This Firecrest Patrick Di Fruscia 100mm Signature Edition Pro Essentials Kit from Formatt Hitech contains two filters that can be used individually or in combination to improve the results of your photography by preventing overexposure, as well as a circular polarizer to prevent distracting reflections or glare. The included filters consist of an 82mm Firecrest circular polarizer, a 100 x 100mm Firecrest solid neutral density filter that reduces the amount of light entering a lens by four stops, and a 100 x 150mm Firecrest three-stop graduated neutral density filter that features a soft-edged line of transition between its dense and clear areas. Together, these neutral density filters provide a versatile solution for various lighting conditions and horizon lines.
To allow these neutral density filters to be placed in front of a lens, this kit contains a 100mm Firecrest Filter Holder that is designed to allow for the convenient use of up to two, 100mm-wide, 2mm-thick filters along with the included circular polarizer. This holder has its sides encased within a cover that helps to eliminate stray light, which could have unwanted effects on exposure, from coming in between any installed filters, as well as the filter holder and the lens behind it.
Use of the filter holder can be easily accomplished by first screwing an included 82mm adapter ring onto a lens with 82mm front filter threads. Step-up rings are also included to allow the adapter ring to be used with lenses that have 67mm, 72mm, or 77mm front filter threads; while additional step-up rings are separately available for lenses with 46mm, 52mm, 58mm, or 62mm front filter threads. After being fitted onto the adapter ring, the filter holder's pull-and-release locking lever helps to provide a reliable, yet adjustable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning.
An exclusive Patrick Di Fruscia booklet is also part of this kit, offering inspiration and insight into his photography.
Formatt Hitech Firecrest neutral density filters are constructed from Schott Superwhite glass for increased optical clarity and color fidelity. They are optimized for use with digital sensors and promote nearly flat attenuation of visible, UV, and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. This filter provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.
To prevent internal ghosting and reflections, the glass surfaces of each included Firecrest neutral density filter features 15 layers of anti-reflection coating. These coatings also offer greater protection to the filter and help it to stay clean for longer than with uncoated filters, resulting in an improved beading effect when in contact with water for greater cleaning efficiency. The neutral density substrate of a Firecrest neutral density filter is also sandwiched between two layers of glass, enhancing durability and reparability of accidental scratches.
