Use the Noise Filter Settings tab in the Filtration Job Editor:
The noise and sharpening filters have several settings that you can adjust. Default noise filter settings are based on the noise analysis provided by the noise profile; these settings usually produce good filtration results if the noise profile is accurate. You may want to additionally vary the filter settings to achieve the filtration results that look best to your eyes.
There are two sets of filter controls available in the Standard mode and Advanced mode (you can select the mode using the Tools | Standard mode and Advanced Mode menu items). The Standard mode provides a simple control set, recommended for beginners who just start using Neat Image. The Advanced mode provides the most complete control set with maximum manual control over noise profiling and filtration processes. The Advanced mode is recommended for power users. Adjusting filter settings is described below separately for the Standard and Advanced mode. We recommend to start with the part about the Standard mode and then proceed to the part about the Advanced mode if you are going to use the complete control set.
