This is the most common way of using only one gradient. Set one gradient to
the color or brightness you desire, then set the other gradient to pure black.
This assures that all of the values you set in one gradient are used exclusively
to achieve the effect.
Average Calculates an average value between the colors. In the example
above, the resulting color would be 175, 225, 225. This option is good if you
want to mix gradient values and results in effects that are not as bright as
High Value.
Low Value Selects the lower color values, resulting in a less intense lens flare
and a more subtle overall effect. In the example above, the resulting color
would be 100,210,295.
Additive Adds colors values together, pushing their composite value toward
pure white, producing the brightest but most washed-out effects. Additive
compositing is good when you want to burn effects out.
Subtractive Subtracts colors values from each other, resulting in slightly
muted and less intense colors.
These compositing methods may be applied to all types 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 linked
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.
Between the two types, you can achieve almost limitless effects.
Interface
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 left
to right as you scan the gradient bar. The left edge of the gradient is aligned
with the center of the effect and the right edge is aligned with the outer edge
of the effect.
