Nikon NX2 user manual Focus Gaussian Blur, Focus High Pass, Radius

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.
