Spring Flowers 2013 - Cerco 94mm Quartz Fluorite lens for reflected ultraviolet photography II

Today about some early spring Irises in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was a CERCO 94mm quartz fluorite lens. Light source was the last sunrays of that wonderful spring Sunday. All shots were done at about f5.6. So, on to the results now...
