Refocus Mode

 

Use Refocus mode to improve sharpness of blurred images. It lets you re-focus the entire image or bring only certain elements of the image into focus.

Follow the steps below to improve the focus of your image using Refocus mode:

  • Step 1. The photo will be processed with the default parameter values (the AKVIS Default preset) and the result will be immediately shown in the quick preview window.

    You can drag the preview area to analyze the effect on the different parts of the photo. Click within the preview to compare the processed sample with the original image. It can be switched on/off with the button . Change the size of the preview in Preferences .

  • Step 2. Adjust the settings to achieve the best result.

    Choose the refocusing settings:

    Smoothing (1-10). The parameter sets the level of smoothness. The higher its value, the stronger the influence of the other parameters is.

    Smoothing = 1 Smoothing = 10
    Smoothing = 1 Smoothing = 10

    Color Blur (1-10). The parameter is used for alignment of colors to a uniform state that lets removing fringing and halos. It is especially effective in tandem with the previous parameter.

    Color Blur = 1 Color Blur = 10
    Color Blur = 1 Color Blur = 10

    Level of Detail (0-50). The parameter strengthens details on an image. Note that at higher values it can produce noise.

    Level of Detail = 0 Level of Detail = 50
    Level of Detail = 0 Level of Detail = 50

    Sharpness (0-50). The parameter changes intensity of the refocusing effect.

    Sharpness  = 0 Sharpness  = 50
    Sharpness = 0 Sharpness = 50

    Remove Noise. This option lets reducing the side effects which can appear on the image (digital noise, grain, artifacts).

  • Step 3. You can process only certain areas using the tools and .

    Note that this feature is only available for Home Deluxe and Business licenses.

    Define the effect area
    • Focus Area . Use the blue pencil to select areas to be processed with the above mentioned settings.
    • Background Area . Use the red pencil to outline parts that will remain in their original state or will be blurred.

      Adjust Background Defocus -> Blur (0-1000). The areas marked with red will be blurred. This option will help you achieve the realistic selective focus effect.

      Without Blur Blur Background
      Blur = 0 Blur = 80

    • Eraser . Use the tool to erase the red and blue strokes. The tool works in three modes:

      - erase all strokes;
      - erase only red strokes;
      - erase only blue strokes;

    Hints: 

    It is better to draw a closed outline around the objects. Otherwise the effect can extend over the drawn borders.

    You can adjust the Size of the tools in a pop-up window that appears after right clicking in the image.

  • Step 4. Click to start image processing. You can interrupt the process by clicking on the Cancel button right to the progress bar.

    Using Refocus Mode
  • Step 5. If you like the new settings you can save them as a Preset and use them later. Enter a name for your new preset and press the button Save.

    Note that the presets save only the parameters values in the Settings Panel, and do not save the areas selected with the tools.
