The 7 Lighting Patterns Every Filmmaker Needs to Know

Flat, Loop, Rembrandt, Split, Rim, Silhouette, Butterfly — what they are, how to place the fixture, and when to use each one.

By the MACCAM Team · Lighting Fundamentals Series

Every lighting decision a gaffer makes comes down to one question: where does the shadow fall? The shadow tells the story. It shapes the face, defines the mood, and signals to the audience — consciously or not — how to feel about the person on screen. The seven lighting patterns covered here are not arbitrary categories. They represent the full range of where a key light can be placed relative to a subject's face, and what that placement does to the shadow geometry. Master these seven and you have a complete vocabulary for any portrait or interview situation.

These patterns apply equally whether you're lighting with an ARRI SkyPanel on a studio stage or a single LED panel in a run-and-gun documentary. The fixture changes. The physics doesn't. What follows is the complete breakdown — placement diagrams, shadow behavior, and the use cases where each pattern earns its place.

1. Flat Lighting

Also called: On-axis light · News light · Beauty flat · Fill-only look

Flat lighting is a portrait pattern where the key light is positioned within 30° of the camera axis, producing a shadowless, low-contrast look on the subject's face. Because the light is coming from the same direction the camera is pointing, shadows fall behind the subject, out of frame.

Placement: Key light within 30° of the camera axis — basically on-axis with the lens. The source is close to the camera, at roughly the same height as the subject's face. The result is a shadowless, dimensionless look. No modeling, no depth, no drama.

That's not always a liability. Flat lighting works for news broadcasts, corporate talking heads, and YouTube content where the goal is clean clarity over cinematic mood. It's also a legitimate starting point for beauty work when combined with a bounce below — opening up the under-eye area and smoothing skin.

The risk: without shadow to define structure, faces lose dimension. Someone with strong bone structure can carry flat light. Someone with a softer face will look washed out. Know your subject before defaulting to flat.

2. Loop Lighting

Also called: Standard portrait · Natural light · Hollywood natural · Portrait lighting

Loop lighting is a portrait pattern where the key light sits at roughly 45° to the side and slightly above eye level, producing a small shadow that loops from the bottom of the nose toward the corner of the mouth. That shadow is where the name comes from and how you identify the pattern on any face.

Placement: Key light at roughly 45° to the side of the subject, slightly above eye level. The defining characteristic is the small nose shadow angling toward the corner of the mouth.

Loop is the default starting point for most cinematographers. It creates natural, flattering dimension without the drama of Rembrandt or Split. The shadow is present enough to add depth but not so dominant that it reads as stylized. It's the pattern that mimics how natural window light falls on a face.

Height matters here. Key too low and the shadow flattens. Key too high and the shadow drops too far — you start crossing into Rembrandt territory. The sweet spot is a fixture at roughly 30–45° above horizontal, sending the shadow cleanly downward at a shallow angle. Most portraits that look "naturally lit" are using loop with a fill card or low-output fill on the shadow side.

3. Rembrandt Lighting

Also called: 45/45 · Dutch light · Triangle light · Painter's light

Rembrandt lighting is a portrait pattern where the key light sits at roughly 60° horizontal and 45° above the subject, creating a signature inverted triangle of light on the shadow-side cheek. Named after the Dutch master who used this exact pattern in his portraits, it conveys weight, character, and drama.

Placement: Key light at approximately 60° to the side of the subject, with meaningful height — roughly 45° above horizontal. The combination of lateral and vertical angle causes most of the far side of the face to fall into shadow, with one exception: a small, inverted triangle of light appears on the shadow-side cheek, lit by reflection off the nose.

It's a pattern that makes faces interesting. Lines, texture, and bone structure are revealed rather than smoothed over. For documentary subjects, period films, and any scene requiring gravitas, Rembrandt is the go-to.

The technical check: the triangle must be fully formed — connected at the top to the cheekbone, pointed at the bottom, roughly the size of the nose or smaller. If the triangle closes (shadow takes over completely) or doesn't appear at all, you're either too side-on or not high enough. The triangle is the calibration target.

4. Split Lighting

Also called: Side light · Half-and-half · Profile light · Hatchet light (extreme version)

Split lighting is a portrait pattern where the key light is placed at exactly 90° to the side of the subject at face height, dividing the face into a fully lit half and a fully shadowed half along the vertical midline. No other pattern divides the face this cleanly.

Placement: Key light at exactly 90° to the side of the subject, at the same height as the face. The light strikes only one half of the face. The vertical midline becomes a hard shadow boundary. The result is a face divided cleanly in half — one side fully lit, one side fully dark.

Split is the most dramatically intentional of the face-lighting patterns. It doesn't feel accidental or natural — it feels directed. When a cinematographer uses split, they're making a conscious statement about the character: duality, conflict, hidden nature, moral ambiguity. It's the pattern used for villains, antiheroes, and anyone the audience should approach with suspicion.

The variation called hatchet light takes split further — the fixture is placed high enough that the shadow cuts diagonally across the face, like a hatchet blade, rather than cleanly down the center. Both are split family. The reflector shown in the diagram above is optional: adding a bounce or low-power fill on the shadow side pulls it back from pure dramatic silhouette into something more controlled and usable for close-up work.

5. Rim Lighting

Also called: Edge light · Kicker · Separation light · Accent light · Hair light (when aimed at head)

Rim lighting is a separation technique where one or two fixtures are placed behind the subject at roughly 120° from camera, illuminating only the edges — shoulder, hair, jaw — to lift the subject off the background. It's almost never the only source in a scene.

Placement: Two fixtures behind the subject, each at roughly 120° from camera, aimed back toward the lens. They light only the edges, leaving the front of the face dark. The result is a halo effect that outlines the subject against the background.

