Unsharp masking
Another uncommon feature that appears on the T300 is the ability to apply an unsharp mask to images.
Unsharp Masking
A process by which the apparent detail of an image is increased; generally accomplished by the input scanner or through computer manipulation.
Unsharp Masking - A technique used by scanners and image editors to increase the sharpness of an image.
Unsharp Masking (Unsharp Mask). The process by which the apparent detail and sharpness of an image is increased. Generally accomplished by the input scanner or through computer manipulation using editing software.
Unsharp masking. The process for increasing the contrast between adjacent pixels in an image, thus increasing sharpness, especially around edges.
Upload. Sending a file from your computer to another device.
Unsharp Masking
Often abbreviated USM. Describes an image focusing process. The quality of the result depends on the characteristics of the algorithm used.
Unsharp Masking is a process where by the perceived sharpness of an image is enhanced by increasing the contrast along the edges where different tones meet.

Unsharp Masking
Despite the name it's a process designed to increase visual sharpness. Many cameras will apply some unsharp masking automatically.
One of the downsides to traditional unsharp masking is that the changes are made directly to the image you are working on. I generally prefer making updates on Adjustment Layers, but Unsharp Mask doesn't work that way.
One of the most frequently-used yet most commonly misunderstood post-processing operations has to be "sharpening" -- technically "unsharp masking" or USM for short.
This edge enhancement technique is called unsharp masking and involves isolating the edges in an image, amplifying them, and then adding them back into the image.
Until Photoshop CS2, the best choice (confusing name aside) has been Unsharp Masking. Unsharp Masking is a powerful tool, but thanks to new algorithms and expanded controls, CS2's new Smart Sharpen filter produces even better results.
Capture is a robust tool for professional image enhancement of JPEGs and TIFFs, offering cropping, size and resolution adjustment, unsharp masking, color balance adjustment, batch file conversion, camera custom setting management, ...
USM - Abbreviation for UnSharp Masking, a means of creating additional definition in the edge transition areas of an image in order to retain detail.
If an image looks soft, it can often be improved by sharpening, a process (technically called unsharp masking) that adds contrast along lines and edges.
Sharpening
A post production process that increases contrast and adds apparent clarity or sharpness to a digital image. The most common method is called unsharp masking (USM).

I recommend experimenting with the unsharp masking controls a bit, starting at 100 for Amount, 0.3 for Radius, and 0-3 for Threshold. First, increase the Amount setting, then increase the radius by 1/10 point at time.
mottling
a texturing seen in the smooth or monotone areas of an image. This can be due to faulty processing and a number of improperly used digital processes e.g. excessive unsharp masking.
This produces an increased visual contrast on edge sharpness, thereby enhancing the image. The particular control section of a scanner that carries out this particular function is the unsharp masking area (USM).
True unsharp masking is done by subtracting a blurred version of an image from the original. Unsharp mask routines in software simulate this effect and make it easier to have control over the final image. Uranus Seventh planet from the Sun.
