Experiment: Image Lingo Filter : Rays of Light (2001)
This filter takes a single source image to render this rays of light effect. You create this effect by copying the same image on top of each other many times. Each time you copy the image you move the image with a small step, scale it a little up and make it a little more transparent. I tried to create this filter in real-time but in order to speed up the process the quality became too poor. So I decided to pre-render an animation.
The rainbow color effect is achived by splitting the image into seperate R, G, and B layers. The colors appear when you compose the three layers back into one again and use a slight offset for each layer.
