Zoom Blur dialog box
Span Sets the depth, (length) of the zoom effect. Type a number from 1 to
100 or drag the slider to set the value. A larger number simulates a
greater zoom depth and a more blurred effect.
Zoom In/Out Establishes the direction of the blur effect toward or away from the
viewer. Type a number from -100 to 100 or drag the slider to set the
value. Negative numbers make the image appear to move closer; positive
numbers make the image appear to move away.
Smoothness Controls the quality of the transition of the blur effect. Type a number
from 1 to 10 or drag the slider to set the value. A smaller number creates
a smoother blur with fine color blending.
Centering options These options let you set the zoom origin. Center In Image sets the
origin at the center of the image. Center in Selection sets the origin at
the center of a selection. “Offset from Center in Pixels” lets you type
values to offset the origin from the center of the image or selection. Type
vertical and horizontal offset amounts in pixels in the text boxes.
Negative horizontal offsets move the center to the left. Negative vertical
offsets move the center up. Positive horizontal offsets move the center to
the right. Positive vertical offsets move the center down.
Preview Displays the effect of the current settings.
Sharpen filters
Sharpen filters increase the contrast between adjacent pixels, which can make an image appear more
distinct. These commands work with all image modes except Black & White, Indexed, and Duotone.
Although the Sharpen and Blur filters have opposite effects, they do not negate each other.
To reverse the effects of a Sharpen filter, choose Edit | Undo.
Sharpen filter: Modifies an image slightly. The effect of the Sharpen More filter is about
four times greater.
Sharpen Edges filter: Affects only high-contrast areas.
Unsharp Mask filter: Provides additional control over the sharpening effect.
