I can think of countless films in which cinematography has impressed and influenced me, and this can be a topic of endless discussion. But for the sake of brevity I will narrow my most influential to two areas.
I enjoy film noir. These were low budget crime stories, but quality was not compromised. They were (almost all of them) black and white, which enhances the noir mood. Those old time cinematographers were absolute masters of light and shadow, composition, wet reflections, smoke and steam. To this day, if I am in a large city at night (very seldom any more since we live so remotely), especially if it has been raining, I will be out taking photographs, and thinking about Sam Spade.
I grew up with westerns, and my favorite genre still, by far, is westerns. I think any John Ford film, not just his westerns, is cinematography at its finest. During the filming of 'She Wore A Yellow Ribbon' there was to be a scene of a cavalry column in Monument Valley. It was late in the afternoon and a storm was coming in. The cinematographer, Winton C. Hoch, said there was insufficient light and wanted to shut down. Ford overruled him, said there was enough light, film the scene and he (Hoch) would win an Academy Award for best cinematographer. Hoch did film it and did win the Oscar. Ford was known to have studied the works of Charles M. Russell and Frederick Remington for ideas and inspiration. Ford was especially artful at capturing the dignity and majesty of cavalry movements. 'She Wore A Yellow Ribbon' was no fluke. The opening credits in 'The Horse Soldiers', with the cavalry silhouetted on the levee and Stan Jones' title song 'I Left My Love' being sung by the troops is masterful.
As I qualified earlier, Ford's consummate skill to set a scene and direct his cinematographers encompassed all the genres he filmed. 'The Quiet Man' has been termed John Ford's postcard from Ireland. It is a visual treat. Making that film was a labor of love for him, and it shows.
