Product Introduction
A 3 stops ND filter ND8 OD0.9 is a relatively dark filter that blocks about 75-80% of the incoming light, equivalent to 3 stops of light reduction. An ND0.9 filter will allow you to decrease your shutter speed by three stops while maintaining the same exposure. For example, if without the filter, your proper direction is 1/250s at f/4, with an ND0.9 filter, you can slow your shutter speed to 1/30s to achieve the same exposure.
Experience creative control over your daytime exposures with UVWAVETEK’s ND filters! Our ND filters are of high optical quality, using ultra-slim frames to avoid vignetting on wide-angle lenses and glasses that provide maximum light transmission and optical clarity. Moreover, nanotech anti-reflective coating on both sides can reach up to 16 layers, with the black aluminum frame as an optional choice. For more details, please send us an inquiry.

Applications -- Sunset
A 3-stop neutral density filter (ND0.9) is ideal for sunset photography as it allows for more creative control over exposure. By reducing the light entering the lens by 75-80%, an ND0.9 filter enables a slower shutter speed without overexposing the image. This lets you achieve a softly blurred, dramatic effect from moving clouds or foliage in the breeze. It also helps intensify the vibrant colors in the sky by permitting the camera to absorb more of the ambient light.
With less light entering the lens, an ND0.9 filter provides more flexibility in composition. You have longer to frame and capture your image as the sun descends below the horizon. You can also use a broader aperture to obtain a shallow depth of field for a more dimensional photograph, which is usually tricky when shooting directly into the bright sunset.


ND filter VS UV filter
ND filters and UV filters are two different types of lens filters:
Neutral Density (ND) filters reduce the amount of light entering the lens. UV filters are mainly used to protect the lens and reduce haze. Some key differences:
|
|
Neutral Density (ND) Filters |
UV Filters |
|
Purpose |
Reduce the amount of light for creative effects like long exposures, shallow depth of field, and motion blur |
Protect lens from damage; reduce UV haze |
|
Light Reduction |
Varying amounts (measured in stops) |
No significant reduction |
|
Image Effect |
Darkens scene; allows for motion effects and wider apertures |
Little to no effect |
|
Construction |
Neutral gray tinted glass |
Colorless glass blocks UV |

Cost |
Higher-quality models cost more |
Typically very affordable |

Necessity |
Optional based on creativity |
Can be essential for lens protection |
As you can see from the chart, while ND and UV filters may look similar and attach to the end of your lens, they serve entirely different purposes. 3 ND filter ND8 OD0.9 actively manipulate the amount of light entering the lens for creative photographic effects. UV filters protect the lens from damage and environmental factors with little impact on the image.
Using ND and UV filters together, you can achieve lens protection and enhance your creative possibilities through prolonged exposure and shallow depth-of-field photography. But understanding how these two types of filters differ in construction and intended purpose will help ensure you get the desired results from adding filtration to your lens.
