NiSi 長期以來 對於濾鏡使用的研發,以及與國際名攝影師共同研發,依據鏡頭口徑以及最大通光量測量研究得出,約獨特的漸變區域是最符合攝影需求的利用漸層區間的改變,讓各未使用者在反差的控制上更得心應手更凸顯天空層次感 降低反差 不失前景光感及細節
與原先soft nano軟漸變差別在於標準漸變款拉長灰色區域( 拉長了上方ND減光區間在漸變區域
),適合拍攝上方天際線延伸出來卻又佔據畫面比例小的物體(如山峰、建築物等)
通過使用ND濾光片,相機易受紅外線照射,在小光圈下拍攝時會使照片產生不需要的紅色。NiSi在該濾光片上增加了紅外線防護塗層,有助於消除透過鏡頭的紅外線,帶回自然色彩。
The 150x170mm Nano IR Medium Graduated Neutral Density filter from NiSi is
specially designed for landscape photographers. This filter is made from high
quality optical glass (not resin) with nano coating to prevent losing any single
bit of detail.
The NiSi Medium GND Filter is a rectangular filter that helps to darken specific
areas of an image, such as bright skies, while allowing for a normal, unaffected
exposure in the other regions of the image. The filter is densest at the edge
and tapers to clear by the middle, with a medium-edged line of transition
between the dense and clear areas. A neutral density filter with a medium-edged
line of transition is particularly useful for images that feature buildings,
mountains and other elements that protrude into the skyline.
By using neutral density filter the camera is vulnerable to infrared light which
will cast the unwanted red color to the photos when shooting at small aperture.
NiSi added the infrared protection coating layer to this filter which help to
eliminate the infrared light through the lens to bring back the nature colour.
Perfect to balance the exposure when buildings, mountains and other elements
protrude into the skyline
Optical glass for high definition
Waterproof and low reflection Nano Coating
True in life colour
Compatible with NiSI 150mm Filter Holder systems
