Noise

The Noise menu allows to add or remove graininess in your image. It contains the following effects:

 

Add Noise. The filter adds noise to an image.

 

Median. The filter reduces noise in an image by averaging the color values of similar pixels within a predetermined radius.

 

Dust & Scratches. The filter reduces noise by blurring dissimilar pixels within the specified radius.

 

If the Fixed Preview Area check-box is enabled, all changes will be displayed in a small preview area. If the check-box is disabled, the changes will be applied to the area visible in the Image Window.

Click Default to restore the original settings.

Click OK to apply the changes and close the effect dialog box.

Click Cancel to close the dialog box without applying changes.
