Flowers were photographed near Bensheim, Germany 24 May 2013. 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 100, 1/60s.Image reference: NCH_P1080687130524 UV-image, Baader U-filter 2”, ISO 400, 2,5s, sunlightImage reference: NCH_P1080688130524 “simulated bee-colours”: composite image of the UV image (-> blue) (grayscale conversion) 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_P1080687_RGB_UV_bw130526 The petals have a quite strong UV-reflexion while the stamina are UV-dark. From the channels used for the bee-colours, UV and blue are most dominant which creates the bee-turquois. [Published: 26 May 2013] Link to comment
