On May 26, while teaching at the School of Photography with Youth With A Mission (YWAM) in Dunham, Quebec, Canada, I spent time showing students one of the most practical lighting setups I know: clamshell lighting, sometimes called butterfly lighting with fill.
If I have to photograph a lot of people in a short period of time—corporate headshots, conference attendees, staff portraits, missionaries, or workshop participants—this setup is one of the first things I consider.
Why?
Because it gives you consistency.
And consistency becomes your best friend when people keep stepping in front of your camera.
Clamshell lighting is named after the shape the lights create when viewed from the side. One light sits above the subject, angled downward, while another sits below, angled upward, creating the appearance of an open clamshell surrounding the face. The result is soft, flattering light that minimizes harsh shadows while still maintaining facial shape. It has become a standard setup for beauty photography and professional headshots because it works on a wide range of faces and skin types.
The Setup We Used

For the in-class exercise, I recommended using the same modifier above and below the subject. We used softboxes of roughly the same size.
My basic setup looked like this:
- Top softbox: about 45° downward toward the face (main light)
- Bottom softbox: about 45° upward toward the face (fill light)
- Background light: +2 stops to create a clean white background

For exposure:
- Main (top) light = base exposure
- Bottom fill light = 1–2 stops lower than the main light
- Background light = about 2 stops brighter than the subject
The top light creates the shape and direction of the portrait. The lower light simply opens the shadows and softens the transition areas.
If the lower light is as powerful as the main light, the image often becomes too flat. Keeping it one or two stops lower preserves dimension while still reducing under-eye shadows and smoothing skin texture. Typical clamshell ratios often keep the lower source noticeably weaker than the key light.
Why I Like This for Workshops and High-Volume Portraits
One thing I particularly like about using two similar-sized softboxes is the flexibility.
People move.
Even after you tell someone to stay still, they naturally turn their head slightly or lean toward one side.
With a narrower lighting setup, small movements can completely change the look. Suddenly, one side of the face goes dark, shadows become uneven, or catchlights disappear.
With this setup, your subject can comfortably rotate approximately 45° left or right, and the lighting still remains attractive.
That means less time fixing lights and more time connecting with people.
And connection matters more than light placement.

Watch the Eyes
One of the signature features of clamshell lighting is the catchlights in the eyes.
You’ll often see two reflections:
- One catchlight from the upper light
- One from the lower light
Those reflections create life in the portrait. Many photographers spend time adding sparkle to eyes in post-production, but good lighting often creates it naturally. Double catchlights are a common characteristic of clamshell setups.
Common Mistakes Students Make
While teaching this setup, I noticed a few things students often run into:
Placing the top light too high
When the light is too high, shadows under the nose and eyes become more pronounced. You start moving toward dramatic butterfly lighting rather than soft clamshell lighting.
Making the lower light too bright
If the bottom light becomes equal to or brighter than the top light, faces lose shape. Portraits can start looking flat and unnatural.
Putting lights too far away
The closer the light source is to the subject, the softer the light becomes. Move those softboxes farther away and they become effectively smaller, producing harder shadows.
Ignoring the background
Clamshell lighting creates beautiful light on the face, but it doesn’t automatically separate subjects from the background. That’s one reason I used a background light approximately two stops brighter than the subject—to create a clean white background and separation. Additional rim or hair lights can also add depth if desired.
One More Thought
Lighting patterns are tools, not rules.
Students often ask, “What’s the best lighting setup?”
The answer is always: the one that helps tell the story and serves the subject.
Clamshell lighting isn’t ideal for everything. If you want drama, mystery, character, or strong texture, side lighting may be a better choice.
But if your goal is approachable, clean, flattering portraits for a large number of people, clamshell lighting is difficult to beat.
Sometimes the best lighting setup isn’t the most dramatic one.
It’s the one that lets you focus less on your gear and more on the person in front of your camera.
