Today some shots of an early spring flower I have written about before, a Rock tulip - (Tulipa saxatilis "Lilac Wonder") (often wrongly labeled T. bakeri) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at about f8.

Quadriptych human vision, UV, sim. butterfly vision, sim. bee vision (left to right, top to bottom):
This rock tulip has a not so strongly visible UV pattern, its petals are UV bright, and this gets quite nicely visible in these close-ups.
Stay tuned, more will follow on that fascinating subject...

Cretian Rock Tulip - Tulipa saxatilis with crab spider in reflected ultraviolet photography and simulated bee vision
Today shots of a Cretian Rock Tulip - Tulipa saxatilis with a crab spider sitting in it, just having its lunch, in reflected ultraviolet photography, using my "work horse" UV filter, the Baader-U filter, as well as my XBV6 filter for simulated bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych of human vision, UV and simulated bee vision (left to right):
This tulip has a rather subtle UV pattern, tricky with inside UV reflective petals, which reflect UV rather well around 380nm using a very shiny petal surface and quite classic, an UV dark center creating a bullseye pattern. Surpisingly the spider also appears quite well in UV and has UV bright spots on it - maybe to attract its prey? Only nature knows...
I have written about this Tulip previously HERE and about the crab spider HERE
Stay tuned, more will follow on that fascinating subject...

Rock tulip - Tulipa saxatilis in reflected ultraviolet photography, simulated bee and butterfly vision II
Today some close-ups of an early spring flower I have written about before, a Rock tulip - (Tulipa saxatilis "Lilac Wonder") (often wrongly labeled T. bakeri) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.
