Nature in Brilliant Colour Exhibit, ROM Toronto

I have been asked by the Royal Ontario Museum (ROM), Queens Park, Toronto Canada for permission to exhibit a series of images to simulate the vision of butterflies at their forthcoming exhibit "Nature in Brilliant Colour " which is a travelling exhibit originally developed by the Field Museum Chicago. The exhibition will run from 14 December 2024 to 17 August 2025.

For that exhibit I chose images of a Rudbeckia hirta flower Black Eyed Susan - Rudbeckia hirta which I had shot using visible and reflected ultraviolet photography. All shots were then done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated animal vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash.

I chose Rudbeckia hirts, as it has a strong UV pattern, its petal tips are UV bright around 365nm, but its center is quite UV dark, so this gets quite nicely visible, hence why I used this flower here to simulate butterfly vision.

Simple question since I'm not into UV photography at all: As far as understand the Baader filter mainly transmits around 370nm (+/- 50nm), exluding/blocking everything else in the 200-1200nm range. How dou get the coloured "UV" image then?

THX for an explanation Wink
