  • Step 1. Switch to the Local Correction mode . Choose (the hot-key is B) and draw over the image to select areas for additional processing. The tool size is adjustable in a pop-up box which appears after right-clicking on the image.

    You can easily edit or remove selections with the Eraser .

    Selection

    Use / to show/hide all selected areas.

  • Step 2. Right click within the selection to open the parameters for this area. Different areas can be processed with different parameters.
    • Show Selection. Disable the check-box to hide the selection and view the image.
    • Exposure (-100..100). If the exposure is too low, the image becomes dark with the lack of details in shadows, if it's too high - the image lightens up with loss of detail in light areas.

      Exposure = -50 Exposure = 50
      Exposure = -50 Exposure = 50

    • Saturation (-100..100). The parameter changes the color intensity.

      Saturation = -50 Saturation = 50
      Saturation = -50 Saturation = 50

    • Contrast in Shadows (0-200). The parameter makes dark areas even darker.

      Contrast in Shadows = 10 Contrast in Shadows = 100
      Contrast in Shadows = 10 Contrast in Shadows = 100

    • Contrast in Highlights (0-200). The parameter makes light areas even lighter.

      Contrast in Highlights = 50 Contrast in Highlights = 150
      Contrast in Highlights = 50 Contrast in Highlights = 150

    • Temperature (-100..100). The parameter makes the image colder or warmer. Moving the cursor to the left of 0 increases the number of cool (blue) tones, while moving it to the right of 0 increases the number of warm (yellow) tones.

      Temperature = -50 Temperature = 50
      Temperature = -50 Temperature = 50

    • Details (-100..500). Increasing the parameter sharpens the image. If the value is less than 0, the image is blurred.

      Details = 0 Details = 500
      Details = 0 Details = 500

    • Threshold (0-100). The parameter determines pixels to be processed.

      Threshold = 5 Threhold = 50
      Threshold = 5 Threshold = 50

    • Transition (0-100). The parameter creates a smooth transition between adjacent pixels.

      Transition = 30 Transition = 80
      Transition = 30 Transition = 80

    • Radius (0-5000). The parameter lets you increase the processing area spreading the effect beyond the selection.

      Radius = 100 Radius = 1000
      Radius = 100 Radius = 1000

    Any changes of the parameters are applied automatically.
