The Ice 67mm Slim IRND64 Filter is an ND filter with a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 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 are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible light 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.
Mounted within a slim, aluminum alloy filter ring that helps prevent vignetting while remaining durable and lightweight, this filter is constructed from optical glass for clarity and color fidelity. Each glass surface includes six layers of anti-reflection coatings to prevent internal ghosting and reflections.
