What effect can I get by taking a portrait with an infrared filter?

Infrared filter, if it is 760 or 850, is black and white imaging, because the band is above 760nm, which is infrared light.

There is some visible light at 720nm, and the imaging is also beautiful.

The following is the effect of infrared 720 shot by photographer and Li in Australia.
