A great example of a non naturalistic lighting change in mainstream cinema. The fade of light coinciding with the slowing of the visuals and the introduction of music is a subtle way of telling the audience everything they need to know about whats to come. The colour of the light helps to create a warm, protective feeling and despite seconds earlier having seen a gun and knowing the probable outcome, from the moment the lights dim and the music comes up, there seems to be an overwhelming sense of peace. I believe this effect was desired because it sets up an opportunity for Gosling to show both extreme's of his previously reserved personality. The intense kiss highlights his ability to be compassionate and protective and his violent capabilities, emphasised as a result the tranquil sequence just before.
