After two years of development, Lee Filters has released a new series of neutral density filters, ProGlass IRND. The company states that the filters have "virtually no color shift" and "extremely accurate stop values." The filters block both infrared and ultraviolet pollution.
The ProGlass IRND filters are made from two millimeters thick glass and are available in the following strengths: 2 stops (0.6ND), 3 stops (0.9ND), 4 stops (1.2ND), 6 stops (1.8ND), 10 stops (3.0ND) and 15 stops (4.5ND). The ProGlass IRND range is available in 75 x 90mm, 100 x 100mm and 150 x 150mm, meaning that they are designed to fit Lee's Sev5n, 100mm and SW150 filter systems respectively.
Further, the company has released a new app, ProGlass IRND, for Android and iOS which makes it easy for users to quickly and easily calculate a precise exposure when using the new filters. Landscape photographer Jeremy Walker said of the new filters, "I have been very impressed with the new LEE ProGlass IRND filters. They have a very accurate color rendition…the evenness of the exposure across the filter…is superb." For more information about the filters, click here. You can order the new filters here.
