 The only way to be sure which settings of <guilabel>Amount</guilabel>, \
<guilabel>Feather</guilabel>, and <guilabel>Radius</guilabel> best compensate for the \
actual optical characteristics of a given lens is to expose a uniformly illuminated \
scene (for example, a grey card lit by diffuse light) and perform densitometry on the \
resulting image (for example with Adjust Level tool histogram position bar). Failing \
that, or specifications by the lens manufacturer giving the precise degree of \
vignetting at one or more working apertures, you may have to experiment with \
different settings to find those which work best for each of your lenses. For help \
you in this task, the widget dialog provide a thumbnail mask rendering applied on the \
image. Fortunately, the response of the human eye is logarithmic, not linear like \
most digital imaging sensors, so you needn't precisely compensate for the actual \
vignetting to create images which viewers will perceive as uniformly illuminated.  \

these options moves respectively the center of the filter horizontally or vertically \
up to the the border of the image by the specified percentage. A negative value for \
the X offset will shift the filter to the left while a positive value will shift it \
to the right. A negative value for the Y offset will move the filter up, and finally \
a positive value will move it down. +        <guilabel>X offset</guilabel> and \

         <guilabel>Brightness</guilabel>, <guilabel>Contrast</guilabel>, and \
<guilabel>Gamma</guilabel> settings: processing an image with this antivignetting \
tool reduces the luminosity of pixels. You need to re-adjust the target image \
exposure with these options. These sliders give only positive values because you need \
only to increase this setting.
