What is post processing unity?

Post processing in Unity refers to the application of visual effects to a rendered image or video after it has been generated. This process can bring a touch of realism and make the game or virtual experience more immersive for the players. Some of the common post processing effects in Unity include color grading, bloom, lens distortion, noise, and motion blur. These effects are applied using post-processing scripts and can be adjusted using sliders and parameters. Post processing can also be used to optimize the performance of the game or application by reducing the number of polygons or textures of the scene. Overall, post processing is an important component of game development, as it enhances the aesthetic appeal of the game and provides a more engaging and interactive experience.
