Simple little Photoshop action that comes close to rendering the Star Wars hologram effect. The only thing the action does not do is render the scan lines. After running the action use your own method for creating scan lines on a new layer. For my scan lines I used the blending method Soft Light and change the layer opacity to 25%.
The various images I tried with this action seem to render pretty clean results, but I am sure there are going to be some situation where it does not work.
If you use the action let me so I can see your artwork.
