Far from instant and the only filters are on the front of lenses.

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.
