Beginner 3 Point Lighting

Goals

Students will learn how to create a 3-point lighting system.

Skills

  • Lights: point, sun, spot, world
  • 3-point lighting: key, fill, back
3 point lighting

Assignment Details

Create a simple scene with a three point lighting system. Render the project. Your project should include:

  1. A main subject that is a complex mesh object.
    1. You can use an object from a prior assignment.
    2. Subject should be more complex than a simple shape.
    3. Subject should have a color, material, and/or texture applied.
  2. A scene with a few other objects to test the lighting.
    1. The scene can be indoors or outdoors.
    2. At least three other objects are in the background.
    3. Background objects can be walls, tables, chairs, trees, etc.
    4. Background objects should have realistic colors, textures, and/or materials applied to them.
  3. A three-point lighting system.
    1. The lighting system lights the subject well and provides depth of field for the scene.
    2. Key light
      1. Comes in from an angle.
      2. Lights up the subject well.
    3. Fill light
      1. Comes in perpendicular to the key light.
      2. Fills in the shadows well.
    4. Backlight
      1. Comes from behind the subject.
      2. Highlights the subject to separate the subject from the background.
    5. The other objects in the scene are visible with the lighting without being blown out or completely in shadow.
  4. Camera and Rendering
    1. The camera is placed properly to view the subject and background objects.
    2. The scene renders well.

Tips

World Light

To better view your lighting, it is a good idea to turn off the World Light. The World Light is a light applied to the world around blender so that you can see things in rendered mode if you don’t have your lights set properly. It is on be default and can mess with your 3-point lighting. To turn it off go to the World Properties palette and set the Strength to zero. If you don’t have lights se properly, things will go completely black. So, watch out.
