the data still needs to be there. That's why it requires a photo with flash and a thin white shirt, the skin can be seen best through the shirt that way. Then it's only a matter of playing with levels and contrast to get the white to match up with the surrounding colors/just be less overbearingly bright so the color is easier to view
[QUOTE=johan_sm;25368669]My old videocamera could see IR from my remote without requiring any mods.[/QUOTE]
after a website or three began exploiting the at-the-beach uses of IR light (infringing people's personal rights much like up-skirt voyeurs), camera manufacturers began placing filter lenses inside the camera that would prevent IR from being seen by the sensor. It looks like a little plastic cube in between the actual lens-shaped-lenses and the sensor.
The Black & white Infrared preset is missing to me.
Here are two other "x-ray" techniques for Photoshop, if anybody cares.

That would be nothing new.
To my knowledge not an awful lot of the materials you come across in every day life REFLECT x-rays (which is what is necessary in order to see things).
The way an x-ray works is that on one side you have a detector, and on the other side some x-ray source. X-ray source blasts x-rays through you and the dense shit like bone stops x-rays getting through, while the less dense shit, like muscle, fat, organs, all of that squishy stuff let's x-rays go right through you to the other side and hit the detector. Detector builds an image of your bones using the x-rays that DIDN'T get through.
Because x-rays don't too readily REFLECT if you wanted to photograph shit using x-rays... well, you'd need a detector on the other side (like when gas pipes are surveyed and shit sometimes).
Not to mention it's not very safe to go around blasting people with highly ionising radiation. That shit DOES cause cancer.
Different wavelengths can penetrate materials of different density.
So yes. It's possible, but nothing fap-worthy.
