CHAPTER 8. TOOLS 58
• Conical (asymmetric): Creates a gradient similar in detail to the Conical
(symmetric) one, but the gradient is not reversed at the half-way point.
• Shapeburst (angular): Maps the layer or selection shape prior to rendering
the gradient. The resulting blend effect is based on that shape. The start
and end points do not matter.
• Shapeburst (spherical): This method is similar to the Shapeburst (angular)
method except that the shape of the final render is less angular. Start and
end points are inconsequential.
• Shapeburst (dimpled): Again similar to the Shapeburst (angular) method,
but is rendered in a collapsed way. The start and end points do not affect
this technique.
• Spiral (clockwise): This renders a spiral shape in a clockwise direction.
• Spiral (anticlockwise): This renders a spiral shape in an anti-clockwise di-
rection.
Repeat This option is not available for all Gradient settings. It provides three options.
• None: This option renders the gradient normally.
• Sawtooth Wave: This renders the gradient normally, but repeats the gradi-
ent from the start and end points.
• Triangular Wave: This option renders the gradient normally and repeats the
gradient in the same fashion as Sawtooth Wave, but reverses the gradient
for every second iteration.

8.6 Brightness-Contrast
8.6.1 Overview
The Brightness - Contrast tool adjusts the brightness and contrast levels for the active
layer or selection.
8.6.2 Brightness - Contrast Options
Brightness-Contrast Settings
Brightness The Brightness slider sets a positive or negative value for the brightness
of the active selection or layer.
Contrast The Contrast slider sets a positive or negative value for the contrast level of
the active layer or selection.
