Absorptive Neutral Density (ND) Filter
Overview:
Absorptive Neutral Density (ND) filters is a type of dark filters that easily attaches to the front of a camera lens, to control how much light enters the camera’s sensor. Since a neutral density filter only affects light levels, it doesn’t have any impact on image colour, contrast or sharpness.
Essentially, it’s like a volume control for light. By reducing the amount of light that comes through your camera lens, a neutral density filter lets you shoot in harsh lighting conditions and manipulate your photos to achieve really creative results.
The Absorptive neutral density (ND) filters can be used with both monochromatic and color cameras.
