\nIt\u2019s challenging to reduce the luminance (light and dark) component of noise without compromising image sharpness; often it requires a careful application of specialized software.<\/p>\n

However, you can easily reduce the color component of noise using Photoshop.<\/p>\n

Here\u2019s how.<\/p>\n

1\u00a0\u00a0 \u00a0Duplicate the Background layer and turn the duplicate layer\u2019s blend mode to Color.<\/p>\n

2\u00a0\u00a0 \u00a0Blur the layer (Filter: Blur: Gaussian Blur).<\/p>\n

\"\"<\/a><\/p>\n

Be careful not to use the blur filter too aggressively. If contours exhibit reduced saturation, use a lower filtration
\nUsing this technique, only the color of an image will be blurred, not its luminance; image sharpness will not be compromised. Luminance noise will persist; other methods are required to remove it.<\/p>\n

This industrial strength technique is most useful when dealing with serious color noise when a Raw converter’s features can’t go far enough, such as the larger areas of color noise found in some images from Bayer pattern demosaicing.<\/p>\n
