You can match the lighting from a still image by creating a light rig based on the image's lighting characteristics. The light rig is a set of infinite lights whose colors, directions, and intensities simulate the lighting in the source image. Because the lights are infinite, scene objects are lit the same way regardless of their locations and you don't have to worry about positioning the lights or resizing the rig.
Creating a light rig places a set of infinite lights in your scene. The lights simulate the brightness, direction, and color of the lighting in the source image.
