Denotation
Deep focus is a photographic and cinematographic technique using a large depth of field. Depth of field is the front-to-back range of focus in an image, or how much of it appears sharp and clear. In deep focus, the foreground, middle ground, and background are all in focus.
Description
Deep focus refers to a cinematographic technique in which both the foreground and background of a shot are in Sharp Focus simultaneously. This is achieved through the use of a deep depth of field which means a large portion of the frame is in focus from objects close to the camera to those far away.
Deep Focus technique is achieved through the use of a small aperture allowing for a greater range of distances to be in focus. Deep focus cinematography is not merely a technical choice but is also laden with Narrative and aesthetic significance.
The opposite of Deep Focus is shallow focus where only a narrow plane of the image is in sharp focus while the foreground or background may be blurred. Deep focus is often used to capture a wide view of the scene allowing the audience to see and interpret details in both the foreground and background simultaneously. This technique can be employed for various creative and narrative purposes such as emphasizing the spatial relationships between characters and elements in the frame or conveying a sense of realism by presenting a scene in a way that mimics the way the Human Eye Perceives the world. Directors like Orson Welles, known for his work in "Citizen Kane" are often associated with the innovative use of deep focus in cinema.
From a technical standpoint, deep focus requires careful consideration of lighting, lens selection and camera settings. Cinematographers must balance these factors to ensure that the entire scene remains in focus enabling the audience to engage with multiple visual elements within the frame.
Narratively, the use of deep focus can serve various purposes. It allows directors to emphasize spatial relationships highlighting interactions between Characters and their environment. By presenting a comprehensive view of the scene, deep focus can contribute to the storytelling by providing additional visual information or symbolism. This technique can also create a heightened sense of realism, as it mirrors the way the human eye naturally perceives a scene.
