Lighting Schemes for Photo and Video

All diagrams are top views: camera at the bottom, subject in the centre, lights as amber circles with rays, reflectors as dashed bars, backdrop as the thick line at the top. Angles are measured from the camera–subject axis: 0° is frontal light next to the lens, 45° is the portrait classic, 90° is strictly side-on. These are the same setups we build by hand in class: position first, then the height of the light, and only then the modifiers.

Any complex scheme breaks down into four roles. The key light is the main source: it models the face and creates the shadows. The fill is soft and weak (usually 1.5–3 stops below the key): it lifts shadows, never erases them. The rim (hair light) shines from behind and above, separating the subject from the background with a bright edge. The background light works on the backdrop alone: a gradient, a spot, a colour.

The diagram shows the classic three-point base plus a background instrument. The key-to-fill ratio sets the mood: 2:1 reads soft and reportage-like, 4:1 is a stronger portrait with real shadows, 8:1 and beyond is dramatic low key. Start with the key alone, look at the shadows, and only then decide whether you need a fill. The most common beginner mistake is switching on all four lights at once without knowing what each one does.

Lighting is classified along three axes. By source: natural (sun, window) and artificial (flash, continuous). By character: hard — a small source far away, crisp shadows; soft — a large source close to the subject, shadow edges dissolve. The rule of thumb: the size of the source relative to the subject decides softness, which is why a metre-square softbox next to the face is softer than a tiny lamp across the room at the same power.

By direction: frontal light flattens, 45° light is the working portrait classic, side light sculpts texture and ages, backlight shoots into the lens and makes a silhouette or a halo. A separate axis is tonality: high key — a predominantly light frame with even fill on a light background; low key — a predominantly dark frame built on one hard source. Tonality is decided by the background and the fill before any styling enters.

The four classic portrait schemes differ in the position of the key relative to the face. All four work on any budget: three of them need only one light and a reflector.

Rembrandt: the triangle under the eye

The key sits 45° to the side and 45° above the subject’s head. A small triangle of light appears on the shadowed cheek under the eye; if there is no triangle, raise the light or move it sideways until there is. Fill is minimal, two to three stops down. The result is a sculptural, painterly portrait with depth and character.

Use it for: male portraits, dramatic characters, textured faces — wrinkles, beards, working hands. Caution: the scheme exaggerates asymmetry, so for a wide nose or deep-set eyes the softer loop is kinder.

Loop: the working classic

The key at 30–45° to the side, slightly above eye line: the nose shadow loops down and sideways without touching the cheek shadow. The result is a face with modelling but no drama — the most universal scheme that flatters almost everyone. Use it for editorial portraits, LinkedIn-style headshots, corporate subjects, school and wedding series — anywhere a pleasant, predictable result is needed in ten minutes.

Butterfly: glamour symmetry

The light sits directly in front of the subject, high above: the nose shadow falls as a symmetric butterfly beneath it, and a reflector under the chin fills the shadows under the eyes and jaw. The result is an effervescent cinematic face with lifted cheekbones — the Hollywood portrait of the 1930s–40s. Use it for beauty and fashion, and for subjects with even features; on wide faces it adds weight, and the loop is a kinder choice.

Split: the face in halves

The source sits at a strict 90°: half the face is lit, half in shadow, with no fill or next to none. The result is the strongest character statement of the base schemes — tension, inner conflict, musicians and actors on posters. Use it when a single frame has to say something sharp; in commercial portraiture it is rare, in authorial work — constant.

In an interview the subject talks and the camera barely moves, so the lighting has to survive half an hour of conversation without surprises — a shiny forehead, crawling shadows, a dead gaze. Three rules follow: a soft key (a large softbox or umbrella), fill no stronger than 2:1 against the key, and a rim that separates the head from the background.

