleaning efficiency
Rounded edges for easier placement within a compatible filter holder slot
When paired with a compatible filter holder, the included gasket helps prevent light from entering between the filter and the lens behind it, which can have an unwanted effect on exposure.
