Rudbeckia hirta on my balcony multispectral

Rudbeckia hirta on our balcony has wonderful flowers again this year - here it is in human vision, reflected UV, simulated bee and butterfly vision (quadriptych is left to right, top to bottom).

All shot using a multispectral converted Panasonic GH4 with the trusted UV-Nikkor 4.5/105mm lens at f11 using a modified Xenon Studio flash as well as some special filters.

Best seen with "lights out" ;-)

Each has a different “presence”.

Any idea why reflected UV, the second one looks so 3 dimensional!

UV photography has on average about 1.7x resolution as compared to the visible light image - hence so much more details visible.
The BG is the blackest material available for sale today, from Japan a nano fiber coated material - which is also rather black in UV
(which mos other black materials or paints are NOT - except Semple 3.0 paint).

Could I add resolution by using a UV capable lens and processing that component separately to add as a layer in Photoshop?

If the separated UV component is converted to a visible color temperature, that might be a fine addition to increase apparent resolution of select parts of objects, like the compound eye of a fly, the markings of a the or the veins on leaves!

YES, BUT only if that lens has NO FOCUS SHIFT, otherwise the images would not match!
So you would need a very well corrected quartz-fluorite lens like the UV-Nikkor or similar.
