LEE Filters 100 x 100mm ProGlass IRND 0.9 Filter (3-Stop)

The 100 x 100mm ProGlass IRND 0.9 Filter from LEE Filters is an ND filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. Neutral density filters are intended to not affect the colouration of the image and are ideal for pairing with other filters.

The design of this filter has been optimised 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, colour casts can occur when photographing darker subjects that require increased exposure times.

This 100 x 100mm ProGlass IRND 0.9 Filter constructed from scratch-resistant, optical glass for increased clarity as well as colour fidelity.
