TONE CURVES AND HISTOGRAM

CORRECTING THE HISTOGRAM

The input slide bar has the Input shadow slider, Input gamma
slider and Input Highlight slider. The output slide bar has the
Output Highlight slider and Output shadow slider.
The image can be corrected by dragging the slider or inputting
the value in the text box.
The change will reflect the prescan image.

1.

Drag the slider to move it to the desired level or
input the value in the text box.

• The change will be reflected in the prescan

image.

* 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).
