 # Vignette
 
-In Photography, vignetting is the term used for the darkening and/or desaturating towards the edges of an image compared to the center. This is usually caused by thick or stacked filters, secondary lenses, and improper lens hoods. It is also often used for artistic effect, such as to draw focus to the center of an image.
+The **Vignette** effect darkens the edges of an image, leaving the center of the image brighter. For more information on the Vignette effect, see the [Vignette](https://docs.unity3d.com/Manual/PostProcessing-Vignette.html) documentation in the Unity manual.
 
+The Vignette effect in the post-processing stack has two modes:

+- [Classic](#classic)
+- [Masked](#masked)
 
 
-The Vignette effect in the post-processing stack comes in 2 modes:
-
-- Classic
-- Masked

-- Shader Model 3

-See the [Graphics Hardware Capabilities and Emulation](https://docs.unity3d.com/Manual/GraphicsEmulation.html) page for further details and a list of compliant hardware.

 ## Classic
 
-Classic mode offers parametric controls for the position, shape and intensity of the Vignette. This is the most common way to use the effect.
