Part 6/8:
For these scientific explorations, software processing becomes crucial, primarily because distinguishing between visible and infrared light enhances the clarity of captured data. While commercial solutions, such as specialized blocking filters that transmit infrared light while blocking visible light, can be quite expensive, an innovative workaround involving a black magic marker has been proposed. By applying this marker to glass or plastic placed in front of the camera, Nagel achieved a cost-effective solution to filter the unwanted light, permitting focused infrared observation of heated objects.
