This dialog box controls the parameters used by the Élesítés / Sharpen command (Új kép / New image menu). As you change the parameters, The Panorama Factory shows you the effect interactively within the preview rectangle.
The Élesítés / Sharpen command sharpens images using unsharp masking. This method locates areas of high contrast (edges) and increases the contrast to enhance edge sharpness. This can help correct loss of sharpness introduced by scanning, printing and image sampling.
Mérték / Amount (percent)
The amount of sharpening. 100% is a good starting point. Larger values
produce more a stronger sharpening effect and smaller values produce a more
subtle sharpening effect.
Sugár / Radius (pixels)
The size of the sharpening effect near edges. Larger values are needed for
high resolution images, but larger values can tend to create “halos” at edges.
When images are printed at high resolution, the effect is less noticeable.
Typically, a radius of 1 is appropriate for web display (computer displays are
typically about 72 dpi). For printing high resolution images, 2 or 3 may be a
good starting point. You may need to make test prints to determine the best
value.
Határérték / Threshold (levels)
The amount of difference between neighboring pixels that is needed to trigger
the sharpening effect. Setting a threshold can help avoid increasing noise in
areas of low contrast. A threshold of 5 is a good starting point, but you can
use the preview display to decide what value works best.
