Depth of field is used to draw your attention to a specific part of the screen. A shallow depth of field means your foreground is in focus and the background is out of focus. A deep depth of field means your entire shot is in focus.
I’m going to use the short film, Earthrise, to help show off how depth of field can be used effectively. I was the writer and co-director of Earthrise and Noah was the cinematographer and did our first rough edit.
Above you can see a shallow depth of field meaning the object in the foreground is in focus on the actress in the background is out of focus.
In this shot we’re using the action from Elise Vasquez to balance out the background and make it interesting while leaving our focus on actor RJ Wagner.
The example above is a scene where we shift focus between the two actresses on screen. The depth of field is deeper so that they’re only just out of focus enough to direct your attention where we want it to go.
