The Lens Vignette tool mimics a real-world lens vignette. A lens vignette occurs when the light that enters the lens is partially blocked by the barrel, causing a natural decrease in brightness around the edges of the frame.

Vignette: Controls how much vignetteing is added to the image.

Amount: Controls the strength of the Vignetteing effect. Higher/positive values darken the edges of the vignette while Lower/Negative values can remove/reduce vignetteing.

Highlights: Preserves highlight detail when the vignette is applied. When set to 0%, Lens Vignette will apply a vignette regardless of highlight detail. Positive values will allow highlight detail to not be affected by the vignette, providing a more realistic Lens Vignette.

Center X: Offsets the center point of the vignette on the X axis.

Center Y: Offsets the center point of the vignette on the Y axis.

Aspect: Adjusts the shape of the center of the vignette on the X axis.

Anamorphic: The Anamorphic checkbox will adjust the overall lens vignette to mimic an anamorphic lens if turned on.
