Operation Manual

3 Sharpen the image by doing one of the following:
• By default, the Intensity slider is set to 0.5. Drag the Intensity slider to the right to
increase the amount of sharpening applied to the image, and drag the slider back to
the left to reduce the amount of sharpening.
• Click the left or right arrow in the Intensity value slider to adjust the sharpening by 5
percent increments, or drag in the value field.
The left arrow decreases the sharpening effect on the image, and the right arrow
increases it.
• Double-click the number in the Intensity value slider, then enter a value from 0.0 to 1.0
and press Return.
Use the Intensity slider and value
slider to adjust the strength of
the sharpening adjustment.
Use the Radius slider and
value slider to adjust the area
over which the sharpening
adjustment is applied.
A value of 0.0 applies no sharpening adjustment to the image. A value greater than 0.0
increases the sharpening adjustment to the image.
4 Adjust the area over which the sharpening adjustment is applied (the distance, in pixels,
that Aperture goes from each pixel to evaluate sharpness) by doing one of the following:
• By default, the Radius slider is set to 1.0 pixels. Drag the Radius slider to the right to
increase the area over which the sharpening effect is applied, and drag the Radius slider
back to the left to reduce it.
• Click the left or right arrow in the Radius value slider to adjust the Radius pixel distance
by 5 percent increments, or drag in the value field.
• Double-click the number in the Radius value slider, then enter a value from 0.0 to 20.0
and press Return.
A value of 0.0 applies no sharpening adjustment to the image. A value greater than 0.0
increases the area over which the sharpening adjustment is applied.
As you change the parameter values, the image is updated to display the sharpening
effect.
You can also brush the Sharpen adjustment on selected parts of an image. For more
