A multispectral example using Mexican Zinnia

Just a few quick shots today using the UV Rodagon 60mm for multispectral analysis in visual light, UV, UV fluorescence and IR. As usual I used a Nikon D70, SB-140 flash w. SW-5UV filter, UV Rodagon 60mm, Baader 2" U- and UV/IR Cut- filter (for UV and UV fluorescence), B+W 092 filter (for IR).

Target was a Mexican Zinna; the little flower head is about 12mm in diameter, i.e. magnification was about 0.5x which still is within the 
design range of that lens. Here now the visual shot:




The UV shot reveals that special pattern this flower shows:




UV fluorescence shows the intensive light of the pollen:




IR finally looks quite transparent:




Quite interesting how the very same flower appears in different wavebands!

Stay tuned, more will follow on that fascinating subject...
