Types of Gradients 395
you set in one gradient are used exclusively to
achieve the effect.
Avera ge—Calculates an average value between the
colors. In the example above, the resulting color
would b e 175, 225, 225. This option is good if you
want to mix g radient values and results in effects
that are not as bright as High Value.
Low V a lue —Selects the lower color values, resulting

would be 100,210,295.
Additiv e—Adds colors values together, pushing
their composite value tow ard pure white,
producing the brightest but most washed-out
effects.Additivecompositingisgoodwhenyou

other, resulting in slightly muted and less intense
colors.
These compositing methods may be applied to all
t ypes of gradients, except size gradients. The type
of compositing being used for a gradient is noted
above the gradient bar.
Compositing methods are applied to every
gradient. Some gradients are lin ked together, so if
you assign a specific compositing method to one,
the compositing method is automatically assigned
to the other.

There are two different kinds of gradients in Lens
Effects, Radial and Circular. B e tween the two
types, you can achieve almost limitless effects.
Interfa ce
Radial—Radial gradients work from the center
point to the outer edge of a Lens Effects feature,
changing color or brightness in a straight line from

edge of the gradient is a ligned with the center of
the effect and the right edge is aligned with the
outer edge of the effect.

Circul ar—Changes colors in a circular manner,
working clockwise around a Lens Effects feat ure. If
you mark North, East, South, and West on a circle,
these points represent the 0%, 25%, 50%, and 75%
marks of the gradient.
Each parameter panel in Flare, Glow, and
Highlight that utilizes gradients contain five
gradient controls. The five controls are:
