Focus > Gaussian Blur

Use the

Gaussian Blur tool to dramatically reduce the

appearance of detail throughout 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.

The

Gaussian Blur tool provides the following controls:

Radius

The

Radius slider controls the intensity of the blur being applied to the image.

Opacity

The

Opacity slider blends the blur effect with the details in the image to provide you with control over the

balance of detail. 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.

Focus > High Pass

The

High Pass tool blocks 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 & Chrominance

mode with the

Opacity (Chrominance Ch.) slider set to

0% and

Blending Mode set to the Overlay option.

The

High Pass tool provides you with the following

controls:

Radius

The

Radius controls the size of the edge to display in the resulting image. Settings for this slider are

dependent on the size of the image, so a radius setting that works well for one image may not be sufficient
for an image with a higher resolution.
