Depth of Focus is a photography term. Two of the characters use cameras. Maureen, the middle sister, is a documentary filmmaker and Barbara, the youngest, is a still photographer. For each of them, we have a unique camera.
Maureen uses a Sony DSR-PDX10 DVCAM camera. This is the camera we shot Impasse with, it was used as the TV studio camera in Nudged, and it returns again as a prop in the new film. Maureen will use the camera during interviews employing a method developed by Jennifer Fox called “passing the camera.” During an interview the subject and the filmmaker pass the camera back and forth. The camera has two microphones so both parties can speak and be recorded.
The method is explained in this article from Documentary Magazine, “The ‘passing the camera’ technique becomes the great equalizer, as no one person in the conversation has more power than the other. Both film each other, both can ask questions of the other, both people are equally on the line. “On top of that,” Fox adds, “the whole question, ‘Can a layperson shoot with a camera?’ is so obviously answered in the film. My camera instruction to each woman took about 30 seconds, and within 30 seconds they were filming me, often quite beautifully.”
Barbara uses a Bronica ETRS medium format film camera that was made in the 1980’s. The film used in this camera is 2 inches wide and the resulting image is huge and detailed. Barbara’s camera has been converted to use a digital chip rather than film. This makes it more practical for modern photography.
There are several ways to convert the ETRS camera to digital recording, Jeff Bauers describes one approach. Barbara’s camera conversion is simpler than what is shown in the article and practically indistinguishable from the film version.
