Why can an infrared camera see through and what is its principle? How not to be perspective?

Infrared perspective shooting is the use of infrared rays to shoot scenes invisible to the naked eye, especially in a completely dark environment. Its principle is basically the same as that of ordinary shooting, the only difference is that infrared night shooting takes infrared rays invisible to the naked eye as the lighting source to shoot. ?

Because the wavelength of infrared light is longer than visible light, it can be reflected by some materials or textile fabrics that are less than visible light. In this way, infrared rays can penetrate clothes made of certain materials, reach objects hidden under the clothes (such as the body) and reflect back, thus making the clothes translucent and making the body look like a nude.

However, not all clothes can be seen through infrared light. Cotton-padded jacket cannot be penetrated by infrared rays, so it is the safest. Nylon and cotton blended fabrics may be seen through, especially wet clothes in swimming pools and other places, and the perspective is clearer.

Precautionary measures for infrared cameras;

The first trick: don't take photos with people on the street at will; When going out, don't easily agree to take photos with people, because infrared camera perspective shooting needs a certain distance, as long as the people who sneak shots are not very close, it is difficult to take a perspective effect.

The second measure: try to change to cotton clothes; Cotton-padded jacket can't pass infrared rays. If the camera touches the cotton clothes, there is no place for it. Therefore, if you want to prevent "sneak shots", you can put on cotton underwear and coat.

The third measure: pay more attention to strangers who take pictures with cameras around them; Mm playing outside should pay more attention to strangers with cameras around them and try to keep a certain distance when meeting.

The fourth measure: try to wear red or green clothes to the streets; Wearing red or green clothes has a certain influence on the penetration ability of infrared rays, which can effectively prevent being photographed, and even if it is accidentally photographed, it will not achieve an approximate nude effect.
