Best noise reduction
for digital cameras and scanners

Quick Start Guide — Standalone

This guide is for Neat Image v8 standalone. If you use another version of Neat Image, please check its documentation.

I. Start Neat Image

The main window of Neat Image will open up:

II. Open an input image in Neat Image

Use the Open input image button:

III. Switch to Device Noise Profile

Click the Device Noise Profile tab:

IV. Build a 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 must be at least 32x32 pixels large). Then click the Auto Profile button again.

3. After that, a new noise profile is ready and the input image can be processed.

V. Switch to Noise Filter Settings

Click the Noise Filter Settings tab:

VI. Check Preview

Neat Image will automatically select an area or the whole visible part of the image and prepare a preview:

Hint: click in the preview area in Neat Image to compare before and after versions.

VII. Adjust Filter Settings to tune noise reduction and sharpening

  1. The default filter settings should produce good results, yet it may be useful to change some settings and check the preview:

    1. Try to vary Noise Reduction Amounts: Luminance.
      This controls how much of the detected noise is removed in the luminance component of the image. Too high values can lead to unnatural (oversmooth, plastic-like) results. Too low values may be not enough to sufficiently reduce objectionable noise. You can balance the noise reduction amount to get the result that looks best to your eyes.
    2. Try to change other parameters as well.
    3. You can find more details about noise filter settings in the Filtration process details section of the User Guide.

2. When you are happy with the preview results proceed to the next step below.

VIII. Switch to Output Image tab to process the whole image

Click the Output Image tab:

This will automatically process the whole input image.

IX. Save output image

After the processing is completed, save the output image:

The above steps explain the basic Neat Image workflow. There is a lot more information about building noise profiles, adjusting filter settings, using the calibration target, etc.
