Tone Correction Mode Tone Correction mode is used for correction of the brightness of images in the light and dark areas. As a result the overall impression of the image improves considerably. Changes can be made to the entire image or to a part of the image depending on the colors selected for correction.

To process an image in this mode, follow these steps:
- Step 1. Once this mode is selected the processed part of the image appears in the Preview Window in the Before tab.
Preview Window is a box with a boundary composed of a "running" dotted line, which shows the result of image processing based on changes made to the settings (by default in this mode all settings are set to 0, so at first the image in the preview window will be the raw (unprocessed) image). This box can be easily dragged and dropped to another part of the image (click and hold the left mouse button) or redrawn (double click) over any part of the image. In this way you can analyze other parts of the image.
To compare the processed sample with the original photo, left-click on the image within the Preview Window.
- Step 2. You can choose the colors to be corrected. To do this use the
Color Set. The original set consists of seven colors. There are two additional sets below it, each consisting of three cells. You can move colors from the core set into these cells. By dragging colors you can have from one to three sets of colors. To switch from one color set to another click on it with the left mouse button. The chosen color set is highlighted in white.
The Color Indicator makes it easier to form a color set.
From one to three color components are automatically chosen for each point on an image. When you move the cursor over the image, the Color Indicator displays the color components of the corresponding point. The Color Indicator helps select more precisely the color set for editing this area.
- Step 3. Adjust parameter values. The parameters for each color set are regulated separately. The selected set has a white background. Change the parameters for it:
- Radius. This parameter accepts values from 0 to 60 and determines for each point the area to be analyzed by the algorithm. After analysis new color and brightness information is assigned to the point, which is used to assign the point to one of the color sets. Then the point is processed further.
- Shadows. The default value of this parameter is 0 and dark areas are not corrected. As the parameter's value is increased, dark areas become lighter, and details there become more discernible. Objects in dark silhouettes become more like they were when photographed.
- Highlights. By default the value of this parameter is 0 and light areas are not corrected. As the value of the parameter is increased, light areas become darker, contrast increases, and objects stand out more while the picture overall has more volume and appears more accurate.
Note: |
For colors that do not belong to the main set, the application of the parameters is mixed. For example, if the colors red and yellow are in different sets, then correction for the color orange will fall within both color sets. |
- Step 4. To process the image press the
