This is a re-post from 2008. Still timeless.

Many films are beautifully shot. Few, though, are as consistently well composed as Chinatown (1974)*. Shot in Panavision (anamorphic) format with a 2.35:1 aspect ratio the somewhat extreme rectangular image would seem to offer significant challenges to effective image composition. As I was pondering this challenge I was struck by how much I loved the images in Chinatown, which I just watched again the other day. That’s when I went back to basics and considered that even with widescreen images there are still fundamentals of composition at play. In this case I figured I would grab a few images (one from each major scene) from the film and apply the Rule of Thirds to each image.

The Rule of Thirds is simply as follows:

Divide the image into thirds, both horizontally and vertically, then put the focus of the image either one third across (from either side) or one third up or down the screen. Those lines, and the points at which they intersect, are the strongest invisible forces in an image.

In Chinatown the images are constructed around those lines and intersecting points. By doing this the aspect ratio becomes a relatively mute point as the human brain automatically takes in the whole image, mentally divides the image into thirds, and finds pleasure as key visual elements are constructed around those thirds. Of course, deviation from the power of the thirds creates visual tension, which is an additional tool in the filmmaker’s toolbox.

Chinatown was shot by John A. Alonzo. He was nominated for an Oscar for best cinematography. Here are the images from the film (I, of course, added the white lines):
