This is an old technique that was invented in the early 70's way back when Kodachrome 64 film was around where you actually burn the transparency with a flame. This shot of George Newsholme was run in a feature in an early Skateboarders Journal were I mucked around burning the crap out of a bunch of trannies with a gas burner then sandwiched them between glass and scanned them. If you're down to try it make sure you use a few crap trannies first, they go up in flames very easily.
