Using postprocessing effects
One of the ways that we can improve the visual quality of our game with little effort is by using postprocessing effects (previously called Image Effects). Postprocessing is the process of applying filters and other effects to what the camera will draw (the image buffer) before it is displayed on screen.
Unity includes a number of effects in its freely available postprocessing stack. Unity’s postprocessing stack is a set of visual effects that can be applied to the rendered images in a game or application to enhance the overall visual quality. These effects can include things like color grading, depth of field, motion blur, ambient occlusion, and more. By using the postprocessing stack, developers can easily add these effects to their games without having to create them from scratch.
The term “stack” is used to emphasize that these effects are designed to be used together, in a layered manner, to achieve a desired visual style...
