So what do we see here now? Obviously a mix of UV, visible and IR light. But what produces that halo around that flower? Let's look at the RGB channels to find an answer.
While the green channel seems to have mainly recorded the visible light, since that was the flower part I had focused on....
the red channel seems to have captured some IR and some UV, since the point of sharp focus is quite in the back:
And finally the blue channel seems to have mainly recorded UV light, since the focus also lies way in the back and the center seems to be quite blurred (due to the large aperture used). The UV pattern of the flower gets clearly visible since the tips have strong UV reflectance.
Stay tuned, more will follow on that fascinating subject...
