From a scientific website:

Thermal Infrared (Thermal IR) sensors do not detect reflected radiation, they are tuned to respond to emitted heat energy (thermal wavelengths). Photography's Color Infrared (CIR) uses special film, lenses and filters to capture reflected near infrared energy (sometimes called Near IR), NOT emitted thermal infrared (heat). Common misconceptions about "Infrared Photography" are that even though EMR (Electro Magnetic Radiation) in those wavelengths are sometimes labeled as part of the "visible" spectrum, these wavelengths cannot be sensed by our eyes and are NOT IN ANY WAY associated with heat. Standard filament light bulbs, like a glowing white hot metal rod, emit thermal infrared wavelengths and are a good source of radiate heat (Thermal Infrared) but not a very efficient source of visible light (the percentage of visible white light emitted by a filament light bulb, based its temperature, is very small compared to the percentage that is given off as invisible thermal energy that does not help us see). Color Infrared (CIR) photographs result from film that has reacted to sunlight that has been REFLECTED from the surface, NOT emitted (that's Thermal IR).

I can see why madmikie had to use those settings to get the image, perhaps getting thermal IR.

What is the typical exposure time of the normal camera IR shots you folks take? 

Thanks...Tom.
