The document discusses the lighting techniques used in three films: Kingsman: The Secret Service, Before I Disappear, and American Ultra. For Kingsman, natural tones are used with brighter colors or less saturated tones used for CGI scenes. Before I Disappear features dark lighting with colored LED lights and filters to make scenes more vibrant. American Ultra starts with natural tones but gets darker and more saturated as the intensity increases, with lights placed both in front of and behind actors to convey being chased.
