Overview

What LensBlur does

Simulates lens defocus using real or creative aperture shapes, quality controls, highlight behavior and optional external aperture input.

LensBlur models defocus through an aperture shape rather than simply averaging pixels. Shape, aperture settings, anamorphism, rotation and highlight controls determine whether the bokeh feels circular, polygonal, anamorphic or deliberately stylized.

It is heavier than GaussianBlur and usually deserves a staged setup: establish Blur Size and aperture shape first, then refine anamorphism, highlight response and chroma shift. Use a clean mask or depth branch when only selected planes should fall out of focus.

When to use it

Create cinematic bokeh
Defocus practical lights
Simulate polygonal aperture blades
Use custom aperture shapes
Build stylized optical blur
