Ghost elements share many parameters in common, although specific elements have
unique parameters. These parameters are as follows:
Color: A color picker and eyedropper combination that lets you colorize that
specificelement.
Position: A slider lets you set that element’s position along the optical path that’s
defined by the angle from the (Flare) Position X and Y to the Lens Center X and Y
parameters. A value of 0 centers that element on the Lens Position, while larger
values push that element farther and farther away from the Lens Position.
Size: Sets the size of that flaring element, or in the case of the Anamorphic Streak,
the width.
Height: (Anamorphic Streak only) Sets the vertical thickness of the streak.
Center Brightness: (Aperture, Disk, and Anamorphic Streak only) Defines the
brightness in the middle of that element, filling it to appear as a solid element. Set
this closer to 0 if you want the element to appear hollow.
Edge Brightness: (All but Anamorphic Streak) Defines the brightness of the edge of
that element. Raising this value while lowering the Center Brightness lets you create
outlined element effects.
Softness: Lets you blur that element.
Bristle Density: (Corona Only) Lets you alter the number and arrangement of the
optical bristles that appear. At lower values, fewer bristles appear, at higher values,
more bristles appear. As you change the value of this parameter, the placement
of bristles shifts, allowing you to change distribution as well as density with a
singlecontrol.
Bristle Scale: (Corona only) Lets you alter the thickness of the bristles that appear.
Smaller values result in thicker bristles, higher values result in smaller bristles more
tightly packed together.
Ringing: (All types but Bubble) Simulates a pattern of diffraction artifacts. Higher
values increase the number of rings or streaks comprising the element.
Chromatic shift: Simulates chromatic aberration effects.
Eclipse Position: Simulates where the outer (away from the center) or inner (toward
the center) side of a Ghost Element doesn’t exist because the light is occluded by
the edge of a lens element or some part of the tube housing. Practically, this defines
which side of the Ghost Element is affected by the other Eclipse parameters of size,
softness, and chromatic shift. Adjusting this results in semi-circular ghost shapes of
different kinds. At 0, there is no eclipse. At positive values, the eclipse starts from
within the frame and pushes out; at negative values, the eclipse starts from the
outside of the frame and pushes in.
Eclipse Size: Defines the size of the eclipse region for that flare element. At higher
values, more and more of the flare element is eclipsed.
Eclipse Softness: Defines the softness at the transition from the eclipsed and non-
eclipsed regions.
Eclipse Chromatic shift: Lets you create a chromatic aberration effect at the
boundary of the eclipsed region. At 0, there is no chromatic shift. At increasingly
positive values, there’s a shift toward blue. Toward negative values, there’s a shift
toward red.
Repeat: Lets you use this element to spawn many duplicates defined by the
following two parameters.
Repeat Position Seed and Repeat Size Seed: At different values, these parameters
let you pseudo-randomly redistribute the placement of repeated elements.
