Post-processing overview

Post-processing is the process of applying full-screen filters and effects to a camera’s image buffer before it is displayed to screen. It can drastically improve the visuals of your product with little setup time.

You can use post-processing effects to simulate physical camera and film properties; for example; Bloom, Depth of Field, Chromatic Aberration or Color Grading.

Using post-processing

To use post-processing in your project you can import Unity’s post-processing stack. You can also write your own post-processing effects. See Writing post-processing effects for details.
