In the lower right corner of the window is a cluster of items:
The Preview checkbox is used to control whether the preview image is displayed before or after color correction, as described on the previous page.
Clicking the Undo button will undo the last correction that was made, whether it resulted from clicking a checkbox, clicking a button, or sampling a pixel for memory color correction.
Clicking the Prev button will set all color correction parameters (including any custom memory color definitions) to the values that were used on the previous image.
Clicking the Custom button will set all color correction parameters (including any custom memory color definitions) to the values that were loaded with the Load Custom Settings... button in the Preferences window. If custom settings have not been loaded yet, a window will appear asking you to identify a custom settings file to use.
Shortcut Tip:You can load custom settings and immediately apply them by holding down the key while clicking the Custom button. This is equivalent to opening the Preferences window, clicking the Load Custom Settings button, selecting a custom settings file, clicking OK to return to the main iCorrect Portrait window, and then clicking the Custom button.
You can save the current color correction parameters in a custom settings file at any time, using the Save Custom Settings... button.
Clicking the Reset button will set all color correction parameters to values that effectively turn the color correction off completely. Note that unlike the Prev and Custom buttons, the Reset button does not change the current memory color definitions.
Clicking the Preferences... button will open the Preferences window.
Check the Sharpen checkbox to apply unsharp masking to the image. Check the Remove Noise checkbox to apply an adaptive noise removal filter to the image. Click the Setup... button to open the Sharpen / Remove Noise setup window (the button is disabled if neither checkbox is checked), from which you can set parameters that control the strength of these effects. Although they are not color correction tools, it can be helpful to apply sharpening and noise removal in combination with color correction, such as in a case where noise in an image is exaggerated by a color transformation.
Note that Reset does not affect sharpening and noise removal. If you typically sharpen your images, you can turn sharpening on and it will stay on until you explicity turn it off by unchecking the checkbox, or by loading previous or custom settings in which sharpening was disabled.
If you click Cancel, the iCorrect Portrait window will close, leaving the image unmodified.
If you click OK, the iCorrect Portrait window will close, and the color correction will be applied to the image.
