Anti-Reflection
Specification::
Nano coatings on both sides of filter.
Digital water proof and scratch resistant multi-coating greatly reduces the appearance of lens flare and ghosting caused by reflections.
Ultra thin filter frame (Slim type filter only) to help avoid vignette on super wide angle lenses are also designed to hold a lens cap
Filters still retain front threads for a lens cap, a lens hood or even stacking a second filter
Description:
Neutral Density filter evenly reduce the amount of light passing through the lens without effecting color. Ideal for reducing bright light in large aperture situations when a narrow depth is field is needed. Neutral Density Filters are often used to achieve motion blur effects with slow shutter speeds
ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Neutral Density filters do not affect the overall coloration of the image.
Features:
High Quality Optical Glass 20 stop Neutral Density Filter ND 6.0
Increases control of depth of field
Eliminates overly bright, washed-out images. Balances exposures
Equally effective in color or black and white photography
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 Nano 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.
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.
