Kase Magnetic Circular GND0.9 Filter for Mobile

The Kase Reverse-Graduated ND 0.9 Filter can be applied to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image. This filter achieves its effect with a 0.9 band of density above its center region that provides up to a 3-stop reduction in light from entering a lens. This band extends in both vertical directions and tapers to approximately a 0.3 density and a 1-stop reduction in light at the edge above it. Directly below the 0.9 bands of density, it tapers to clear, with a hard-edged line of transition before the clear area..
