Formatt Hitech 4x6" 1.5mm 0.9 Neutral Density Grad 3 Stops Soft Edge Filter

Soft Edge ND grads feature a neutral gray effect at the top of the filter that gradually 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 soft edge grad is the most popular and most versatile grad Formatt-Hitech makes because it's easy to blend the gradual transition into an undulating horizon. 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. Grads are also available in a variety of colors. Soft Edge Grads Soft Edge graduated filters transition across the filter toward the center, and although there is a horizon line, it is subtle. This allows for horizon transitions to be more easily hidden in a scene, especially with an undulating horizon line such as mountains, buildings or trees. The Soft Edge grad is the ideal tool for balancing bright sky to a dark terrain where the horizon is uneven. Soft Edge grads are essential for both fine art photographers and professional cinematographers alike, and are the most popular grads Formatt-Hitech makes. Formatt-Hitech Resin 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 Formatt-Hitech's exclusive Absorbing Cell Technology process.
