### 6.9. Vignette

#### 6.9.1. Overview

In photography, vignetting is a reduction of the image brightness toward periphery. It is often an undesired effect due to camera settings or lens limitations. But it is also deliberately used to draw attention to the center of the image. “Vignette” can produce this effect.

  | 참고
  These options are described in 2절. “공통 특징”.

Vignette shape

  - Circle

  - Square

  - Diamond

  The shape of the vignette (ellipse or circle for example) depends on Proportion setting.

Radius

  How far out vignetting goes as part of half image diagonal.

  Radius = 0.700

Softness

  TODO.

  Softness = 0.100

Gamma

  Falloff linearity controls the curve of the falloff from the center to periphery: set how fast is brightness reduced towards edges of the vignette.

  Gamma = 1.00

Proportion

  Proportion is particular: with the default value (maxi) 1.00, the vignette is a circle in a square image and an ellipse in a rectangular image. Reducing Proportion, this ellipse tends to a circle.

Squeeze

  Aspect ratio to use:

  - 0.0 = 1:1

  - 0.5 = 2:1

    Diamond shape, proportion = 0.0 and squeeze = 0.5

  - 1.0 = completely squeezed vertically

  - -0.5 = 1:2

  - -1.0 = completely squeezed horizontally

  | 참고
  To directly use squeeze factor as proportion, set Proportion to 0.0.

Center X, Center Y

  Coordinates of vignette center. Origin is the upper left corner of the image. 1.00 is the right border of the image. The center can be placed outside of the image.

Rotation

  Rotation of the vignette. The vignette keeps its shape.
