My/Our first assignment of year two CyberARTS surrounds the different types of lighting and portraits for Photography. There are six different types that we are to research on. Here are examples of each.
1. Split lightingThis type of lighting has light shine on only one side of the subject's face, while the other half is completely dimmed from light/has no light shining on it, making it dark.

2.Loop lighting    Loop lighting is made by creating a small shadow of the subject's noses on their cheeks. To create loop lighting, the light source must be slightly higher than eye level and about 30-45 degrees from the camera.

3.  Rembrandt Lighting Rembrandt lighting is identified by the triangle of light on the cheek. Unlike loop lighting where the shadow of the nose and cheek do not touch, in Rembrandt lighting they do meet which, creates that trapped little triangle of light in the middle.

4. Butterfly/Glamour lighting Butterfly lighting is aptly named for the butterfly shaped shadow that is created under the nose by placing the main light source above and directly behind the camera. The photographer is basically shooting underneath the light source for this pattern. It is most often used for glamour style shots and to create shadows under the cheeks and chin. It is also flattering for older subjects as it emphasizes wrinkles less than side lighting.

5. Broad loop  Broad lighting is when the subject’s face is slightly turned away from center, and the side of the face which is toward the camera (is broader) is in the light. This produces a larger area of light on the face, and a shadow side which appears smaller. Broad lighting is sometimes used for “high key” portraits.

6. Short lighting In short lighting, the face is turned towards the light source this time. Notice how the part of the face that is turned away from the camera has the most light on it and the shadows are falling on the near side of the face, closet to the camera. Simply put short lighting has shadows on the largest part of the face showing.
