Cinematographic and photographic techniques like shallow focus can serve your story or images in numerous ways. And mastering it isn’t overly complicated. Some filmmakers do tend to overdo these kinds of techniques to capture ‘that cinematic look,’ but being able to answer what is shallow focus and implement it in your work, is still an incredibly useful tool.
Shallow Depth of Field
What to know before shallow focus
To understand what shallow focus is, you need a firm grasp on some other photographic elements like depth of field and aperture. Make sure you’re well-versed in these, but if not, I’ll give you a quick recap from our other articles.
Aperture is a lens setting that affects depth of field.
Depth of field is the area of acceptable sharpness in front of and behind the subject on which the lens is focused. It essentially refers to how blurry or sharp the area is around your subject. The camera’s aperture controls this blurriness and sharpness by adjusting the size of the opening in the lens.A shallow depth of field describes the small or narrow area that is in focus. Often, the background is blurred while only the subject stays in focus. This shallow or small depth of field can be achieved by increasing the aperture or rather lowering the f/ number.
SHALLOW FOCUS DEFINITION
What is shallow focus?
Shallow focus is a term referring to the technique that keeps one part of an image in focus while the rest is out of focus. Shallow focus uses a shallow depth of field by either widening the aperture, increasing the focal length of the lens, or placing the camera closer to the subject to create blur. It is blurring the background and foreground around the sharp subject. It helps emphasize one part of the image over another to draw the viewer's eye to a particular area of the frame or subject.
WHAT DOES SHALLOW FOCUS DO?
- Keeps only one plane in focus
- Isolates the subject
- Direct’s viewer’s attention to particular scene element
Shallow focus is a function of a shallow depth of field.
When I use a shallow focus, I have shallow, narrow, or smaller part of the image that remains in focus. This is compared to a deep focus that keeps all of the image sharp.
Implementing this technique can serve your stories in many ways.Watch the video below to see how the filmmakers of The Handmaid’s Tale used it to tell compelling episodic television.
Knowing how and when to use this kind of focus is an art as well as a skill. Try not to use it too much, unless of course it genuinely works and enhances your narrative.
What is aperture?
To get the most out of shallow focus in your projects, you need to have a firm grasp on one specific mechanism in your camera: the aperture. If you don't know what aperture is or how it works, it will be hard to get the control of focus you want. Read up on aperture to capture the blur and texture your vision demands.
