Case of using automatic profiling

To analyze noise properties, Neat Image uses uniform image areas that contain noise but no visible or important details. With automatic profiling, Neat Image tries to find one such area automatically and then uses the found area to analyze image noise.

• Click (the Auto Profile with Regular Image button) on the toolbar, or select the Profile | Auto Profile with Regular Image menu item, or press F2.
  
  Neat Image will show the image area selected for analysis (see blue selection box in the image viewer; blue color is an indication of automatic selection) and will analyze it automatically.
  
  In some difficult cases, Neat Image may have trouble with finding a uniform featureless area in the image. You will notice that the selected area, for example, will contain some important image details. In such a case, just move the selection (or draw a new one) to an area that does not contain any image details and click the same Auto Profile with Regular Image button again.

If you see that the area selected for analysis is indeed uniform and featureless, then you can be sure that noise analysis is accurate. Please simply proceed to Étape II. Documenting the noise profile.
