[UV] Caltha palustris (Buttercup) flower in deep UV reflected ultraviolet photography

Today about a Caltha palustris (Buttercup, Marsh Marigold) spring 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.

The UV images here also uses my standardized false UV color normal + high intensity palette:



Visual light shot (VIS):


Ultraviolet light (Baader U filter, 320-390nm):


Ultraviolet light (special filter, 300-350nm):


Ultraviolet light (special filter, 300-350nm, different whitebalance):


It was too windy for that special filter, so I had to use high ISO, so the quality is not my usual one.

So exploring the world beyond 350nm goes on...


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