Densitometer window

The Densitometer window displays RGB, LCH, and CMYK values for any point in the feedback

window on which you place the cursor.

• LCH is a device-independent color format that is used as a global reference. If you are not a

color repro professional, you may find LCH more intuitive to work with than CMYK or RGB.

For more information on this, see The L

CH color model.

• The densitometer’s CMYK values are based on the CMYK pr

oﬁle chosen in the Scan Setup win-

dow,and its RGB values are based on the RGB Pr

oﬁle chosen. Therefore, it is important to choose

the relevant CMYK Proﬁle or RGB Proﬁle before making any color changes.

• When a color tool

is open (except Introduce Cast, CMYK Curves and Burn Out Background), you

can type the desired output values directly into the Densitometer window. Values can be

entered as LCH, RGB, or CMYK.

• To type in values, first click on the relevant part of the image in the feedback windo

w. Then

type the desired values into the Edit fields in the Densitometer window and click on the check

mark to apply them to the scan.

• As long as you have not clicked on the check mark, clicking on the X will cancel the changes.

Otherwise, delete the change from the image’s Corr

ection History by clicking on the relevant

entry and then pressing Command-X (Macintosh) or the Delete key (PC).

• You can also cancel changes by choosing Revert to Original from the Color menu or tool bar.

However, note that this will cancel all the color changes that have been made to the image.
