To modify the range of an adjustment slider (Photoshop):
1
Choose an individual color from the Edit menu in the dialog box.
2
Do any of the following to the adjustment slider:
•
Drag one of the white triangles to adjust the amount of color fall-off without affecting
the range.
•
Drag the area between the triangle and the vertical bar to adjust the range without
affecting the amount of fall-off.
•
Drag the center area to move the entire adjustment slider, selecting a different
color area.
•
Drag one of the vertical white bars next to the dark gray area to adjust the range of the
color component. Increasing the range decreases the fall-off, and vice versa.
•
Ctrl-drag (Windows) or Command-drag (Mac OS) the color bar so that a different color
is in the center of the bar.
Hue/Saturation adjustment slider:
A.
Adjusts fall-off without affecting range
B.
Adjusts range without affecting fall-off
C.
Moves entire
slider
D.
Adjusts range of color component
If you modify the adjustment slider so that it falls into a different color range, the name
changes to reflect this. For example, if you choose Yellow and alter its range so that it falls
in the red part of the color bar, the name changes to Red 2. You can convert up to six of the
individual color ranges to varieties of the same color range (for example, Red through
Red 6).
Note:
By default, the range of color selected when you choose a color component is 30°
wide, with 30° of fall-off on either side. Setting the fall-off too low can produce banding in
the image.
3
To edit the range by choosing colors from the image, select the eyedropper tool
in
the dialog box and click in the image. Use the eyed tool to add to the range; use
the eyedropper – tool to subtract from the range.
While the eyedropper tool is selected, you can also press Shift to add to the range or Alt
(Windows) or Option (Mac OS) to subtract from it.
To colorize a grayscale image or create a monotone effect:
1
(Photoshop) If you are colorizing a grayscale image, choose Image > Mode > RGB Color
to convert the image to RGB.
2
Open the Hue/Saturation dialog box. (See
“Making color adjustments” on page 132
.)
3
Select Colorize. The image is converted to the hue of the current foreground color, if the
foreground color is not black or white. The lightness value of each pixel does not change.
4
Use the Hue slider to select a new color if desired. Use the Saturation and Lightness
sliders to adjust the saturation and lightness of the pixels.
