A Three-Point Home Studio

When daylight runs out, three controllable lights cover most home portrait and product work: a key to set the main shape, a fill to manage contrast, and a rim or background light to separate the subject from what is behind them. The principle is the same whether the lights are inexpensive continuous lamps or studio flash.
The three roles
Key light
The key is the dominant source and defines the direction of the shadows. Place it to one side of the camera, raised slightly above eye level and angled down, so the shadow under the nose falls naturally. A softbox or umbrella on the key widens the source and softens the shadow edge.
Fill light
The fill sits on the opposite side at lower power, lifting the shadows the key creates. Rather than adding a second lamp, you can fill with a white reflector and keep the look cleaner. The ratio between key and fill is what sets the mood: close ratios read soft and even, wide ratios read dramatic.
Rim or background light
A third light placed behind or to the side of the subject adds an edge of light along the hair or shoulders, or lifts the background so the subject does not blend into it. In a small room this light often does more for the sense of depth than extra power on the key.

Stands and low ceilings
Apartment ceilings are often close to the maximum height of common light stands, which can reach roughly 2 to 2.5 m. That leaves little room to raise a light high and angle it down. Two adjustments help:
- Move the subject closer to the camera and farther from the wall so you can keep stands lower and still get separation.
- Use a boom or a clamp to position a light without a tall vertical stand under a low ceiling.
Safety
Continuous lamps and flash heads can get warm. Keep modifiers and fabrics a safe distance from the bulb, route cables along the wall, and weight stand legs so a passing foot does not pull a light over.
Modifiers in a small space
Larger modifiers give softer light but eat floor space. A medium softbox or a shoot-through umbrella is usually the practical limit in a living room. Grids and flags help you keep the light off the walls so it does not bounce and flatten the contrast you worked to build.
