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.
