    Sempervivum "hens and chicks" multispectral

    My Sempervivum ("hen and chicks") plants were flowering due to that excellent hot weather we currentlyhave here in southwest of Germany. Took photos in reflected UV and simulated bee and butterfly vision using an UV-Nikkor 105mm and a modified studio flash. Just amazing how good this lens...

    Bidens VIS-UV live

    Amazing that dark "bullseye" UV-pattern bees and butterflies can see as a landing platform, but we humans cannot... There have been scientific experiments done (Prof. em. Klaus Lunau, Düsseldorf, Germany) which prove that bees land on a flower petal and then always crawl to find the UV-dark...
