Color Noise Suppression
Shooting with a good camera does not necessarily spare you
the trouble with noise. If lighting is insufficient for the sensor you can often see color noise on
your photos. Color (chroma)
noise is perceived as random color dots spoiling the color
accuracy of a snap-shot.
The following photo illustrates color noise.
If we scale up the image we will clearly see color noise. Do you see these color blots on the cat's hair?
Open the photo in a photo editor and call AKVIS Noise Buster.
Let's begin with applying automatic filtration. Press
the button Automatic
Filtering.
The result of the filtration will be shown in the After tab
in the preview area. To evaluate the accuracy of filtering, you
can drag the preview frame to see any other part of the photo processed,
or just draw the preview area anew on any part of the image.
As a result the color noise is completely suppressed.
Now we can also see some luminance noise. It's up to you to decide to reduce
it or not. You can suppress it a little bit by moving the slider of Luminance
Noise Level from 9 to 11 and Luminance Smooth Level from
1 to 2.
To apply the filtration settings to the whole image press
the button  .
Apply the filtration to the image by pressing the button  .
Below there is a fragment of the image: on the left - before
filtration, on the right - after the color noise suppression.
