Irix Edge Hard GND8 (0.9) 3EV nano IR 100x150mm Filter

The Irix Edge Hard Graduated ND8 filter with an optical density of 0.9 provides a 3-stop reduction of light compensation with a soft transition from the top of the filter to the center. This filter helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. Hard Graduated Filters are very useful when you are photographing hard line horizons like seascapes or savannas.
