RADIUS The Radius controls the size of the edge to display in the resulting image. Settings for this slider are dependant 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. Click OK to apply the High Pass feature to your image. The cancel button can be selected to prevent the application of the High Pass feature. Unsharp Mask 153 within your image. Please note: It is recommended that you zoom your image to 100% while determining the amount of sharpening to apply to your image. CHANNEL First select the channel that you wish to sharpen. Additional channels may be selected later, after you have modified the settings for the first channel. By default the RGB option will be selected, which enables you to sharpen all three channels (Red, Green, and Blue) of your image simultaneously. You can choose to sharpen RGB or any individual color channel individually (Red, Green, Blue, Cyan, Magenta, or Yellow). Chapter 22 Adjust Menu The Unsharp Mask feature increases the apparent sharpness of your image by enhancing the edges of objects in your image. Unsharp Mask works by increasing the contrast of edges throughout your image and features controls over Intensity, Radius (halo width), and Threshold. The Unsharp Mask Tool from Capture NX is unique in that it always applies its sharpening to the luminosity of the image, which prevents any unwanted color shifts from occurring INTENSITY You can then select the intensity of the sharpening effect that you want to apply. The higher the sharpening intensity, the more pronounced the sharpening effect will be on your image. If the Intensity setting is set too high it can create an oversharpened and artificial looking image. RADIUS The Radius (halo width) slider enables you to increase the reach of the sharpening effect. The higher the radius setting, the wider the edges in the sharpened image will appear. A radius setting that is too high will produce visible halo artifacts, which can appear as white outlines around the objects.
