Clematis human and bee vision UV ultraviolet photography

Today about a white clematis flower shot in UV using a Baader U (320-390nm) and a special Bee Vision filter, that allows to map UV as blue into an image so as to simulate what bees can see (UV, Blue, Green). Shot was done using a Cerco 94mm quartz fluorite lens.

Visual light shot (VIS):


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


Simulated Bee Vision (special filter, UV->Blue, Green, Red):


Triptych of those images above:


Note the dark center in the ultraviolet shot which is pertained also in the simulated bee (insect) vision shot.


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

[UV] White Clematis in deep UV - reflected ultraviolet photography

Today about a white Clematis flower shot in deep UV using a special 300-350nm filter. shot was done using a Cerco 94mm quartz fluorite lens. I have previously shot the same Clematis here using my standard Baader U filter.

This first shown UV image here also uses my standardized false UV color normal + high intensity palette:



1) using Baader U whitebalance:


2) different whitebalance (false UV color palette does not match then):



Quite interesting which details this flower reveals.


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

[UV] the world + flower at 300-350nm reflected UV ultraviolet photography

Well, just some first tests trying to have a look at the world at 300-350nm in reflected UV photography. There will be more about the "how, when, what" later here - just look...

and here how my white Clematis flower looks like:

[UV] White Clematis in ultraviolet light using a quartz Focal Reducer lens

More shots using my white Clematis hybride I recently got. Here now using that before presented Spectrometer Quartz Fluorite Achromat f4/84mm lens with a 0.42x quartz Focal Reducer lens to make it a f1.7/35mm lens.

This UV image here also uses my standardized false UV color normal + high intensity palette:



White Clematis in UV:


and in visible light (VIS):


Differential VIS-UV:


The VIS-UV differential clearly shows, that despite the Focal Reducer, still hardly any focus shift is present.

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

[BV] White Clematis in simulated Bee Vision

Same white Clematis hybride flower as shown before in the UV ultraviolet shot, but this time the comparison between normal visible light and simulated bee vison (UV, B, G) as been can only see (ultraviolet, blue, green)

Simulated Bee Vision (UV, B, G):


normal visible light shot:


So obviously also in the simulated bee vision shot it has some dark patterns, as the stamen and stigmata are quite dark, but the flower petals show some UV reflectance. There are also some darker structures visible in these petals.

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

[UV] White Clematis in UV ultraviolet light

We had our regular Spring Flower Market today, so one of the ones I got was a white Clematis hybride. I wondered how that one will look like in reflected ultraviolet light, so here it is, shot through a Baader U filter.

This UV image here also uses my standardized false UV color normal + high intensity palette:



White Clematis in UV:


and in visible light:


So obviously it has some UV pattern, as the stamen and stigmata are quite dark, but the flower petals show some UV reflectance around 380nm. There are also some darker structures visible in these petals.

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