Electrical Magnification breaks the image into digital data and
transmits it to the brain.
Thermo and Lowlite do not break the image down into data; they merely
magnify the picture and send it along without breaking it into information.
It's the same difference between a film camera with a low f-stop and a video
camera hooked up to an electronic whizzerthingie; both produce a visible image
but the former does it mechanically and the latter electronically.
Thermographics simply invlove sesnors calibrated for a different
spectrum; they do not break the image down but rather look at it from a
different point of view.
