After some hiatus caused by a move to the French border here in Germany, here my first multispectral work:
This is of a long blooming, perennial flower, the Cliff maids - Lewisia cotyledon in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were 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 bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight and some UV LED help.
Lewisia has a visible to bees and butterflies UV pattern, its petal tips are UV bright around 385nm, its center is UV dark, so this gets quite nicely visible, also in simulated butterfly and bee vision.
But there is also a highly UV reflective area visible, formed by those shiny petals which is especially quite visible in UV!
