In this example, we will look at a few of the post processing effects in action. As I am learning, there are many resources to check out, and you can experiment with several settings to change the look of your game. The first effect we can experiment with is Bloom, which makes bright areas in your game glow more.

The next effect we will try is color grading, which changes the tone, brightness, and contrast of your game environment.

Once Color Grading is active, there is one update needed to the Project Settings, as noted by the exclamation point. The Color Space in Project Settings need to be switched to Linear for HDR mode.

The Project Settings can be accessed through the File Menu Build Settings or the Edit drop down menu.

Unity File drop down, go to Build Settings

Under the Player tab in Project settings, change the Color Space from Gamma to Linear.

Back in the Color Grading effect, we can update the Tonemapping to Neutral or ACES, and we can also experiment with the White Balance, which affects the overall tint and temperature of the environment.

After experimenting with several of the effects, here is an example of the before and after.
