The Pancro 4 x 5.65" ND 0.3 Filter is a solid neutral density filter providing a 1-stop exposure. This 0.3 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.
When calibrated by a spectrophotometer at 2840K, the color temperature of indoor tungsten lighting, this filter experiences a color shift of only 16K towards red.
