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 is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Fire crest is a carbon metallic coating used to create hyper neutral NDs. The filters are made from 2mm thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Fire crest Filters are neutral across all spectrums, including UV, visible, and infrared. This 150x170mm Fire crest Soft Edge ND Grad filter reduces light by 5 stops at the top of the filter.
