Artnr: 28365
Nattebilleder og astrofotografi lider ofte under uønsket lysforurening. Kviksølvdamp, natriumlamper og nogle lav-CRI LED-vejrbelysninger udsender bølgelængder, der skaber en glød på himlen. Den glød kan forhindre dit kamera i at fange stjerner og de sande nattefarver. NiSi Natural Night-filteret blokerer de mest almindelige bølgelængder fra lysforurening, så du får renere og mere nøjagtige farver i dine nattebilleder.
Denne 77mm-variant af NiSi Natural Night-filteret er lavet specielt til at forbedre billeder taget om natten. Fotografer og filmskabere kan bruge det til at reducere påvirkningen fra nærliggende gadelamper og andre kunstige lyskilder i natte-scener. Ved at begrænse de problematiske bølgelængder hjælper filteret kameraet med at gengive himlen mere troværdigt.
Ligesom andre NiSi-filtre er Natural Night fremstillet af præcisionsglødet optisk glas. Dets overflade er fint slebet og poleret for at bevare billedets skarphed. Denne bearbejdning understøtter den opløsning, som nutidens ultra-højmegapixel-kameraer kræver, og hjælper med at bevare fine detaljer i nattebilleder.
Filteret har NiSi’s NANO Coating-teknologi. Denne flerlagsbelægning reducerer overfladereflektioner, hvilket igen hjælper med at kontrollere ghosting og flare under natoptagelser. Belægningen indeholder også et beskyttende lag, der gør det lettere at tørre vand, støv og olie af uden at bekymre sig om at ridse glasset. Vigtigt er det, at NANO Coating opnår disse fordele uden at introducere farveforskydning eller tab af skarphed.

Question: Will this filter improve my night and astrophotography images?
Answer: Yes. The NiSi Natural Night Filter blocks the most common wavelengths from light pollution, which helps the camera capture cleaner sky tones and more accurate night colors when shooting night scenes or astrophotography.
Question: Does the filter affect image sharpness or color balance?
Answer: The filter is made from precision annealed optical glass with a finely ground and polished surface to preserve sharpness. NiSi’s NANO Coating reduces reflections while achieving this without a color shift or loss in sharpness.
Question: How does the NANO Coating help in practical use?
Answer: The multi-layer NANO Coating lowers surface reflections to reduce ghosting and flare. It also provides a protective layer that makes it easier to remove water, dust and oil from the filter surface without worrying about scratching the glass.
Question: Which filter sizes exist and which one is this listing for?
Answer: The NiSi Natural Night Filter is available in circular sizes from 40,5 up to 95mm. This specific product listing is for the 77mm size.
Question: Is the coating durable against environmental factors?
Answer: The filter has double sided, multi-layer coatings that are described as waterproof and oil resistant, which helps protect the glass and makes cleaning easier in the field.
