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 center of the filter (similar to the hard edge grad) but reduce in density toward the top of the filter. Formatt-Hitech filters are made from the highest quality 1.5mm optical resin.
Graduated Neutral Density
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. Color grads are also available.
Formatt-Hitech offers four varieties of Graduated Neutral Density Filters:
The reverse grad is a vital tool if you are looking to take sunrise or sunset shots. The reverse grad is lightest at the top and increases in density toward the center, then features a hard edge transition to clear at the center of the filter.
This speciality filter is especially useful just after the sun has set where a bright band of light is at the horizon fading to dark at the top of the frame.
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.
