You can make professional headshots with one light by placing a large, soft source slightly above and to one side of the subject, adding a reflector or white wall opposite for fill, and using a mid-range aperture for sharp eyes. One light keeps the setup simple and the results consistent. The numbers below are general baselines to refine.

Choose and Place the Light
A single light can be a flash, a continuous panel or even a bright window. What matters is size and position. A larger modifier relative to the subject creates softer light and gentler shadows.
- Use a softbox, an umbrella or a large window as the source.
- Place the light about 30 to 45 degrees to one side and slightly above eye level, aimed down at the face.
- Bring it close, roughly one to three feet from the subject, for softer light.
- Place a white reflector, foam board or wall on the opposite side to lift the shadows.
Set Up the Camera
- Use manual mode and shoot RAW.
- Choose an aperture of f/4 to f/8. This keeps both eyes and the face sharp while softening the background.
- Pick a shutter speed at or below the flash sync speed, commonly around 1/125 to 1/200, and check your camera’s limit. With continuous light, 1/125 or faster is typical.
- Use a low ISO, such as 100 to 400.
- Use a lens of about 70mm to 135mm on a full frame body, which flatters facial proportions. A 50mm lens works with more distance.
- Focus on the nearest eye with eye detection autofocus if available.
Adjust the light power until the face looks bright but not shiny. Use the histogram and zoom in to check skin tones.
Common Lighting Patterns
- Loop lighting: the light sits a little above and to the side, creating a small shadow of the nose on the cheek. It suits most faces.
- Butterfly lighting: the light sits above and in front, giving a symmetrical look with a shadow under the nose.
- Short lighting: the side of the face turned away from the camera receives the light, which adds shape.
Posing and Direction
Ask the subject to turn their body slightly away from the camera and then bring the face back toward the lens. Have them lean slightly toward you and push the forehead forward a little, which defines the jawline. Keep conversation going to relax them, and shoot many frames. Check for blinks, clothing collars and stray hair.
FAQ
What background should I use?
A plain wall, a gray or white backdrop, or a window-lit interior works well. Keep the subject a few feet from the background to separate them.
Do I need glasses glare control?
Lift the light a bit higher and angle the subject’s chin slightly down to move reflections out of the lenses.
The Short Version
Use a large soft source at 30 to 45 degrees, fill with a reflector and shoot at f/4 to f/8. Direct your subject, check the frames and keep the setup repeatable.
