Welcome to the community! So, it depends on how you want to handle it. If you'd like to modify the base post-process settings -- that is, the native appearance of your entire map -- then from the main menu at the top left corner of the editor, select View, then World Properties. There are a lot of important settings to mess with here in regards to the way your map looks and behaves, but you'll mostly want to delve into the DefaultPostProcessSettings tab. There you will find control over ambient occlusion, depth of field, bloom, and things of that nature.

Now, if you want to control these effects dynamically -- that is, for example, have different effects occur in different areas of the map -- you'll want to either use a PostProcessVolume or control your own custom effects via Kismet. For now, I'd recommend starting with the PostProcessVolume in this case. Simply use the Builder Brush to encompass the area you want to be affected, then right-click the Volumes button on the left-hand toolbar and choose PostProcessVolume. Move the Builder Brush away to see the PostProcessVolume -- it should have a thin pink outline. With this volume selected, hit the F4 key to bring up its properties menu and click through to PostProcessVolume ---> Settings. There you'll find the same types of settings, as well as controls over how long the transition will be from "normal" to "post-processed" once the player has entered the volume.

I hope that helps get you started! Please let me know if you have any further questions and I'll be happy to help out.
