The Irix Soft nano 1.5 filter is used in conjunction with an IFH-100 support and in case you want another rectangular filter of identical size to achieve unique effects, reducing exposure selectively. In addition, this filter has a very resistant material treated to prevent the appearance of drops that may prevent capture.

The nisi 100x150mm Nano Soft-Edge Graduated IRND 1.5 filter is a rectangular filter that helps darken specific areas of an image, such as bright skies, while allowing normal, unchanged exposure in the other regions of the image. The filter is denser at the edge and tapers to clear in the middle, with a smooth edge transition line between the dense and light areas. A neutral density filter with a smooth-edged transition line is particularly useful for images that do not have a very sharp transition between the sky and the foreground. Neutral density filters do not affect image coloration and this filter provides up to 5 stops reduction in light input to the lens.
The design of this filter has been optimized for use with digital sensors and to promote near-flat attenuation of visible and infrared light. Due to the greater susceptibility of image sensors to infrared light, compared to traditional film, color nuances can occur when photographing darker subjects that require longer exposure times. To provide a high level of neutrality across the visible and infrared spectra to eliminate color tints and ensure cleaner, truer blacks when using the 100 x 150 mm soft-edge nano graduated IRND 1.5 nisi filter, a layer of optical nanocoating nisi is applied to each of the surfaces of this filter. The Nano coating associated with this filter also results in an enhanced pearl effect when in contact with water or oil for greater cleaning efficiency.
