Lighting used in 'The River'

I choose lighting carefully when directing our film, making sure the opening which was a somewhat happier scene had high key lighting, gradually decreasing as the story progressed and the characters went deeper into the wood eventually dieing at nightfall. This is done in a wide range of film by using lighting to convey the emotions of character, 'dark' a connotation for misery, brightness for happiness etc. I also took use of such pathetic fallacy when directing emphasising the situation and mood of the characters to audience, somewhat subconsciously.
