How to debug Nikon D40D60 plus infrared filter to achieve the best effect?

Infrared photography? Ordinary cameras don't seem to be possible, so don't rush to buy filters. Generally, digital cameras have to remove a filter in front of the CCD (note that it is a square filter inside the camera, not a filter outside the lens) to take infrared photography. Some cameras (such as Sony's) have their own infrared photography function. In fact, a mechanical part is added to this filter, and the filter is removed when using the infrared function. Many people use outdated digital cameras and transform them into special machines for infrared photography. Without D60, it is basically impossible, so it is more complicated and not suitable for transformation.

The colors taken by infrared photography are very strange, both monochromatic and colored, which can penetrate some thin objects and have night vision function. If you have to shoot, you can only buy this model of night vision infrared mirror, and maybe you can add a camera at the back.
