Secondary flares are the small circles you would
normally see coming out from the source of the
lens flare along an axis relative to the camera
position. These are caused by light refracting
off the different lens elements in the camera.
As the camera position change s relative to the
source object, the secondary flares move. These
secondary flares are automatically generated when
this option is selected in the Preferences section
of the dialog.
You c reate sets of s econdary elements that share
common parameters instead of building them one
at a time. Many of the controls on the A Sec panel
are for individual sets of elements, not all sets.
Inter face
Min—Controls the minimum size of secondary
flares in the current set. This number is defined as
a percentage of the overal l image. This parameter
can be
animated (page 3–365)
.
Max—Controls the maximum size of secondary
flares in the current set. This number is defined as
a percentage of the overal l image. This parameter
can be
animated (page 3–365)
.
Sets—Specifies which set of secondar y flares you
are working with. You can have as many sets of
automatic secondary elements as you wish, each
having their own properties. By defau lt, seven
sets are a vailable. You can scroll through them
by clicking the forward and reverse arrow icons
besidethenameoftheset.
To add another set to your flare, click the Add
button beneath the On check b ox. To delete a set,
click the Del button.
Axis—Defines the overall length of the axis the
automatic secondary flares will be distr ibuted
along. Increasing the value creates more space
between the flares, while decreasing the va lue
creates less space between the flares. You can set
the axis from 0 to 5 degrees. This parameter can
be
animated (page 3–365)
.
On—Defines whether a group or set of secondary
flares is active or not.
Fade—Determineswhetherornotaxialfadeis
active for the current set of secondary flares.
Hue—Specifies the gradation of color of the
secondary flares. This parameter can be animated.
Qty —Controls the number of secondary flares that
appear in the current set of flares. This parameter
can be animated.
Shape—Controls the shape of the secondar y flares
for the current s et. The default value is circular, but
you can choose from 3 to 8 sided secondary flares.
Gra dients—Defines the
gradient (page 3–392)
for
the secondary flare.
