A quick heads-up for my film-fan-friends here ... there's an excellent documentary that's been on cable this month, which I caught in an art house years ago ... it's called Visions Of Light: The Art of Cinematography from 1992.
All you classic movie people ( Heather!! I thought of you immediately ) will really appreciate all the movies featured, and you contemporary film fans will enjoy the comparisons.
Honestly, it's a great documentary - covers the details, the true art of the cinematographer. Covers movies from the first black and white films through Goodfellas.
It's got to be available on Netflix.
