Is there a camera that can see through?

SonyDSC-F707 camera has one more function than ordinary cameras. It can shoot at night, with perspective effect and low price.

Not all clothes can see through.

The so-called perspective photography, that is, infrared photography, uses infrared rays to shoot things invisible to the naked eye, especially at night. Its principle is the same as that of ordinary photography, except that infrared photography uses infrared rays invisible to human eyes as lighting source.

Because the wavelength of infrared light is longer than visible light, some materials and textile fabrics reflect less than visible light. This effect is that infrared light passes through the fabric, is reflected by the object under the fabric, and passes through the fabric again. This effectively makes the fabric look translucent, similar to very transparent clothes. Sometimes, in this case, the fabric is almost invisible, forming a nude effect. However, not all clothes can see through. Apart from pure cotton, which is the safest material and cannot be seen by infrared rays, nylon and cotton blended clothes can be seen through (especially in swimming pools and other places, wet clothes are more clear). The perspective of pure nylon and silk materials is above 75%.

Using the perspective function of infrared rays, some objects covered by some objects can be photographed. For example, you can take images of objects under the sand through thin sand. Using ink to shoot altered documents has been widely used in public security criminal investigation.

Sony DSC-F707 is not the only camera that can shoot. In fact, most digital cameras have infrared shooting function, just add an infrared filter.

Perspective invades others' privacy.

If it is only used for family entertainment and not used in public, it does not constitute a crime. However, if it is used to take perspective photos of others, it is illegal and infringes on the privacy and dignity of others; If you take another person's perspective photos for commercial or even other ulterior purposes, it constitutes a crime, and the victim can pursue the other party's legal responsibility.
