so the ultra pink IR shots are taken with the hot filter still in place? I know this is possible, but that exposures are greatly lengthened to the order of minutes sometimes as the cut filter only lets small amounts of IR wavelengths pass. I was under the assumption that shooting with a naked sensor and an IR only filter would have the same results, but with normal exposure times. That's actually why I asked if the filter was in place in all of these pictures. Clearly more spectrum is coming through if you ask me. I never thought that mixing the two would look so drastic and almost flat. Interesting.
