How to sharpen image
Sharpening image with Photoshop is a very common and useful task. If your image appears soft or blurry, you can bring back detail, clarity, and contrast with sharpening. Sharpening brings out additional detail in virtually all images except those created on the highest quality scanners. The best way to add overall sharpness to an image is to use the unsharpe mask filter. Be careful not to over-sharpen, which result in an unnatural halo around the objects in the image. Flattening the space. If this occurs, choose EDIT, Undo and reapply the effect.
Begin
1. select the unsharp mask filter
With the image open, choose Filter, sharpen, unsharpen mask. The unsharp mask dialog box opens.
2. Set the amount Slider
Enable the preview check box and set the thumbnail magnification view to 100 by clicking the + or – buttons. The Amount slider control the degree of sharpening applied to the image. Adjust the slider as needed, noting the changes in the preview window in the dialog box.
3. Set the radius slider
The Radius control determines whether the effect is applied to a single pixel or to a group of pixel. A higher radius value lower image detail in exchange for higher overall contrast. For the most naturalistic images, begin by setting this option at 1 and don’t let it rise above 3.
4. set the Threshold slider
The Threshold settings exclude a portion of the tonal range from receiving the effect. Leave it at 0 to apply the effect globally. Move it higher to exclude tone from dark to light. For all practical purposes, you don’t typically change this setting.
Choose Edit, Fade, unshape mask. After the fade dialog box opens, move the Opacity slider to the left to gradually decrease the sharpen effect as necessary. If decide to soften the effect, set the slider accordingly and click OK, leaving the Mode setting atNormal
5. Apply the effect
To zoom in on the image window, select view; zoom in as many times as needed. If the image is larger than the image window, you can use the scrollbar to scroll the different areas in the image. Check the image carefully to ensure that all areas are sharpened to the proper level. When you are satisfied with the image, click on ok to apply the effect.
6. Fade the result as necessary
Choose Edit, Fade, unshape mask. After the fade dialog box opens, move the Opacity slider to the left to gradually decrease the sharpen effect as necessary. If decide to soften the effect, set the slider accordingly and click OK, leaving the Mode setting at
