…The Pi NoIR camera module can be used with IR light sources for many applications, including security purposes and animal camera traps. But I wanted to know, if it would be suitable for UV photography (mainly used in foreniscs and flower photography). So I took a Baader-U-filter, which blocks visible light, and an deep-UV light source (365 nm, Labino UV torch UVG3 Midlight) to check this.
Additionally, I made a RGB picture to simulate bee view. Bees do not see red, but they see UV. But since UV is beyond the blue end of the visible light spectrum, the channels have to be shifted. So I put the green channel into the red channel, the blue channel into the green channel and the UV picture in the blue channel. Result is a false-colored photograph, bee view.
I just did a first test with standard settings and a quick edit. Further investigation has to be done. For example I would like to test it without additional light source in bright sunlight and maybe use longer exposure times for UV….
