Many infrared cameras on Taobao are modified, and infrared photographic cameras are sold. Does the near infrared camera have to be equipped with a filter?

There are two ways to replace the infrared machine:

One is to replace the low-pass filter in front of CCD with infrared filter. Usually the wavelength of this filter is not very long, and then an infrared filter is usually added to the lens when shooting.

The other is simply to add an infrared filter to the lens, and the filter with different wavelengths has different effects. Usually the first method is more effective, and the latter method is more economical.

Either way, the possibility of hand-held shooting is not high, because the light is insufficient and the shutter drops badly, so a tripod is needed. In addition, to be effective, it is advisable to shoot when the sun is sunny in summer, such as when the sun is high at noon. In addition, PS is necessary, and infrared photos cannot be taken without PS.

I added a filter to my Pentax Q to shoot infrared rays. I lost interest after playing for a few days. Not expensive. If you want to play, I suggest you start with the filter. If you are really interested, change the machine.
