_ tool reduces the sharpness of an image.
Answers
Step by step explanation :
● Zoom the document window to 100% to get an accurate view of the sharpening.Choose Filter > Sharpen > Smart Sharpen.
● Set the controls in the Sharpen tabs:
=>Amount
Sets the amount of sharpening. A higher value increases the contrast between edge pixels, giving the appearance of greater sharpness.
=> Radius
Determines the number of pixels surrounding the edge pixels affected by the sharpening. The greater the radius value, the wider the edge effects and the more obvious the sharpening.
=>Reduce Noise
(Photoshop only) Reduce unwanted noise while keeping important edges unaffected.
=> Remove
Sets the sharpening algorithm used to sharpen the image.
• Gaussian Blur is the method used by the Unsharp Mask filter.
• Lens Blur detects the edges and detail in an image, and provides finer sharpening of detail and reduced sharpening halos.
• Motion Blur attempts to reduce the effects of blur due to camera or subject movement. Set the Angle control if you choose Motion Blur.
=> Angle
Sets the direction of motion for the Motion Blur option of the Remove control.
=> More Accurate
(CS6 only) Processes the file slowly for a more accurate removal of blurring.
● Adjust sharpening of dark and light areas using in the Shadow and Highlight tabs. (Click the Advanced button to display the tabs). If the dark or light sharpening halos appear too strong you can reduce them with these controls, which are only available for 8‑bits and 16‑bits-per-channel images:
=> Fade Amount
Adjusts the amount of sharpening in the highlights or shadows.
=> Tonal Width
Controls the range of tones in the shadows or highlights that are modified. Move the slider to the left or right to decrease or increase the Tonal Width value. Smaller values restrict the adjustments to only the darker regions for shadow correction and only the lighter regions for highlight correction.
=> Radius
Controls the size of the area around each pixel that is used to determine whether a pixel is in the shadows or highlights. Moving the slider to the left specifies a smaller area, and moving it to the right specifies a larger area.
