The document summarizes the lighting techniques used in two music videos. In the Calvin Harris video, bright outdoor lighting is contrasted with softer indoor lighting to frame Rhianna inside a glowing cube. The lighting matches the tempo of the music as it speeds up. In the Lady Gaga video, harsh artificial light introduces the artist and dancers before shifting to softer light mimicking a sunrise; darker lighting is used to foreshadow negative events while brighter lighting follows.
