3. Build a noise profile for the input image using Auto Profile Use Auto Profile to build a new noise profile for the input image: 
Auto Profile will automacally find, select and analyze a flat featureless image area that contains only noise and no important details: 
Visually inspect the selected image area - it should contain NO VISIBLE DETAILS, only noise; otherwise the analysis and subsequent noise reduction may be inaccurate. If the selected area does contain any details, move the selection to a featureless area or simply draw a new selection in such an area (the selection should be more than 60x60 pixels large). Then click the Auto profile button again. After that, a new noise profile is ready and the input image can be processed. |
