The Info tab shows information that is not essential but which may be helpful in certain circumstances.
Show Blown Highlights
If the Show Blown Highlights option is checked, highlight areas that were cutoff by LightMachine will be displayed as a line pattern in the image. Additionally activating this check box shows a percent value in the check box label which indicated the percentage of blown highlights. This feature doesn't show blown highlights that were already present in the image before you executed LightMachine.
The B/W check box converts the image to black and white. This can help to see the tones in the image more clearly. It can also be used to create B/W effects.
When moving the mouse over the preview the color under the cursor is displayed in the color box of the Info tab sheet. Additionally the color is shown as RGB and HSL values. The x and y values represent the image coordinates.
The two lines at the bottom of the Info tab sheet show the image size in pixel and the channel bit depth. The second line only appears in the Standalone/Lightroom version and names the color space of the image or shows "No Profile" if no profile was embedded in the image file.
