this tutorial is based on the work of John Kahrs, Lighting for
Computer Graphics, Pixel Cinematography Course notes, Siggraph '96
The basic key/fill/rim lighting combination is a standard live-action approach that has been around for a long time.
The Key light is the primary source of illumination.
The Fill light softens and fills the shadows created by the Key.
The Rim or Kicker is a backlight that provides highlights and rim lighting around the edge of the subject. It is often what differentiates the subject from the background.

original setup, one spot dead center makes the subjects look flat and uninteresting.
Start with one keylight, in this case a spotlight, angled at 3/4
Next, turn off the key and work with the fill light,
created with a low-intensity ambient and spot with intensity, neither
cast shadows. Use the fill to lighten up the dark areas on the right
side of the figures. The Fill is positioned on the opposite side of the
key in this case.
Now turn the key back on and view the key and fill lights together
Turn the key and the fill off and work with the Rim light to give you
highlights on the edges of the figures. This Rim light will also cast
the decay and dropoff were added and the fill's intensity was bumped up

This tutorial will introduce the student to the use of a three-light setup for lighting in a scene.
Students will download the provided Maya or Studio scene file which contains the models without lights. All of the shaders for models are provided in the file. The correct camera angle which is the current perspective camera. Students will create a lighting model that takes into consideration all light sources and reflected light that appear in the provided scene.
This project will result in the creation of still images which display a defined lighting situations.
Students will email the instructor typed answers to the questions below.
