I have previously shown here, how the world looks like at 300-350nm. Now more how a flower (Phalaenopsis in that case) looks like at 300-350nm in reflected UV photography in comparison to using a Baader U filter (320-390nm) and in normal visible light.

UV: Baader U filter:
In the last 300-350nm shot, the colors denote: yellowish green is 330-345nm, blue is <325nm.
These triptychs will show the differences side-a-side:
The shorter the waveband used gets, the more details the flowers reveals.
Stay tuned, more will follow on that fascinating subject...
