Depth Of Field Film

Short Depth Of Field
This is where in the image only a certain part or specific point in the image is in focus such as a persons body but not the background of anyone else, maybe just a persons hands, face, or feet.
This depth of field would be used to draw attention to someone or something, a photographer would use a short depth of field to draw the viewers attention to something.
Using depth of field can allow a director or photographer to tel a story without words.

First image

This image is from scream the TV series when Emma is getting a phone call from the killer. This scene fits perfect with a short depth of field focusing completely on Emma to show her reaction, and forces the viewers to look at her and know she is the main focus of this sense.






Long Depth of Field
Long depth is where lots of the image is in focus therefore showing more of whats happening in the scene.
An example of this is in crime series, where the investigators, and the body are in the same shot and all in focus to show the whole sense and allow the viewer to understand exactly whats happening. Its very common in crime films and series because there are lots of people apart of an investigation that are in the same scenes more than not,therefore a long depth of field would be better suited.
