Changing the mood of a scene through color grading

After we've taken some time to familiarize ourselves with the post process volume actor, it is now time to start looking at how to use the different functionalities we can find within it.

The first section that we will be covering is also the first one we can find if we look at the details panel for the actor and that is the Color Grading tab.

The reason these options exist in Unreal is similar to why they exist elsewhere, like in movies or videos. The end goal is to provide artists with a series of tools that they can use to alter the look of the final image. Similar techniques have been prominent in motion pictures, for example, where the captured footage is adjusted to satisfy a particular need be that the establishing of a stylized look or the ensuring of color continuity. What we are going to be doing in the following pages is exactly that tweaking of the default camera values to modify the look of our scene.
