Today about a Bidens ferulifolia flower shot in deep UV using a Baader U (320-390nm) and a special 300-350nm filter. shot was done using a Cerco 94mm quartz fluorite lens. I have previously shot the same type Bidens here using my standard Baader U filter.

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