IR & UV Cut-off Filter Effect

Explanation: The camera which I use in this video is modified to see full spectrum of light, from infrared down to ultraviolet. If I hold now an IR & UV cut-off filter in front of the lens, only visible light reaches the sensor. Therefore the image turns on that place into normal color. Normally every camera with a CMOS sensor would see the world reddish (or in other strange colors), because the sensor is sensitive to a much broader spectrum than the human eye is. Of course no one want’s an image like this
