Smarter sharpening
It is called Adjust Sharpness and can be found in the Enhance menu. In many ways, it resembles the Smart Sharpen filter of newer Photoshop versions, but it doesn’t allow setting the strength of light or dark edges. So, it is not that smart. Still, it offers the basic sharpening options.
Amount specifies the extent of sharpening between 0 and 500%. Radius tells how far the sharpening will go from the edges. Lower values allow only the sharpening of the finest details, while higher ones produce a coarse, rough effect.
The real power of the feature, however, is in the rest of the options.Remove offers three options to specify what kind of blur you want to remove:
Gaussian Blur: Traditional sharpening. Suitable for average or large photos. Its effect is similar to that of Unsharp Mask. Can deal with tiny details, but is really appropriate for sharpening the whole of the picture.
Lens Blur: This option is for countering the fine softness of a lens. By very low values (a radius of 0.1 to 0.2 pixels), it is capable of sharpening the finest details, particularly when used together with the More Refined check box. It can come handy when saving small images for web.
Motion Blur: A rough sharpening feature for correcting motion blur. Severe blur effects cannot be corrected with it. Selecting the options enables Angle, specifying the direction of the motion. Sharpening “compacts” the picture in this direction. Its effect will be demonstrated in the next section.
More Refined: Select it to enable the sharpening of smaller details. Keep in mind that noise in the pictures is usually detected as “finer details”, so the feature can significantly increase noise level. It is perfect for images used on a monitor or the web. |
