I have an old Canon rangefinder that I use only for IR. I put aluminum tape on the film pressure plate to make it shinny. It increased the "AURA" effect. You can get this tape at a hardware store. It is just aluminum foil with a sticky backing. I is 2 inches wide. Cover your pressure plate and then trip off the extra with a razor. I have never tried to remove it so think about it being a one way conversion with an old camera. You may never get the sticky stuff off the pressure plate if you remove the tape.
