"Cinematographer with a preference for natural light who acted as midwife to Bergman masterpieces", says an obituary of Sven Nykvist (1922-2006) that The Guardian carried. Thanks to G P ramachandran for pointing me to this article and reminding me of a cinematographer's role in films like The Virgin Spring, The Silence, Cries and Whispers and Fanny and Alexander.
