It’s all about experimenting instill you set a perfect atmosphere that fits your needs. Basically mess with the settings - properties, as those are the only ways to properly develop realism and get that realistic lighting within your game.
I recommend tweaking and playing around with the lighting effects such as. (Color Correction, Sun Rays, Color_Shift, Bloom - technology/brightness). And adjust them instill you get that realism that fits your style. Here is a thread that goes into more depth and explains more about how to make realistic lighting using different technology uses.