Rim light is a separation tool, not a key light strategy. When a subject's dark jacket and dark hair disappear into a dark background, rim is the fix — it lifts the edges of the subject off the background, restoring depth to the frame. Every three-point setup uses this principle: key for shape, fill for shadow control, rim for separation.

When aimed specifically at the hair and top of the head, the same placement is called a hair light. When only one rim is used, on the same side as the fill, it becomes a kicker. All the same physics, different naming conventions depending on context. As a standalone look — pure rim with no front illumination — it reads as abstract, mysterious, or stylized. Music videos use it constantly.

6. Silhouette

Also called: Contre-jour · Against the light · Backlit silhouette · Upstage light

Silhouette is a lighting approach where a single source is placed directly behind the subject at 180°, illuminating the background while leaving the subject's face and body completely unlit. Identity is withheld; only shape remains.

Placement: A single light directly behind the subject at 180° — the light source is between the subject and the background, aimed at the background. The subject blocks the light entirely, casting itself as a dark shape against the illuminated background. No front illumination at all.

Silhouette is not a lighting pattern in the same sense as the others — it's a deliberate removal of light from the face. The subject becomes a shape, a form, a presence. It's the technique used for anonymous interview subjects in documentary, for revealing moments at the end of a scene, for anything where the shape of a person tells more than their face would.

The French term contre-jour (against the daylight) captures the technique's origin in natural light photography — placing a subject between the camera and a window, letting the window blow out while the subject goes dark. On a controlled set, the same effect requires a bright background light and the discipline to leave the front of the subject completely unlit.

7. Butterfly / Paramount Lighting

Also called: Paramount light · Glamour light · Moth light · Clamshell (when fill bounce added below)

Butterfly lighting — also called Paramount lighting — is a portrait pattern where the key light is placed directly above and in front of the subject, creating a small, symmetrical shadow beneath the nose shaped like a butterfly. It's the signature glamour look of Hollywood's Golden Age.

Placement: Key light directly in front of the subject, above and angled down at roughly 45°. The shadow falls straight down from the nose, creating a small, symmetrical shape underneath it — the butterfly. Because the light is centered above the face, both sides of the face are evenly lit. The overall effect is symmetrical, elegant, and flattering.

Butterfly was the lighting of choice for Hollywood's Golden Age portrait photographers. Cecil Beaton, George Hurrell, and the studio photographers who built the visual identities of Marlene Dietrich and Joan Crawford all used this pattern. It's named Paramount because that studio's in-house photographers formalized it as their house style. For subjects with strong cheekbones, it's extraordinarily flattering — the downward angle deepens the hollow beneath the cheekbones and lifts the overall impression of the face.

The clamshell variation adds a large bounce card or soft fill panel below the subject, angled upward to reflect light back into the under-eye shadows. This is the contemporary beauty standard — you'll see it in every cosmetic commercial, every fashion still. The top light sculpts, the bottom fill softens.

The Angle Progression: All Seven at a Glance

The horizontal axis above represents the angle of the key light around the subject. As you move from camera-front toward behind the subject, shadow behavior changes continuously. The named patterns are not separate categories — they're landmarks on a spectrum. Understanding where you are on that spectrum at any moment is the core skill of portrait lighting.

Choosing the Right Pattern on Set

Start with the story, not the technique. Before you decide where to put the fixture, decide what the audience should feel about this person in this moment. A detective being interrogated might warrant split or Rembrandt. A lead character in a warm scene with their family calls for loop. A beauty close-up in a commercial almost always lands on butterfly or clamshell. The pattern is in service of the story.

Your fill ratio determines how aggressive the pattern reads. Rembrandt with heavy fill looks almost like loop. Split with a soft fill card looks like a mild Rembrandt. Every pattern exists on a dial between harsh and soft, and that dial is controlled by how much light you allow on the shadow side. A 4:1 ratio (key two stops brighter than fill) reads natural. A 16:1 or deeper starts to look stylized, regardless of which base pattern you're using.

Shadow tells you where the light is. When you're on set and trying to understand what the gaffer before you set up, or when you're troubleshooting a look that isn't working — read the shadow. The shadow under the nose tells you the lateral angle. The shadow depth tells you the height. That one habit — reading the shadow first — will make you faster and more intentional at every lighting position.

Frequently Asked Questions

What are the 7 main lighting patterns in film?
The seven classic lighting patterns are Flat, Loop, Rembrandt, Split, Rim, Silhouette, and Butterfly (Paramount). They're defined by where the key light sits relative to the subject's face and what shape of shadow that placement produces.

What's the difference between loop and Rembrandt lighting?
Loop lighting uses a key light at ~45° and produces a small nose shadow that stops short of the cheek. Rembrandt uses a key at ~60° with more elevation, pushing the shadow until it meets the cheek shadow — leaving only a small inverted triangle of light on the shadow-side cheek. Rembrandt is more dramatic; loop is more natural.

When should I use split lighting?
Split lighting is best for characters meant to feel conflicted, duplicitous, or morally ambiguous — villains, antiheroes, interrogation scenes, noir. It's a deliberate, stylized choice that reads as directed rather than natural.

What is butterfly lighting used for?
Butterfly (Paramount) lighting is the Hollywood glamour standard. It's used for beauty shots, fashion portraits, cosmetic commercials, and any subject whose cheekbones and symmetry you want to emphasize. Adding a bounce below creates the clamshell variant used in most modern beauty work.

Is rim lighting used alone?
Rarely. Rim light is a separation tool — it lifts a subject off the background and is almost always combined with a key and fill. On its own, it produces a stylized, silhouetted look common in music videos and concert photography.
