Post Processing (Post Processing / Post Processing) is a technical term that is extremely important in the rendering and optimization of game graphics (technical art). A technology that completely changes the atmosphere of the screen by applying physical effects of the camera lens (Bloom, chromatic aberration, tone mapping, etc.) to the 2D screen after rendering is complete.
Real-world analogy: Applying "professional retouching/Instagram filters" to raw 3D photos taken
Post-processing href="/article/term-frame-buffer">frame buffer) is a retouching process for color correction and special effects lens effects performed in a darkroom.'' When a 3D world is rendered, it is simply a collection of precise 3D objects. In addition, there is ``Bloom'' (light blur) that blurs strong highlights and emit light, ``Vignette'' (vignetting) that darkens the edge of the screen, and ``Color Grading'' that changes the color tone dramatically. href="/article/term-color-grading-grading">Color grading)' is applied all at once to create a rich atmosphere as if it were shot in a movie or with a film camera.

Detailed mechanism and operating principle
URP's Volume system is placed in the scene, and Bloom (overflow of light) and Color Set Adjustments (tonal correction), Tonemapping (light/dark compression), and enable "Post Processing" in the camera rendering options.
