Those pictures that Kodak used to print showing glowing hot items were made using very special very long wave IR film, not the usual stuff sold mostly for special effect pictures. ??? Maybe I don't recall seeing those pictures, but I do recall seeing a KODAK picture described as being taken in total darkness using two, hot, ironing board irons as the "light" source, 45 degrees from the subject, one on each side of the lens-subject axis,. I think it was made with Kodak's High Speed Infrared... (well, it might have been an aerial film, but I seem to remember it as their regular 35mm infrared film) Does anyone know for sure? I think it said an exposure time of 8 minutes was used. Ray ____________________________________________________________________________________ Never miss a thing.
