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, ageing 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. Formatt-Hitech filters are made from the highest quality 1.5mm optical resin.
Soft Edge ND grads feature a neutral grey effect at the top of the filter that gradually transitions to clear at the centre of the filter. The main function of a graduated ND is to balance the luminosity of the sky to the terrain below. The soft edge grad is the most popular and most versatile grad we make because it’s easy to blend the gradual transition into an undulating horizon.
Hard Edge ND grads feature a neutral grey effect at the top of the filter that sharply transitions to clear at the centre 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.
Reverse ND grads are specialty filters designed for shooting sunrise and sunset where the highest luminance is near the horizon line. The reverse grad features a hard transition in the centre of the filter (similar to the hard edge grad) but reduce in density toward the top of the filter.
