Sharpen

The Sharpen tool improves the clarity of an image by increasing the color contrast between pixels.

To adjust parameters go to the Settings Panel. To change a parameter enter a numerical value in the parameter's field and press Enter (Macintosh: Return) or adjust the slider.

• Diameter (1-500). Sharpen tool size (in pixels).
• Hardness (0-100). The width of the tool's outer edge, where sharpness is partially applied. At higher values the amount of sharpness applied to the inner area of the tool increases.

Hardness = 30%	Hardness = 95%

• Amount (1-250). The amount of contrast between pixels. At a value of 100% contrast is increased 2 times, at 200% by 4 times, etc.

Changing Sharpness By Adjusting Contrast
Amount = 20%	Amount = 210%

• Radius (0.1-20.0). The degree of edge sharpness. This parameter specifies the number of neighboring pixels that are affected by the sharpness of a pixel. When the value is increased, the intensity of transition between colors increases.

Increasing Clarity by Adjusting the Amount of Edge Sharpness
Radius = 3.0	Radius = 18.0

To enhance sharpness along a straight line, select a starting point with the left mouse button, then, while keeping Shift pressed, move the cursor to the end point and release Shift. If Shift is not released, a new line will be drawn each time the mouse is clicked over the image.
