DRAMA: This works best in daylight and other well-lit environments. This can also be used to brighten dark scenes.
DRAMA_NIGHT: This works best at night or in dark environments with minimal light sources. I recommend using grain and bloom. You may teed to tweak bloom if the light source in your scene is too bright.
