Setting Hue Shift, Saturate, and Contrast, Color Balancing with Hue Tint and Strength

Page 666 highlights

24 Color Correcting Setting Hue Shift, Saturate, and Contrast Use the Hue Shift, Saturate, and Contrast fields for fine control over the color you are adjusting. The defaults for these parameters are 0, 100, and 100 respectively. Hue Shift-Changes the colors in the image. Since you are working with a circle, a hue shift value of 360 returns to the original color or image. A hue shift of 180 is equivalent to a negative, as the colors are at their complements. You can use hue shift to compensate for material that is too hot or cool, or simply to correct undesired tones present in the images. Note that in a monochrome or very low saturation image, a hue shift produces no results, since there is no hue to begin with. To apply a hue shift: Do one of the following: • Adjust the Hue Shift field. • Place your mouse on the outer ring of the color wheel and drag in a circular motion. Saturate-Saturation indicates how concentrated the color is: a saturated color has very little gray, while a de-saturated one is "dampened" with more gray. For example, a pastel blue has a very low saturation level, while a blue screen is heavily saturated. A scarlet red has a high saturation, while a pale pink has a low one. To use saturate: Adjust the Saturate field. Contrast-Contrast indicates the difference between the light and dark colors in an image. A high-contrast image is mostly black and white, with very little gray. A low-contrast image is very flat, foggy, and composed mostly of midtones. To use contrast: Adjust the Contrast field. Color Balancing with Hue Tint and Strength The two parameters used with color balancing are tint and strength. The value of tint determines the color to add and the value of strength specifies the amount of color to use. To adjust tint and strength: Do one of the following: • Adjust the Tint and Strength fields. • Click and drag the center of the wheel. The tint and strength values update accordingly. Click and drag again to adjust a different range (shadows, midtones, or highlights) of colors. Pure red is the 0-degree point for hue on the color wheel. When you increase the tint value, you move counter-clockwise on the color wheel. When you use a negative value for tint, you move clockwise on the color wheel. The center of the color wheel represents 0 strength. As you increase the value of strength, you move towards the edge of the color wheel and add more of the selected color to the image. Color Suppression Color suppression suppresses or "dampens" the channel information for one or more channels. It is available for all channels. Note: More color suppression tools are available in the Color Suppression operator. 650

Use the Hue Shift, Saturate, and Contrast fields for
fine control over the color you are adjusting. The
defaults for these parameters are 0, 100, and 100
respectively.
Hue Shift
—Changes the colors in the image. Since
you are working with a circle, a hue shift value of 360
returns to the original color or image. A hue shift of
180 is equivalent to a negative, as the colors are at
their complements.
You can use hue shift to compensate for material that
is too hot or cool, or simply to correct undesired
tones present in the images. Note that in a
monochrome or very low saturation image, a hue
shift produces no results, since there is no hue to
begin with.
To apply a hue shift:
Do one of the following:
Adjust the Hue Shift field.
Place your mouse on the outer ring of the color
wheel and drag in a circular motion.
Saturate
—Saturation indicates how concentrated
the color is: a saturated color has very little gray,
while a de-saturated one is “dampened” with more
gray. For example, a pastel blue has a very low
saturation level, while a blue screen is heavily
saturated. A scarlet red has a high saturation, while a
pale pink has a low one.
To use saturate:
Adjust the Saturate field.
Contrast
—Contrast indicates the difference
between the light and dark colors in an image. A
high-contrast image is mostly black and white, with
very little gray. A low-contrast image is very flat,
foggy, and composed mostly of midtones.
To use contrast:
Adjust the Contrast field.
Color Balancing with Hue Tint and
Strength
The two parameters used with color balancing are
tint and strength. The value of tint determines the
color to add and the value of strength specifies the
amount of color to use.
To adjust tint and strength:
Do one of the following:
Adjust the Tint and Strength fields.
Click and drag the center of the wheel. The tint and
strength values update accordingly. Click and drag
again to adjust a different range (shadows,
midtones, or highlights) of colors.
Pure red is the 0-degree point for hue on the color
wheel. When you increase the tint value, you move
counter-clockwise on the color wheel. When you use
a negative value for tint, you move clockwise on the
color wheel.
The center of the color wheel represents 0 strength.
As you increase the value of strength, you move
towards the edge of the color wheel and add more of
the selected color to the image.
Color Suppression
Color suppression suppresses or “dampens” the
channel information for one or more channels. It is
available for all channels.
Note:
More color suppression tools are available in
the Color Suppression operator.
