Split Diopter
Half the lens carries a close-up element, so a near face and a far face are both sharp with a visible seam between them.

Split Diopter
Half-lens creating simultaneous sharp focus on two depth planes.
circular bokeh · minimal flare · sharp
Best for: Suspense, Brian De Palma style, Dual focus
Picking the technique sets these controls; it does not paste text into a prompt. The setting can be re-run, checked against the settings beside it, and carried into the next shot.
Also in composition
What the glass does to the frame: how much of it is sharp, how wide it reads, what the edges do.
- Shallow FocusBasic · Cinematic, Romantic
- Only a thin slice of the scene is sharp. Isolates the subject from its surroundings and is most of what makes an image read as 'cinematic'.
- Deep FocusAdvanced · Dramatic, Documentary
- Everything from foreground to horizon is sharp. Lets action play out on several planes at once instead of directing the eye by focus.
- AnamorphicIntermediate · Cinematic
- Squeezed capture that yields a very wide frame, oval bokeh and horizontal blue flares. The most recognisable 'big film' signature there is.
- Vintage GlassIntermediate · Nostalgic, Romantic
- Older uncoated lenses: lower contrast, swirling backgrounds and flares that bloom easily. Imperfection used deliberately.
- Tilt-ShiftAdvanced · Artistic
- The focus plane is tilted off perpendicular, leaving a narrow band sharp across the frame. On a wide view it makes real places look like models.
Reads the same way
Other techniques that read as dramatic — a light or a lens to pair with this move.
- Low AngleBasic · Dramatic, Cinematic
- The camera sits below the subject and looks up. Reach for it when someone should read as powerful, imposing, or in control of the room.
- High AngleBasic · Dramatic
- The camera looks down on the subject. The inverse of a low angle — it diminishes, and is the standard way to make someone read as vulnerable.
- Steep OverheadIntermediate · Dramatic, Artistic
- Steeply down but not fully vertical. Keeps faces readable while a true bird's eye loses them — the usual choice when you want the detachment but still need performance.
- Profile ShotBasic · Artistic, Dramatic
- Dead side-on, ninety degrees to the subject's facing. Reads as formal and observational — you are watching rather than being addressed.
- Behind the SubjectIntermediate · Cinematic, Dramatic
- Directly behind, seeing what they see. Puts the viewer at the character's shoulder and makes the environment ahead the subject of the shot.
- Over-the-ShoulderBasic · Cinematic, Dramatic
- From behind and to one side, with the near shoulder in frame. The workhorse of dialogue coverage — it fixes who is looking at whom.
- Extreme Close-UpBasic · Dramatic, Horror
- A detail filling the frame — eyes, hands, an object. Removes all context, which is exactly why it reads as intense or claustrophobic.
- Close-UpBasic · Dramatic, Cinematic
- Head and shoulders. The standard shot for performance — close enough that the face carries the scene.
- Dolly ZoomAdvanced · Horror, Dramatic
- Track in while zooming out (or the reverse). The subject stays the same size while the background rushes — the standard visual for dread or realisation.
- Push InBasic · Dramatic, Cinematic
- The camera moves steadily toward the subject. The most reliable way to tell an audience that this moment matters.
- Rack FocusAdvanced · Dramatic, Cinematic
- Focus shifts from one plane to another mid-shot. Redirects the viewer's attention without moving the camera or cutting.
- Dutch AngleBasic · Horror, Dramatic
- The horizon is tilted. Signals that something is wrong — the most legible unease cue in the language.
- SnorricamAdvanced · Horror, Dramatic
- The camera is rigged to the actor, so they stay locked in frame while the world lurches behind them. Disorientation, or dissociation.
- ChiaroscuroAdvanced · Dramatic, Artistic
- Extreme contrast between light and dark with very little in between. Borrowed from Baroque painting; the darkness does as much work as the light.
- Rembrandt LightingIntermediate · Dramatic, Cinematic
- Key light high and to one side, leaving a small triangle of light on the shadowed cheek. The classical portrait setup.
- Split LightingIntermediate · Dramatic, Horror
- The light comes from ninety degrees to the side, so half the face is lit and half is in shadow. Reads as division or duplicity.
- Rim LightBasic · Cinematic, Dramatic
- Light from behind that traces a bright edge around the subject, separating them from the background. Almost every night exterior uses it.
- SilhouetteIntermediate · Artistic, Dramatic
- The subject is unlit against a bright background, reduced to outline. Identity withheld — shape carries the whole shot.
- Harsh NoonIntermediate · Documentary, Dramatic
- Overhead midday sun. Short hard shadows and blown highlights — usually avoided, which is exactly why it reads as unglamorous and real.
- Bleach BypassAdvanced · Dramatic, Action
- Skipping the bleach step leaves silver in the print: contrast climbs, colour drains, grain hardens. Harsh and metallic.
