Thermal versus Visible Imaging

I recently read an article about the ability of thermal imagers to see what our eyes cannot see. It looked so interesting that I decided to try the experiment myself. Here is what I came up with.

Me in visible light.

Me in long wave infrared.

Now you can't see me in visible light because I'm hiding behind a black plastic trash bag (okay, maybe you can tell I'm behind the bag because of the lighting behind me).

But a black plastic trash bag is not good enough to hide me in long wave infrared.

I've learned that some materials will not hide you as you expect in long-wave infrared.
