NiSi Explorer Soft-Edge Graduated IRND Filter (100 x 150mm, 3-Stop)

How to Use ND Filters: An Introduction Read More

This NiSi Explorer Soft-Edge Graduated IRND Filter is compatible with 100 x 150mm filter holders that can accommodate 2mm thick filters. It 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. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is able to filter the sky while minimizing its effect on the land. It is particularly useful where the transition between sky and foreground is indeterminate, such as images featuring mist, fog, or the tops of trees. Neutral density filters do not affect the coloration of the image, and this filter provides up to a 3-stop reduction in light from entering a lens.

NiSi Explorer filters are constructed from tempered, Schott B270 glass for shock resistance as well as increased optical clarity and color fidelity. The design of this filter has also been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums to eliminate color casts and ensure cleaner, truer blacks when using the 100 x 150mm Explorer Soft-Edge Graduated IRND 0.9 Filter, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces. The nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

A padded nylon pouch is included for storage and transport.
