What is a recommended 1 light portrait setup for capturing stunning portraits?

A recommended 1 light portrait setup for capturing stunning portraits is to use a single softbox or umbrella positioned at a 45-degree angle to the subject, slightly above eye level. This setup creates soft, flattering light that highlights the subject's features and creates a pleasing catchlight in the eyes. Adjust the distance and power of the light to control the intensity and shadows in the portrait.
