Hoya Filters HD SQ100 IRND16 GRAD-S (0-4 Stop) clearsky Filter Factor: 1 2/3 stopsOVERVIEW In landscape photography, where the scenery and horizon tend to have complex or uneven structures, gradated ND filters become absolutely essential, as they allow the photographer to balance the luminosity of bright areas with the dark areas in the image. With HOYA's Sq100 IRND16 (1. 2) GRAD S filter, the photographer has new options in using a GRAD filter which they do not have with round type filters. Photographer: Andrew Leggett TECHNOLOGY
