Simply Brilliant! Thank you...

[@B30pt87]

YES! Yes yes yes! Awesome! All the words.

Just bought a black light.....now to explore ❤😊

[@DadofScience]

I love this. Brilliant stuff, Altay. I went to the trouble of converting a cheap AUD2 LED flashlight to UV to explore my own backyard and surrounds beyond the visible spectrum. Very much worth it. If this sort of thing is of interest to people I'd gladly make a how-to video for those who want to try it with a much lower cost to entry to get started. :)

Lichen this video quite a lot!

Lichen! This reminds me of the aqueducts in the island of Sao Miguel of the Azores. The aqueducts are dominated by the lichen. I feel like you'll have a blast taking photos of these. I don't think anyone know who built the aqueducts so that'll add to the mysteriousness.

Very exciting. What are the preferred UV wavelengths for terrestrial & marine environments please ?

[@FlameForgedSoul]

Acknowledged.
