Formatt Hitech 3 in 1 100x150mm ND Grad Kit Hard Filter System ( ND0.3 HE, ND0.6 HE, ND0.9 HE )
ND Grad Hard Edge Resin Filter Kit
This Grad Kit contains the most commonly used densities of the Hard Edge Neutral Density filter - 1-3 stops (0.3, 0.6 & 0.9). Hard Edge ND grads feature a neutral gray effect at the top of the filter that sharply transitions to clear at the center of the filter. The main function of a graduated ND is to balance the luminosity of the sky to the terrain below. The hard edge grad primarily used in photos that feature a defined and uninterrupted horizon, such as a seascape. Formatt-Hitech filters are made from the highest quality 1.5mm optical resin.
Graduated filters have an effect that occurs on one area of the filter and transitions to clear on other areas of the filter. Typically graduated filters are used to enhance the sky or terrain, or balance the luminosity of the sky to the luminosity of the terrain. Formatt-Hitech also make hard and soft edge grad filters in a variety of colors.
Hard Edge Grads feature a defined transition between the clear and the ND. These filters are ideal for reducing luminance of the bright sky over a defined horizon line, such as a seascape.
Formatt-Hitech’s resin filters are ultra flat, have excellent contrast and are completely transparent to the visible light spectrum. Formatt-Hitech’s resin has the highest scratch resistance of any non-glass optical material and it’s resistant to most solvents, chemicals, aging and material fatigue. Because of the ruggedness, light weight and portability, resin filters are a great choice for photographers and HDSLR filmmakers. Resin filters are dyed using our exclusive Absorbing Cell Technology process.
