There is a lot of discussion about how best to remove noise in digital camera images and a lot of tools to do it. For this article I have compared just about every tool possible to try and find the best one. CCD noise comes in two parts, luminance noise and chroma noise. Luminance noise makes an image look grainy on screen, but is usually not visible when printed. Chroma noise is visible as random red and blue pixels and is usually less obvious both on screen and printed. Removing luminance noise reduces the sharpness of the image and removing the chroma noise damages some of the correct color.
