Add component, Post processing Volume.

This will allow you to add a profile and being adding image effects.

Check the “is Global” box so the entire environment, camera, everything being viewed will be affected.

Select New next to the profile. This will create a profile under the scene folder in the asset view.

Select the post process in the hierarchy. On the inspector view select add effect, Unity, then bloom.

You won’t be able to see the effects take place. To have those effects take place you need to enable the main camera to render the effects.

Select main camera and add component Post Process Layer.

To create a layer, select post process from the hierarchy and at the top of the inspector select the layer drop box and add a layer named Post Process.

Now the bloom will affect the look of your game. You now know how to add post processing to your game. With this you can change the look and feel of the game and take your game to the next level.
