Professional photographers create attractive portraits by using specialized equipment such as off-camera flashes, ring lights, reflectors, etc. Their photographic expertise enables them to capture their subjects with illumination at just the right angle and intensity. This disclosure describes techniques to simulate a directional light source on portraits at any time post-capture. The simulated light source can heighten the depth-of-field and enhance facial contours, resulting in a studio-quality look. The techniques enable any user of a smartphone or other camera to obtain portrait photographs that emulate high quality professional portrait photographs by automatic and dynamic adjustment of the lighting in the image.
