Black Ref. and White Ref.
Black Ref. and White Ref. work together.
Purpose Sets the range between the darkest and lightest reference
points in the image.
Range Black Ref.—0.000 (less black) to 0.400 (more black)
White Ref.—0.600 (more white) to 1.000 (less white)
Default Black Ref.—0.000
White Ref.—1.000
Notes Increasing the value of the black reference point and
decreasing the value of the white reference point increases the
contrast but narrows the range of midtones.
Illuminant
This option is grayed out to indicate that it is not available on mono-
chrome printers.
Input RGB Gamma
The Red, Green, and Blue input gamma corrections work either inde-
pendently or together.
Purpose Corrects for unbalanced brightness of the input image by
adjusting input gamma.
Choices Selected (checked) or unselected (unchecked)
Defaults Unselected
Range 0.250 (less brightness) to 6.500 (more brightness)
Default 1.000
Notes Red, Green, and Blue check boxes—If the check boxes are
all left unselected, the Red, Green, and Blue scroll bars will
adjust independently. If any two check boxes are selected, the
corresponding scroll bars adjust together. If all three check
boxes are selected, all three scroll bars adjust together.
Linear=1.0 check box—Selecting this check box disables the
Red, Green, and Blue scroll boxes and sets each input RGB
gamma correction to 1.000 (brightness equal to input value).
