Lens Blur

Blurs the layer like a real camera lens, producing bokeh-style highlights and a cinematic defocus look.

Blur Map lets you pick another layer whose brightness controls how much each pixel blurs, for faking depth of field. Lighter areas blur more, darker stay sharp. Toggle Invert Map to flip that.

Map Channel, Map Fit, and Map Source configure how the map is read and positioned.

Radius controls the blur amount.

Pre-Blur softens the map before the Lens Blur pass. It can get rid of some artifacting when Blur Amount is set to higher values.

Highlight and Highlight Threshold boost bright pixels into visible bokeh circles — raise Highlight to bloom the brightest areas, lower Threshold to include more pixels.

Iris Aspect Ratio stretches the bokeh shape — above 1 elongates horizontally, below 1 vertically.
