Stereoscopic 3D – “Tool” versus “Medium”:
In the still shot from the old Alfred Hitchcock 3D movie Dial M for Murder (click for bigger image), one scene shows a plot being hatched between the two actors. What is of interest to us, is the lamp in the foreground that is out of focus. If this were a regular 2D movie, it would not be of consequence, and would in fact add to and suggest “depth” in the scene. In 3D however, it looks like a blurry mess if the audience tries to resolve the details of the carvings on the sides of the lamp or tries to see the objects on the table in front.
This brings up two interesting points. Should everything be in focus in a 3D movie? and secondly should the use of depth-of-field, an established technique in 2D cinematography to be given equal importance as a story telling technique when used in making stereoscopic 3D movies.
