Chapter 22 152 the image. Moving the slider to the left causes all colors throughout the image to become cooler, or bluer. Moving the slider to the right will warm all of the colors within the image to contain more red-orange. Once you are satisfied with the results of the Saturation / Warmth feature, click on the OK button. Simply click on the Cancel button to prevent this feature from affecting your image. Focus Gaussian Blur RADIUS The Radius slider controls the intensity of the blur being applied to the image. OPACITY The Opacity slider blends the Gaussian blur with the details in the image to provide you control over the balance of detail and the blur effect. Combining a high radius with a low opacity creates a hazy, soft-focus effect, while combining a low radius with a medium opacity produces a dream-like mood. Simply click OK to accept the Gaussian Blur effect, or click cancel to prevent this enhancement from affecting your image. High Pass Adjust Menu Use the Gaussian Blur enhancement to dramatically reduce the appearance of detail through the image. This enhancement is often used selectively to reduce the visual impact of objects or areas within an image in order to draw the viewer's eye away from that object or area. Alternatively, you can use it to add a smoothing effect, such as on skin tones, by adjusting the Opacity Slider within this enhancement. Use the Radius and Opacity sliders to control the result of the Gaussian Blur enhancement. The High Pass feature attempts to block all image details, apart from those details that contain very strong edge definitions. This results in a neutral gray image with only the edges of the original image appearing. This enhancement is often used with the Opacity Mixer set to Luminance and Chrominance mode, with only the Opacity (Chrominance) set to 0% and the Blending Mode set to Overlay. Using the High Pass feature in this way can enable you to control the contrast of objects, or increase the apparent level of detail, depending on the Radius slider setting.

Focus
Gaussian Blur
Use the Gaussian Blur enhancement to
dramatically reduce the appearance of
detail through the image. This enhance-
ment is often used selectively to reduce
the visual impact of objects or areas
within an image in order to draw the
viewer’s eye away from that object or
area. Alternatively, you can use it to
add a smoothing effect, such as on skin
tones, by adjusting the Opacity Slider
within this enhancement.
Use the Radius and Opacity sliders to
control the result of the Gaussian Blur
enhancement.
RADIUS
The Radius slider controls the intensity
of the blur being applied to the image.
OPACITY
The Opacity slider blends the Gaussian
blur with the details in the image to
provide you control over the balance of
detail and the blur effect. Combining a
high radius with a low opacity creates
a hazy, soft-focus effect, while combin-
ing a low radius with a medium opacity
produces a dream-like mood.
Simply click OK to accept the Gaussian
Blur effect, or click cancel to prevent
this enhancement from affecting your
image.
High Pass
The High Pass feature attempts to block
all image details, apart from those
details that contain very strong edge
definitions. This results in a neutral gray
image with only the edges of the origi-
nal image appearing. This enhancement
is often used with the Opacity Mixer set
to Luminance and Chrominance mode,
with only the Opacity (Chrominance)
set to 0% and the Blending Mode set
to Overlay. Using the High Pass feature
in this way can enable you to control
the contrast of objects, or increase the
apparent level of detail, depending on
the Radius slider setting.
