6.1 Highlight/Shadow/Outside of the Color Gamut Warnings
A warning will be displayed blinking on the picture in preview mode.
(1) Enable Highlight warning
The place where lightness is saturated blinks in black and where the lightness is underexposed blinks in white.
This function is convenient for adjusting exposure.
In addition, since a warning is given for a saturated color in an inversion color (negative), you can use it conveniently when you adjust saturation.
Enable Out of Gamut warning
Refer to '10.7 Creating Color Gamut and Adjusting Outside of the Color Gamut' about the color gamut.
You can set the curve which exchanges lightness while editing a picture. The horizontal axis means input (brightness of source picture) and the vertical axis means output (brightness of result picture after exchange). You can control lightness in a picture by operating this curve.
* By dragging window's frame of the "Tone curve" dialog, you can adjust a size of the dialog.
In addition, by dragging it while pressing the Shift key, you can adjust the size while fixing aspect ratio of it.

"Histogram" displays a brightness distribution on a picture. You can check which part of the picture has what kind of brightness.
The horizontal axis means brightness (0 - 255), and the more it goes to the right side, the more brightness increases. The vertical axis means the number of pixels that corresponds to its brightness.
R, G, and B are displayed in each color on a graph, and the place where these overlap is displayed in additive color mixture.
