Tutorial: AKVIS Noise Buster

How It Works

 

AKVIS Noise Buster reduces both luminance and color noise on images without spoiling other aspects of the photo. The software can work independently as a standalone program and as a plugin to a photo editor.

Follow the instructions below to reduce noise on a picture using AKVIS Noise Buster.

  • Step 1. Open an image.

    - If you work with the standalone edition:

    The dialog box Select File to Open appears if you double-click on the empty workspace of the program or if you click on the button on the Control Panel. You can also drag the required image into the workspace of the program. The program supports images in the JPEG, TIFF, BMP, PNG, and RAW formats (CRW, NEF, ORF, PEF etc - see the full list here). You can also drag the required image into the workspace of the program.

    - If you work with the plugin:

    Open an image in your photo editor by calling the command File -> Open or using the key combination Ctrl+O (or +O on Macintosh).

    Call the AKVIS Noise Buster plug-in. For this purpose call the command Filter –> AKVIS –> Noise Buster in Adobe Photoshop; Effects –> Plugins -> AKVIS –> Noise Buster in Corel Paint Shop Pro; Effects –> AKVIS –> Noise Buster in Corel Photo-Paint.

  • Step 2. Once the program is open, it will begin processing the image using the default settings (the Automatic Filtering preset).

    Auto Filtering automatically chooses the best settings for particular kinds of noise by adjusting 4 noise suppression parameters.

    The result of the filtration will be shown in the Quick Preview area in the Before tab. It is represented by a dotted frame. You can drag the frame or draw it anew on any part of the image, thus analyzing parts of the photo.

    Noise Reduction Quick Preview

    You can compare the filtered result with the original image by clicking in the preview area.

    It's possible to change the size of the quick preview area in the program's Preferences .

  • Step 3. If the result of automatic filtration is not wholly satisfying you can adjust the effect parameters to achieve the best result.

    The task of noise reduction is to find the golden mean between suppressing noise and keeping detail. Besides, it is important to take into account the psychological characteristics of visual perception: when comparing the original and the filtered photo pay your attention not only to details but to the overall impression as well. A certain amount of noise does not necessarily spoil a picture, while some smoothness of a photo may add to the visual effect (especially in portrait retouching where it is not desirable to see the skin structure in detail).

    Adjust the noise reduction parameters
  • Step 4. To process the entire image, press the button . Filtering of the entire image also starts when the After tab is pressed.

    After processing it is possible to switch between Before/After tabs by pressing the left mouse button anywhere in the image window.

  • Step 5. You can also use the post-processing tools in the After tab: Smudge , History Brush and Smart Blur .

    Attention! If you change the parameters and run the image processing again, the changes made with these tools will be lost.

    • The Smudge tool helps to refine the image by removing unwanted irregularities.
    • The History Brush tool restores areas to their original state.
    • The Smart Blur tool smoothes out grain and noise while preserving outlines and fine details. It is available only under Home Deluxe and Business licenses.
  • Step 6. It is possible to save the settings you like as a preset and use them in the future. The presets are also helpful when working in the batch processing mode.

    To save a preset, enter a name for the preset into the Presets field and press the button Save. If you change the values of the parameters, you can always come back to the default settings of the preset by pressing the button Reset.

    To delete a preset, select it from the list and press Delete.

    To process an image with the settings of a certain preset, you should select it from the drop-down menu and press the button .

  • Step 7. You can share your images by clicking on . It lets you publish the picture from the program to the social networks: Twitter, Flickr, Google+, Dropbox.

    In the standalone version you can also print your image with .

  • Step 8. Save the processed image.

    - If you work with the standalone edition:

    Click on the button to open the Save as dialog box. Enter a name for the file, choose the format (TIFF, BMP, JPEG or PNG) and indicate the target folder.

    - If you work with the plugin:

    To apply the result to the image and close the plug-in's window, press the button .

    Call the Save As dialog box using the command File -> Save As, enter a name for the file, choose the format and indicate the target folder.
