Digital noise reduction

Digital noise reduction

Digital Noise Reduction or DNR is a software program used to enhance the quality of digital photographic reproductions of either still or moving images. It is a tool especially useful to correct imperfections (such as film grain, electronic noise, film speckles, dirt, scratches, etc) inherent in the source material, in particular those from film negatives, photographs and other such copies.
