III. Build noise profile using Auto
Profile 1. Click the Auto Profile button
to build a new noise profile for the input image: 
Auto Profile will try to automatically
find and analyze a flat featureless image area
that contains only noise and no important details: 
2. Visually inspect the selected image area - it should contain NO
VISIBLE DETAILS, only noise; otherwise the noise profile 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 32x32 pixels large). Then click the
Auto profile button again.
3. The noise profile is now ready and the input
image can be processed. |
