Lee Filters - SW150 150x170mm Reverse-Graduated ND 0.9 Filter (3 Stops)

The NiSi Explorer Collection 100x150mm Nano IR Reverse Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop is part of our Explorer Series for made for adventure. The filters feature a special glass hardening process that makes them double the strength of typical glass filter. The Explorer series are much less prone to accidental breakage and perfect for active photographers. Double the Strength of Typical Glass Filter B270 Glass IR Layers for Accurate Color Low Reflection Nano Coating Compatible with 100mm Filter Holder systemsThe NiSi Explorer Collection 100x150mm Nano IR Reverse Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop 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. Reverse edged GNDs are similar to hard-edged GNDs except that the darkest part of the filter is at the transition point. These filters have a specific use for shooting at the light source where the light is harshest at the horizon and tapers off toward the sky. This type of filter is most appropriate for scenes which have a sudden transition from the foreground to the sky with the brightest part of the scene near the horizon. Most commonly, this would include landscapes with no elements protruding above the horizon such as a seascape looking toward the open ocean. They can be used shooting into the direct light where a sharp transition is needed.NiSi GND filters do not affect the coloration of the image, offer a true to life color and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. 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 a small aperture. NiSi GND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true to life color.The NiSi Explorer Collection is made from B270 tempered glass. It features the same Nano coating process as our optical glass filters. This filter is tempered and hardened making it much less prone to accidental damage but this does not mean it is unbreakable. After a long period of time, the hardening may decline. The NiSi 100mm filter system is great for cameras with lenses that have a standard filter thread from 49 mm to 95mm. Are They Shatterproof No. We introduced these filters for two reasons: To give you more options and to provide education in the market. B270 glass is a general purpose glass with good clarity and light transmission. It is used in many applications from high-quality touch screens and LCD covers to lens protection filters.B270 glass filters are a good quality glass filter which can be tempered or toughened, which has advantages. It is stronger than Optical quality glass and in most cases, it will survive drops from approx.. 1m onto concrete. However if dropped on a corner it may still chip and there is more risk of the lateral shock traveling through the glass and shattering it.The toughening process for this glass degrades over time. The time frame is impossible to measure and whilst it may never become an issue it is important for us to not make the claims of others. Whilst stronger to start with, over time the strength will degrade. This technology cannot be applied to high-quality optical glass, which is the reason they are not toughened. And for perspective, optical glass filters are very strong. Many of us have dropped a NiSi Optical Glass filter and it has survived with no damage. Is Image Quality Different In most cases, you may not see a difference. NiSi Optical quality filters give the highest image quality possible which is important considering the optical performance of today's lenses and the high resolution of modern sensors. For most photographic applications the image quality of B270 glass filters will be very good. For those demanding the highest possible quality image, sharpness and detail we would strongly suggest choosing our Optical glass filters. Why Are They Less Expensive B270 glass is a much more cost-effective glass to use that optical glass. For this reason, the cost of our Explorer filters is lower than our Optical quality glass filters. We decided to introduce these filters with a price that reflects the material used and not to over-inflate the claims or the price to the end user.
