This 150 x 150mm ProGlass IRND 1.8 Filter is constructed from scratch-resistant, optical glass for clarity as well as color fidelity and features a built-in gasket. This gasket works with a compatible LEE Filters SW150-series filter holder with an integrated or add-on Lightshield to help form a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in between the filter and the lens behind it. For efficient use in the field, an exposure guide is included that shows the amount of exposure reduction the 150 x 150mm ProGlass IRND 1.8 Filter provides, corresponding to a range of shutter speed settings from 1/1,000th of a second to 2 seconds before the filter is applied.
