On the perspective of infrared filter

Infrared photography is often associated with perspective.

The so-called perspective is because infrared light can pass through some substances that are not very transparent to visible light. The premise is that there is enough infrared light, the outer layer can penetrate, and the infrared filter filters out all visible light interference.

For example, the best example is the dark protective film on the infrared remote control, with a filter in the sun to see how transparent it is.

This is the truth of some famous perspective photography of 0LuxNightShotCamcoder.

However, perspective photography not only requires very high filters, but also magnifies weak light. Digital cameras do not have the above-mentioned brightness enhancement function, and the perspective effect is very limited.
