B+W 810 MASTER, 5,5 cm, Kamerafilter med neutral densitet, MRC (Multi Resistant Coating), 1 styck

With a light reduction of ten f-stops, this ND filter delivers a further intensification compared with the B+W ND 106. Running water virtually transforms into mist. People walking on streets become blurred and indistinct or even invisible. In some cases this involves extremely long exposures of up to one minute. A stable tripod is essential.

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.

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.

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
- Use sufficiently stable tripod
- Work with “B” bulb for long exposure times
- Use remote control with camera-app
- Set exposure values manually (no full-auto program)
- Select low ASA values and a small stop
- Choose Live-View for control
- Deactivate noise reduction program
- Use RAW format to attain optimum editing conditions
- Cover camera viewfinder during photo shoot
- B+W ND Calculator App helps to find the right exposure time
