The Fire crest Soft Edge ND Grad uses Fire crest technology to create the world’s most neutral grad filter, and is the perfect complement to the Fire crest Neutral Density filters. Soft edge grads are versatile filters used to balance the luminosity of a bright sky with the terrain below. The soft edge makes it easy to place the filter in the scene, especially over undefined horizons (such as mountains).Fire crest Neutral Density is a revolutionary new type of ND filter from Format-Hitech. Rather than dyed resin, Fire crest is a carbon metallic coating used to create hyper neutral NDs. These circular ND filters are made from Schott Super white glass and feature rotating, stackable 7.5mm Super Slim rings. Fire crest Neutral Density filters are hydrophobic, anti-reflective and extremely flare resistant, which increases contrast and visual acuity in challenging lighting conditions. This 82mm Fire crest Soft Edge ND Grad filter reduces light by 2 stops at the top of the filter.
