Firecrest ND is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a rare earth metal 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. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared.
The Little Stopper can give increased flexibility with exposure lengths in the lower light at the start and end of the day. This often means that detail and texture can be retained in areas of movement such as the sky and water, while still conveying a sense of time passing.
