Well, also some flowers of the genus Potentilla (Sulfur Cinquefoil) has a very interesting pattern which only shows in ultraviolet, so I took a chance to shoot that interesting little flower using a UV-Planar 4/60mm lens and various filters / lightsources.

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