Using post-processing
Post-processing is a Unity feature that allows us to apply a stack of effects (several effects) one on top of the other that will alter the final look of an image. Each one will affect the finished frame, changing the colors in it based on different criteria. In Figure 13.1, you can see a scene before and after applying image effects. You will notice a dramatic difference, but that scene doesn’t have any change in its objects, including lights, particles, or meshes.
The effects applied are based on a per-pixel level. Have a look at both scenes here:
