Nico Posted June 25, 2013 Share Posted June 25, 2013 Chalwatzis, N. 2013. Cichorium intybus L. (Asteraceae). Common Chicory. Flowers photographed in visible and ultraviolet light, including simulated bee colours. http://www.ultraviol...common-chicory/ DE: Gemeine Wegwarte, Zichorie EN: Common chicory, Blue Daisy, Blue Dandelion This is the wild form of the vegetable chicory. It is common along streets and paths. Flowers were photographed near Bensheim, Germany 15 October 2012. All images were taken with a broadband-modified Panasonic Lumix G1 and the EL-Nikkor 80mm/f5.6 at f8. Visible light image with IR-neutralisation-filter ND (Optic Makario), ISO 100image reference: NCH_P1060273_120918 UV-image, Baader U-filter 2”, ISO 400, sunlightimage reference: NCH_P1060276_120918 “simulated bee-colours”: composite image of the greyscale converted UV image (-> blue) and the blue (-> green) and green (-> red) channel of the visible light image. The goal of this is to mimic the spectrum that bees and other insect-pollinators can see.image reference: NCH_P1060275_RGB_sw_121015 Interestingly, the petals that appear blue with white centre parts in visible light are UV-dark in the center and get UV-brighter towards the tips. The filaments are also very UV-dark.The simulated bee colours show a prominent bee-yellow centre that guides the pollinators. [published: 25 June 2013] Link to comment
nfoto Posted June 25, 2013 Share Posted June 25, 2013 I have similar UV captures. So move them down a notch or two on the prioritised to-do list. Link to comment
