Apache beggarticks - Bidens ferulifolia in deep reflected ultraviolet photography VI

Today more shots - but developed from RAW files using Capture One PRO - of a spring flower I have written about before, Apache beggarticks - Bidens ferulifolia in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my deeper into UV reaching Jupiter-U and Saturn-U filters. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f5.6.

Visible light image:
 

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
 

UV image using Jupiter-U filter (approx. 280-385nm, effective peak approx. 365nm):
 

UV image using Saturn-U filter (approx. 300-350nm, effective peak approx. 325nm):
 

Quadtriptych of the above:
 


Bidens has a strong visible UV pattern, its petal tips are UV bright around 365nm, its center is quite UV dark, so this gets even nicer visible for deep UV recording developed from RAW files.


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

Oregano - Origanum sp. flower in reflected UV ultraviolet photography and simulated bee vision

Here today shots of the attractive Oregano - Origanum sp. nice smelling spring flower which also is a wonderful cooking herb, not just for pizza. Shots were done aside from visible photography in reflected ultraviolet using Baader-U and the deeper reaching Jupiter-U filter, as well as in simulated bee vision using my XBV filter. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Simulated bee vision image using experimental XBV filter:  

Quadriptych of the above images:  


This Oregano inflorescence has a UV pattern, its little petals reflect around 380nm when fresh and this disppears when the flower wilts, which shows especially well in the shorter wave Jupiter-U shot and all that gets nicely visible.

Full Moon over Weinheim Castle: multispectral photography

Here today shots of the full moon over Windeck castle here in my hometown Weinheim Germany. Shots were done aside from visible photography in reflected ultraviolet using Baader-U filter. Lens used was my CERCO 94mm quartz fluorite lens. Light source was moonlight resp. the castle lighting system. All shots were done at approx. f8. No later whitebalancing was done, pictures straight out of the camera.
