In landscape photography, where the landscape and horizon tend to complex or uneven structures, graduated ND filters are indispensable as they allow the photographer to balance the brightness of the bright areas with the dark areas in the image. The Sq100 IRND16 (1.2) GRAD-S filter from HOYA opens up new possibilities for photographers using a GRAD filter that are not available with round filters. The HD Sq100 GRAD-S series, made from hardened glass, is designed to withstand the harsh conditions of travel and adventure. The IRND nanocoating on both sides of the clear optical filter glass not only removes IR contamination but also creates a truly neutral color balance through the applied ACCU-ND technology. This prevents any noticeable color cast in your images. Additionally, the water-repellent and anti-reflective coating minimizes the risk of accidental light reflections while increasing light transmission.
