Haida Neutral Density Filter is a solid neutral density filter providing a solid stop exposure. This solid density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required.
By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the overall coloration of the image.
The Water Proof and Scratch Resistant Multi-Coating is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.
Haida Neutral Density filters are constructed from high quality optical glass for increased optical clarity and color fidelity. They feature an aluminum filter ring for durability.
Haida Neutral Density Filters? Factors:
Neutral Density, Exposure Adjustment, Light Transmission
ND0.3 (2x), 1 stop, reduces ISO by 1/2, 50%
ND0.6 (4x), 2 stops, reduces ISO by 1/4, 25%
ND0.9 (8x), 3 stops, reduces ISO by 1/8, 12.5%
ND1.8 (64x), 6 stops, reduces ISO by 1/64, 1.0%
ND2.7 (400x), 9 stops, reduces ISO by 1/500, 0.25%
ND3.0 (1000x), 10 stops, 0.1%
Neutral Density Filters Have Four Main Uses:
1. To enable slow shutter speeds to be used, especially with high speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars.
2. To decrease depth of field by allowing wider apertures to be used, this helps separate subjects from their background.
3. To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation.
4.To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes, this could cause over-exposure.
