Fig. 1. The results of our portrait enhancement method on real-world portrait photographs. Casual portrait photographs often suffer from undesirable shadows, particularly foreign shadows cast by external objects, and dark facial shadows cast by the face upon itself under harsh illumination. We propose an automated technique for enhancing these poorly-lit portrait photographs by removing unwanted foreign shadows, reducing harsh facial shadows, and adding synthetic fill lights. Casually-taken portrait photographs often suffer from unflattering lighting and shadowing because of suboptimal conditions in the environment. Aesthetic qualities such as the position and softness of shadows and the lighting ratio between the bright and dark parts of the face are frequently determined by the constraints of the environment rather than by the photographer. Professionals address this issue by adding light shaping tools such as scrims, bounce cards, and flashes. In this paper, we present a computational approach that gives casual photographers some of this control, thereby
