For the fourth section of the project I used BCC’s Film Damage filter. It allows you to add scratches, grain particles, hair or fibers, and dirt, dust, or water spots. It also allows you to simulate camera shake and a flickering image. The color effects were the result of using the Difference mode; a mathematical operation that combines pixels on one layer of a composition with the layer behind it. In this composition I had a royal blue solid behind the layer with the keyed hand. The Difference mode I applied to the hand layer used the luminance values of the two layers and interpolated new values based on the difference.
