The excellent finely ground and polished special glass is used as the basis for the new ND filter glasses. This guarantees the necessary optical quality and also does not have any adverse effect on a correspondingly high-quality lens
About B+W ND Filters | Neutral-Density Filter
Optical ND filters are an essential tool for photographers who want complete control over the exposure in their images. ND stands for "neutral density" and refers to the fact that these filters are designed to reduce the amount of light reaching the camera's sensor without affecting the color balance or sharpness of the image.
With the thin-film technology developed here, not only the pure ND filter effect comes into play, but a coating combination optimizes the ND filter. In addition to the filter effect, the coating combination contains a multi-layer anti-reflective component with 7 layers per filter side to prevent annoying reflections. An outer layer with the usual dirt- and water-repellent properties is applied as the final layer. This not only provides all-around protection for the filter, but also makes it easy to clean and maintain the filter pane. The light attenuation itself is very uniform over the entire visible range and produces optimally color-neutral image results.
Key Applications
- Reducing the amount of light entering the camera
- Suitable for both analog and digital cameras
- Selective sharpness by achieving larger apertures – ideal for portraiture
- Long exposures producing a cotton candy effect on moving water and deserted streets void of people and cars
- Wipe effects, continuous light trails
- Made in Germany
Please Note
ND filters must not be used for direct visual solar observation (risk of blinding). They let through UV- and IR-rays which harm the eyes. Special sun filters for direct observation of the sun are available from astronomy suppliers,
Tips & Tricks ND Filter
For beginners it can be a challenge to achieve optimal results with ND Filters at first. There are a few things to consider and often it is necessary to maintain perfect conditions over a longer period. With these tips, you’ll have everything you need to get fantastic shots right from the very beginning!
- Use a stable tripod. Again, good equipment is 50% of success
- Work in Bulb mode "B" for long exposures
- Use the remote control of your camera app
- Do not rely on the automatic mode but set the exposure values manually
- Use low ISO values and choose a small aperture
- Use Live View for control
- Use the RAW file format to make post-processing easier
- Cover the camera’s viewfinder while taking the photo
- Our B+W ND Calculator app will help you set the correct exposure times
- Remember to turn off the noise reduction program
Different types of ND Filters
There are many different types of optical ND filters available. the market, from thin and light to thick and more robust filters. No matter what type of ND filter you choose, it is important to think about factors such as filter strength, filter diameter and filter type to choose the right filter for your needs.
Filter strength Filter factor
Filter strength is measured in stops and indicates how much light is blocked by the filter. For example, an ND filter with a strength of på 3 stops reduces the amount of light reaching the sensor by 8 times, while a filter with a strength of 6 stops reduces the amount of light by 64 times.
Filter diameter
Filter diameter is important to think about to make sure that the ND filter fits your lens. It is important to check the diameter of the lens and choose a filter that matches this. It äis alsoå possible to use step rings or filter adapter to use a filter on several different lenses.
Different types of ND filters
There are alsoå different types of ND filters suitable for different types of photography. For example, a variable ND filter can be adjusted to provide different filter strengths, while a fixed ND filter provides a constant strength.
ND filters are indispensable tools
Optical ND filters are indispensable tools for landscape photographers who want to capture waterfalls or movement in the clouds, but can also be usable for portrait photography where you want to use more blur to create a soft background but need to Reduce the amount of light to avoid overexposure. With an optical ND filter, photographers can have full control over the exposure in their images and create fantastic effects.
For more than 90 years, B+W filters have been synonymous with quality and innovation. B+W has succeeded in establishing itself as one of the world‘s leading filter manufacturers. It has, for example, made decisive progress in surface coating. B+W is the first filter manufacturer in the world to offer MRC (Multi Resistant Coating). MRC nano coating is the most innovative development in thin-layer technology. The world-famous Käsemann type polarizing filter with its outstanding quality has been produced by B+W since 1989.
