Operation Manual

• Double-click the number in the Saturation value slider, then enter a value from 0.0 to
4.0 and press Return.
Use the Saturation slider
and value slider to adjust
the saturation of colors in
the image.
A value below 1.0 decreases the color saturation in the image, and a value above 1.0
increases the saturation. A value of 0.0 removes all color from the image, making it
grayscale. A value of 4.0 increases the saturation by 400 percent.
The saturation of the image is updated as you change the parameter value.
A Little Saturation Goes a Long Way
Increasing the saturation of an image can make the colors appear more pure, and many
people like the effect of an image whose colors are more saturated than they would
appear naturally. However, you can easily oversaturate an image. In the process of
making the colors more pure, subtleties in shades of colors disappear, often resulting
in reduced detail in the image. To ensure that visual elements aren’t unnecessarily lost,
pay attention to the details in your image as you increase saturation.
