Input Level Histogram

*For example, if you use the input Highlight slider and input shadow slider to remove areas which contain no pixels (flat line at left or right) the original colour will be better represented.

Although the output slider does not normally need to be adjusted, use it according to the characteristics of the output equipment. For example, use the output slider when the black part is not printed clearly with the 0 setting in the black level. (In this case, adjust the Output level by moving the Output Shadow slider to the right slightly while checking the correction result).
