Deep Focus
A technique using a large depth of field so that the foreground, middle-ground, and background are all in sharp focus.
In depth
Championed by Orson Welles in 'Citizen Kane', deep focus allows directors to stage complex action in multiple planes of depth simultaneously, letting the viewer choose where to look without cutting.
Example
“Key scenes in 'Citizen Kane' where a child plays in the snow in the far background while adults discuss his future in the foreground.”
Origin and history
Deep focus became technically practical in the 1930s and 1940s as faster film stocks and more powerful lighting allowed cinematographers to stop down lenses for greater depth of field. Gregg Toland's work on 'Citizen Kane' (1941) is the textbook example, and his techniques on that film influenced decades of staging. Andre Bazin, the influential French film critic, used deep focus as a centerpiece of his theory that cinema's truth came from preserving real space rather than fragmenting it.
Why filmmakers use it
Deep focus respects the integrity of the frame. Rather than telling the audience where to look through edits, the director allows simultaneous information across multiple planes and lets the viewer's eye choose. This produces a fundamentally different audience experience than shallow focus — less guided, more participatory, often more theatrical. Modern directors use deep focus selectively, often for ensemble compositions or staging that emphasizes power dynamics across distance.
More examples in cinema
- Paul Thomas Anderson uses deep focus throughout 'There Will Be Blood' to keep oil rigs and characters readable across enormous landscapes.
- Wes Anderson's compositions frequently use deep focus to keep symmetrical multi-plane staging readable in a single shot.
Common confusion
Deep focus is not the same as 'everything in focus' from a smartphone camera. Smartphone deep focus is a side effect of small sensors; cinematic deep focus is a deliberate choice that requires lighting and lens control on large-format cameras.
