One light is all you need for a flattering portrait if you control three things: where it sits, how close it is, and how large it looks to the subject. The routine below works with a flash, a continuous lamp or even a bright window.
Set up in five moves
- Place your subject a few steps away from any wall so the background falls into shadow or stays evenly lit.
- Put the light at roughly forty-five degrees to one side of the camera, a little above eye level, angled gently downward.
- Bring it close. A nearer light looks larger and gives softer shadows, so aim for about one to two arm spans from the face if you can.
- Add a diffuser, such as a translucent panel or umbrella, to enlarge and soften the source.
- Take a test frame, check the nose shadow and eye sparkle, and nudge the light until the shadow forms a small loop.
Control the shadows without a second light
The shadow side of the face can look heavy. You have free fixes:
- Hold a white card or foam board opposite the light to bounce some light back.
- Stand near a light-colored wall, which acts as a fill.
- Turn the subject slightly toward the light so more of the face is lit.
- Raise the overall exposure by a third of a stop if the shadow side looks muddy.
Match the setup to the look you want
| Goal | Light placement | Distance |
|---|---|---|
| Soft and friendly | Front-side, large diffuser | Close |
| Moody | Far side, no fill | Medium |
| Bright and clean | Near the lens, high | Close, with a bounce card below |
Troubleshooting
If the face looks shiny, move the light farther away or raise it slightly, and lightly powder the skin. If eyes look dark, raise the light so a catchlight appears in the upper part of each eye. If the background goes black when you wanted detail, bring the subject closer to the wall or lower your shutter speed with continuous light.
Always follow the maker’s manual for any flash or lamp, keep cables out of walkways, and let hot lamps cool before moving them.
FAQ
Is flash or a continuous lamp better for one-light work?
Continuous light lets you see the effect live, which helps while learning. Flash freezes motion and can overpower the sun. Both follow the same placement rules.
How far should the light be from the subject?
Closer makes it softer but lights the face unevenly if you go too near. A distance of a couple of arm spans is a comfortable middle.
The Short Version
Place the light about forty-five degrees to the side and slightly above eye level, bring it close, soften it, and bounce a white card to fill shadows. Adjust until the nose shadow forms a gentle loop.
