Butterfly lighting places the key near the face’s horizontal centerline and above it, creating a small downward nose shadow. It is also commonly called Paramount lighting. Separate the two axes: moving the light to the side changes the pattern differently from raising it.
The useful starting question is “where is the shadow?” rather than “is the stand at exactly 45 degrees?” Face orientation, source size, distance and elevation all affect the result.
Side view and top-down view
These existing diagrams are retained at their original URLs. Their distances and angles are illustrative starting geometry, not universal measurements. A side view explains elevation; a top-down view explains lateral alignment. Read them together and adjust the light by observing the sitter.
Build the pattern
- Choose camera position and framing first. Align the key approximately with the front of the face; a head turned away changes that relationship.
- Raise and aim the key until a small nose shadow appears. The often-used halfway-to-the-upper-lip target is a teaching reference, not an anatomical rule.
- Check the eyes and cheek shadows. If the eyes lose the desired illumination, lower or redirect the source rather than applying a fixed height to every person.
- Adjust apparent source size for the desired shadow edge. A larger nearby source generally gives a broader transition than a smaller distant source.
- Take a frame at the intended exposure and review it with the sitter. Support overhead equipment according to its rated system and appropriate studio practice.
Profoto’s butterfly tutorial demonstrates the raised frontal key. Its photographs belong to that source; the diagrams here are teaching references, not reproductions of that shoot.
Too low, useful starting shape, too high
The three faces are simplified illustrations. “Correct” in the existing graphic means its chosen teaching target, not the only acceptable portrait. A very low key may reduce the downward shadow; a very high key can darken the eyes. Brow, nose, head angle, hats and source size change the exact result.
Add a reflector to make a clamshell arrangement
A reflector below the face can open the chin and eye shadows. Move it closer for more fill, or farther away for less, while watching its reflection in the eyes. White and silver surfaces can produce different strengths and catchlights. There is no universal requirement that fill be exactly one stop below the key.
Profoto’s clamshell demonstration combines a raised frontal source with a lower white reflector. Keep the sitter comfortable and leave room to breathe and move; do not use the reflector to force a posture.
Butterfly, loop, Rembrandt and split
Qualification for the retained progression graphic: horizontal angle is only one variable. Elevation, head rotation, source size and facial structure also determine whether nose and cheek shadows connect. The illustration is a simplified comparison, not a one-dimensional law.
| Pattern | What to look for |
|---|---|
| Butterfly | Small, approximately centered downward nose shadow |
| Loop | Nose shadow falls to one side without joining the cheek shadow |
| Rembrandt | Nose and cheek shadows connect, leaving a lit area beneath the farther eye |
| Split | A pronounced division between the lit and shaded sides of the face |
Broad and short lighting describe which side of a turned face is illuminated relative to the camera. They are another description of the arrangement, not a ranking of attractive and unattractive faces. See split lighting for a different pattern.
Choose the modifier for the desired texture
A beauty dish, softbox or umbrella can all create a raised frontal key. Their apparent size, diffusion, distance and spill matter more than a rule that one modifier always hides texture. A grid limits spread; it does not guarantee the same shadow hardness at every distance.
Set aperture for depth of field and adjust light output to it. With flash, use a supported sync setting. With continuous light, check motion blur and flicker. Keep a record of the actual light/modifier and distance; “1/8 power” alone is not a transferable exposure recipe.
Glasses, eye shape and expression
There is no gender or face-shape restriction on this pattern. Ask what presentation the sitter wants. If glasses reflect the source over the eyes, make a small light-position or comfortable head-angle change, then recheck the pattern. Do not assume a frontal source always avoids glare.
For eyes shaded by the brow, lower the light, change its size or add restrained fill. Preserve the expression and posture the person can hold comfortably. The headshot-lighting guide covers troubleshooting, and the portrait-direction sheet offers specific spoken cues.
Test the pattern in four frames
Keep the camera and sitter in a comfortable fixed position, then change the key while leaving the other variables alone. This proposed exercise helps distinguish a placement problem from an exposure problem.
- Frontal reference: begin with the source near the face’s horizontal centerline. Make a frame and note the nose shadow and illumination in the eyes.
- Raised key: raise and aim the source a little. Look for the downward shadow, then check whether the brow is shading the eyes more than intended.
- Small head turn: keep the source fixed and have the sitter turn slightly if comfortable. Notice how a pattern that was centered can become asymmetric even though the stand did not move.
- Controlled fill: return to the agreed pose and introduce a lower reflector. Compare shadow brightness and catchlights with the earlier frame.
Save the frames together with the actual source, modifier, distance and settings. For a short session, one useful pattern and one controlled variation can be more productive than moving through every named lighting setup.
Diagnose the shadow, catchlights and background separately
| Observation | Change to test | Check afterward |
|---|---|---|
| Nose shadow falls strongly to one side | Align the source with the direction the face is pointing | Both eye areas and the desired expression |
| Nose shadow extends into the mouth area | Lower the key or adjust its aim in a small increment | Whether the downward pattern still reads |
| Shadow shape is good but too dense | Add or reposition fill without moving the key first | Glasses and lower catchlights |
| Skin texture is more pronounced than intended | Compare a larger apparent source and refine its direction | Shadow edge and important facial detail |
| Face looks right but the backdrop is wrong | Change background distance or control background illumination | Spill returning onto the face |
A catchlight is a reflection of the source; it is not a measurement of how much light reaches every part of the eye. Likewise, a clear nose shadow does not automatically mean the photograph suits the sitter. Review the overall expression and intended use alongside the pattern.
Choose butterfly lighting for a reason
Try it when a frontal arrangement and roughly symmetrical modeling serve the portrait. Compare a loop pattern when the head needs to turn farther, or a broader source and more fill when a gentler transition fits the brief. A deeper shadow can be intentional. The name of a pattern does not determine whether a portrait must look glamorous, severe or flattering.
For an independent photographed demonstration, Hannah Couzens’s Profoto tutorial shows a raised frontal source. Use such a demonstration to understand the relationship, then judge your own subject and room rather than copying equipment output numbers.
Can a window produce butterfly lighting?
Yes, if the effective light direction is high enough relative to the face. The window’s height, the sitter’s position and any diffusion determine the pattern. A window is not disqualified by its room label, and an arbitrary distance rule does not replace looking at the shadows.
A film-set “butterfly” can also mean a large framed diffusion or other textile. That equipment term is different from this portrait-lighting pattern. This guide does not assign the pattern a single inventor; the previous historical attribution was not adequately established.
