Aperture Diffraction
Found in the ResolveFX Light category, Aperture Diffraction models the starburst effect usually
seen when shooting bright lights with small apertures, the physical cause of which is light-
diffraction on the aperture blades of a lens. This plug-in simulates this, with the result being
automatically applied to scene highlights that you can isolate and refine, with customizable
virtual apertures.
Small regions of brightness exhibit a star pattern glow, as seen in the following image.

Large regions of brightness exhibit a more even glow with shaping and texture that look like a
natural optical effect. It can be used to create a different type of glow effect with a more
realistic look in some situations than the Glow plug-in, though it’s more processor intensive. In
other situations, this plug-in opens up many different stylistic possibilities for glowing effects.

Output
These controls let you choose what image is output by this plug-in.
 Select Output: Lets you preview the image with different stages of the Aperture
Diffraction effect applied, viewing the Isolated Source (to help when adjusting the
Isolation controls), Preview Aperture (to help when adjusting the Aperture controls),
Preview Diffraction Pattern (showing you the resulting diffraction pattern based on the
aperture control settings), Diffraction Patterns Alone (showing you the glow effect that
will be applied to the image by itself), and the Final Composite.
 Quality: Lets you choose a quality setting to trade off between quality and speed.
Choices are Full, Half (Faster), Quarter (Fast).
