4. Switch to Noise Filter Settings tab

Click the Noise Filter Settings tab:

6. Adjust filter settings

a) reset the filter settings using the Trash Can buttons (for noise filter and sharpening settings).

b) default filter settings should produce good results but try to vary the settings and see how the preview changes:

Start by varying Noise Reduction Amounts: Luminance channel. This controls how much of the detected noise is removed in the luminance channel of the image. Too high value of the noise reduction amount can lead to unnatural (oversmooth, plastic-like) results. Too low values may be not enough to sufficiently reduce objectionable noise. You have to balance the noise reduction amount in the luminance channel to get the result that looks best to YOUR eyes.

Default values of Noise Levels usually provide good results. If the noise analysis was accurate in step 3 above then you do not have to adjust the Noise Levels settings. You only have to change them if you see that there is any objectionable residual noise or JPEG compression artifacts remaining after applying filter, even if the Noise Reduction Amounts settings are set to remove 100% of the detected noise. In such a case, increase the Noise Levels values to tell Neat Image that there are some residual noise elements remaining in the luminance or chrominance channels.

You can find more details about noise filter settings in the User Guide, the Filtration process details section, the Stage III. Adjust filter settings subsection.

c) when you are happy with the preview results proceed to the next step below.

8. Final result

After the processing is completed, the filtered image is back in Photoshop:

Note: if you move the mouse pointer over the above screenshot, it will temporarily switch to the unfiltered image to show the difference between original and filtered images.
