Ha! thats a very good, neat question. Actually... my answer may be not of a help / use for you, not at all: it is a flexible film with matte mirroring surface, ready-made - I did not added anything to my editing. Last year I found a big plazma TV being moved to a local damp, it was broken, and the screen had a few such films. I enjoyed how it looks like and stole one, considering it can serve as a good background. That is all.