One light and a reflector

A softbox at 45° off the camera–subject axis, just above head height; a reflector on the opposite side returns part of the light to the shadowed cheek. The subject looks not into the lens but at the interviewer next to it. The result is a lively, dimensional frame that assembles in fifteen minutes on any location — the documentary filmmaker’s minimum.

Three lights: key, fill, rim

A rim light is added behind the subject and a weak fill near the camera. The rim separates dark hair from a dark background — its absence is what makes interviews look flat. Keep the fill close to a 2:1 ratio: movement in frame (gestures, head turns) forgives less than a static portrait. Use it for studio interviews, corporate video and talking-head channels — anywhere there is time to set up and a guaranteed result is required.

The background is a separate decision, not decoration. If the subject sits close to a wall, any rim loses its effect: keep at least a metre and a half of air between the subject and the backdrop. A dark background with a rim gives cinematic depth, a light one gives a clean editorial look, and a coloured background or a gel on the background light adds mood without a single camera move. The same rule covers windows in frame: when the street is visible behind the subject, expose for the face and let the window blow out — or kill it with a curtain.

Product work lives at the intersection of three decisions: the form is drawn by a soft key through a diffuser (a shooting tent, a grid softbox, or simply a sheet of paper in front of the source), the edges are picked out by a rim light behind, and the background receives a gradient — a bright spot behind the object that cuts it off the backdrop. Camera on a tripod; the aperture serves depth of field, not exposure.

The result is a dimensional product with clean edges and controlled highlights. Use it for catalogues, marketplaces, menus, advertising. Practical note: glossy objects (glass, metal) are photographed not as objects but as whatever they reflect — change not the light but the shape of the big white plane around the camera.

In the studio you control everything — backdrop, no windows, lights on stands — so a scheme from this guide reproduces exactly. On location the main light is already there: the window or the sun. The working OCF (off-camera flash) approach adds a flash on a stand as the key and treats the existing light as fill or rim: the sun behind the subject becomes the rim, the flash becomes the key.

A practical proportion: in the studio 80% of the time goes into exact light placement, on location 80% goes into the speed of decisions, because the sun moves and the client waits. That is why every scheme in this guide should once be built at home with a friend and memorised by hand: on location there will be no time to derive Rembrandt by trial and error.

A separate tool on the border of studio and location is colour temperature and gels. Mixing daylight with tungsten in one frame can be deliberate: a cool background and a warm face works in both portraits and interviews. The rule is simple: motivate the light with the story — a window, a monitor screen, a lamp inside the frame justify the direction and colour, while an arbitrary source “from nowhere” reads as a mistake even in a beautiful frame.

• Switching on all the lights at once — and being unable to say what each does. The order: key → look → fill → look → rim → background.
• Fill at the key’s level: the shadows disappear along with the volume. When in doubt, remove fill rather than add it.
• Hard light from a small instrument “for a portrait”: the softbox must be large relative to the face and stand close.
• The rim crawling into frame and hitting the lens: move it sideways out of the frame instead of dialling the power to zero.
• Subject and background lit by one instrument: the subject sticks to the backdrop. Even a modest background light adds depth.
• One pattern for everything: Rembrandt does not flatter wide faces, butterfly punishes asymmetry, and split in commercial portraiture is almost always too much.
• Judging light by “looks fine”: check the nose shadow and the catchlights — everything else follows.

This guide is the open version of what we teach in the “Photographic Lighting: Theory and Practice” course: modules on key and fill, modifiers, off-camera flash, interviews and gels. The companion course “Optics and Camera Equipment” covers the technical side — exposure, lenses, camera handling. Commercial schools cover the same ground — Inlight Academy, Shot Academy and ProPhotoStudy run paid studio-lighting courses; the difference of this guide is that it is complete, open, and checkable before you pay.

How these schemes behave in motion is visible in the filmography: between fiction scenes and interviews the logic of key, fill and rim is the same, just with a moving camera. The guide will be updated as students ask new questions — the best schemes are born from mistakes made in practice.
