Mimics the out-of-focus effect that occurs through a real-world camera lens. The Defocus
filter blurs an image while creating realistic lens artifacts that mimic the aperture shape
in brighter areas of the image. The shape of the blur can be customized.
Tip: Use this filter when you are trying to blur an image to match video or stills shot with
a camera. For example, if you key a woman standing in front of a blue screen, and you
intend to place a background image behind her to make it look like she’s standing in a
valley with mountains in the background, use the Defocus filter instead of a Gaussian
Blur to create a realistic depth-of-field effect for the mountains in the distance.
