Transforming Image Colors
Transforming Colors by Direct Parameter Input
How to Make ‘Direct Input’ Color Trafos
1. Press F12 or select IMAGE | COLOR TRANSFORMATION.
2. Repeatedly select MODE in the MENU window until the TRANSFOR-
MATion mode is active. The current mode is indicated in the STATUS
window.
3. Select DIRECT in the MENU window. The first parameter (R) appears
in the STATUS window.
The default value is 50 for all parameters, unless you have already
replaced colors using function OLD COLOR and NEW COLOR. In this
case the default values already reflect the changes you have made.
4. You can change the value within a range of 0 to 100. Note that values
lower than 25 and higher than 75 will usually not produce usable results.
Do one of the following:
• Enter the new value directly on the keyboard (see page 29-7).
• SHIFT-click on the image, then move the mouse vertically. Click
again when the value you want is reached. The value corresponding
to the cursor position is indicated in the status bar.
The next parameter is selected automatically. The current parameter
is highlighted by boldface type in the STATUS window.
5. Repeat the last step until you have changed all 9 parameters.
6. When finished, press RETURN/ENTER or click .
The following table shows some key values for the first 6 parameters. In
this table A is the color that depends on color B:
50 No change
75 100% of color B is added to color A
58.33 Color A is reduced by 33% and 33% of color B are
added to it
25 Color A is increased by 100% and 100% of color B are
subtracted from it
41.66 Color A is increased by 33% and 33% of color B are
subtracted from it
Note: • It is advisable to first set the gray balance using the Y, M and C
parameters and then specify the other 6 color parameters.
• Switching to another MODE cancels all color transformations made
by ‘direct input’.
