nfoto Posted July 5, 2013 Share Posted July 5, 2013 Rørslett, B. 2013. Lilium martagon L. (Liliaceae). Martagon Lily. Flowers photographed in visible and ultraviolet light, with fluorescence. http://www.ultraviol...-martagon-lily/ Lilium martagon L.NO: Krøll-liljeSE: KrolliljaDK: Krans-Lilje FI: Varjolilja DE: Türkenbund-Lilie EN: Martagon Lily, Turk's-cap Lily This is a medium tall, to 1 m, perennial species native to Eurasia. It is an ancient ornamental plant and easily naturalised from garden escapes. The typical habitats are meadows or along forest edges. Flowering is in late spring or early summer. The terminal inflorescence carries scattered pendant flowers with reflected tepals and long exserted stamens and style. The dark pink to crimson flowers are fragrant with a slightly unpleasant (to humans) smell to them. They are pollinated by bees and bumblebees. The fragrance becomes more pungent in the evening so it is not unlikely night-active insects also call upon these flowers. Plants collected near Oslo, Norway 4 July 2013 from a fully naturalised population in open deciduous woodland.

Andrea B. Posted July 5, 2013 Share Posted July 5, 2013 This is stunning UVI-VisFL. How do you handle the white balance for Fluorescence fotos ?Do we have a known white fluorescing subject from which to measure ? Link to comment
nfoto Posted July 5, 2013 Author Share Posted July 5, 2013 In this case, what came out from the camera corresponded exactly to what I saw with the naked eye. So I did not in any way change the white balance. LabSphere carries fluorescence standards - at a price. Link to comment
