Description
This 100 x 150mm Red Diamond Hard-Edge Reverse-Graduated Neutral Density 1.2 to 0.45 Filter from Haida is compatible with the Haida 100 or 100-Pro Filter Holder. It can be applied to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.
This filter achieves its effect with a 1.2 band of density across its center region that provides a 4-stop reduction in light from entering a lens. This band extends approximately 15mm in both vertical directions. With a soft-edged line of transition, it tapers to a 0.45 density that provides a 1.5-stop reduction in light at the edge above it. Directly below the 1.2 band of density, it tapers to clear, with a hard-edged line of transition before the clear area.
The placement of a 1.2 band of density that tapers to a density of 0.45 above it with a clear area directly below, ...

Features
Scratch-Resistant Hydrophobic Coatings
- Compatible with Haida 100 or 100-Pro Filter Holder
- Effectively darkens bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image
- 4-stop band of density that tapers to a 1.5-stop density at the edge above it while directly above a clear area creates a neutral density pattern that matches the positioning of the sun when it is at, or immediately above, the horizon
- 4-stop band of density extends approximately 15mm in both vertical directions
- Density pattern corresponds to the brightness pattern of the sun when it appears at or is closer to the horizon as opposed to a higher angle, which creates an increase in brightness that is more prominent on both sides of the sun than above it
- Hard-edged line of transition between the 4-stop band of density and the clear area below it is useful for hard transitions between the sky and land
- 4-stop to 1.5-stop gradation with soft-edged line of transition is applicable to multiple regions of brightness within the sky
- Filter does not affect the overall coloration of the image
- Shock-resistant optical glass construction
- 10 layers of anti-reflective nano coatings on each glass surface prevent internal ghosting and 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 improved beading effect when in contact with water or oil for greater cleaning efficiency
- Rounded edges for easier placement within a compatible filter holder slot
- When combined with a compatible filter holder, included gasket helps to prevent light from coming in between the filter and the lens behind it, which can have an unwanted effect on exposure
- Metallic filter case for storage and transport
