> glowing because they are alive...well you can take IR of a corpse. you're just looking at different reflectance based on what the surface reflects into the IR spectrum. photography is based mostly on reflectance except where the subject emits light. IR film doesn't capture that.

I've noticed that the glow is not always IR glow but instead
the defocusing of the IR wavelenghts. Such that if you focus 
the visible spectrum, the IR can be so far out of focus it
appears to be glowing. Does anyone know how to translate
circles of confusion into spectral ranges?
