Deep Focus

How does deep depth of field affect the audience's film experience?  Why would a filmmaker want to use shallow vs. deep depth of field?

    Deep depth of field affects the audience's film experience as it allows them to see more in the frame and gives them more autonomy in what they decide to focus on. It can also allow the filmmaker to take on a more painting-like approach to the image by having details and meaning packed in a single shot. A filmmaker may want to use shallow depth of field because it allows them more control over the audience's attention and it produces a more "cinematic" aesthetic. A filmmaker may wish to use a deep depth of field because of the previously mentioned technique, but it can also be used to show off detailed sets, extreme long shots, a large number of people, etc.
