This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
Light rays emanating from the center of the image, shining through current selection.
"Spikyness" adds variation to the radial spokes.
"Illumination" increases the brightness of the light source (selection).
"Contrast" helps in bringing out the colors of the original in the rays.
"Directional" makes the light rays less (or more) diffused. The effect is more obvious with low "Spikyness" settings.
"Effect Level" controls the blend of the original image and image with effect applied.
(Tip: Keep "Seamless" checkbox checked to avoid a seam from the center to the top on image. Filter only works with "Size, pixels" maximized, on square images.)
