You do not need a complex lighting rig to get professional portrait results. A single well-placed light can do most of what a multi-light setup does. Here is how.
Most photographers assume that better lighting means more lights. It does not. A single well-placed light, used with intention, produces results that a poorly designed multi-light setup cannot match. Learning to work with one light first forces you to understand light direction, quality, and shadow in a way that shortcuts with extra lights will prevent.
Simplicity forces understanding. When you only have one light, you cannot hide a bad placement decision behind a fill light or a background light. Every shadow reveals exactly where your light is coming from and how it is interacting with the subject. Photographers who master one-light setups typically have stronger lighting intuition than those who learned on complex rigs.
One-light setups are also faster, more portable, and more appropriate for on-location work where rigging multiple lights is impractical.
1. Rembrandt lighting — position the light at approximately 45 degrees above and to the side of the subject. The defining characteristic is a small triangle of light on the shadow side of the face (the cheek opposite the light). This is the most classical portrait lighting pattern, flattering for most subjects, and produces a result that reads as professional and intentional even to viewers who know nothing about photography.
2. Split lighting — position the light directly to the side of the subject at 90 degrees. One side of the face is fully lit; the other is in shadow. The result is dramatic, editorial, and high-contrast. Split lighting works well for moody portraits and editorial work but is more challenging for traditional portrait clients who expect flattering results.
3. Broad lighting — the key light is positioned on the same side that the subject's face is turned toward, illuminating the larger, more visible side of the face. This reveals more facial area and tends to be more flattering for subjects with narrower faces. It softens the appearance of strong facial features.
4. Short lighting — the key light is positioned on the opposite side from where the face is turned, illuminating the smaller, less visible side of the face. This is slimming and creates more shadow and dimension than broad lighting. It is the most common choice for flattering portrait lighting because it adds definition and reduces the apparent width of the face.

Review my real quote for $29 →A white or silver reflector positioned on the shadow side of the subject bounces some of the key light back without adding a second light source. This reduces the shadow side's darkness without eliminating it, preserving shape and dimension while lifting the exposure on the shadow side. A reflector costs $20-$40 and gives you the effect of a fill light without the added complexity of a second strobe.
The same one-light position produces very different results depending on the modifier:
If you do decide to add a second light, consider using it on the background rather than as a fill. A light on the background separates the subject from the background without changing the quality of the portrait lighting. This gives the image depth without the additional complexity of managing two lights on the subject simultaneously.
Yes — many of the most respected portrait photographers work primarily with one light. The constraint forces you to develop a stronger understanding of light placement and shadow management than most multi-light photographers ever develop. One light, used well, consistently produces professional results.
Short lighting is the most universally flattering: the key light on the side of the face turned away from camera, illuminating the shorter, less visible side. This adds shadow and dimension that narrows the face and creates definition. Pair it with a white reflector on the shadow side to lift the shadows slightly and the result is flattering for the vast majority of subjects.
Use a reflector. A white reflector on the shadow side of the subject bounces the key light back into the shadows, reducing contrast without the cost or complexity of a second strobe. You can also use a white foam board (available at any dollar store or art supply store) as an inexpensive reflector that works just as well as a commercial product for most portrait applications.
A softbox in the 24x36-inch to 36x48-inch range is the most versatile single modifier for portrait work. It produces soft, directional light with controlled spill and flatters most subjects. If portability is a priority, a shoot-through umbrella is faster to set up and produces a similar soft quality with slightly more spill. Octoboxes are a strong middle ground — rounder catchlights and slightly more wrap than a rectangular softbox.
