"Kingdom of Plants" Sir David Attenborough on "Solving the Secrets" in Insect UV Vision (3)

I had reported earlier about that here, but now Kew Gardens has a preview video online on youtube about the forthcoming SKY 3D series "Kingdom of Plants" with Sir David Attenborough on Kew Gardens in 3D stereo as well as an overview on their site including an interview with Sir David.

((quote Sir David from an interview)) Attenborough: Kingdom of Plants 3D. "We wanted to use 3D in time-lapse, so that the plants move," he says. "They look sensational. They always do -- but in 3D, they look absolutely mind-blowing." ((unquote))

The following is a clip from Episode II "Solving the Secrets", that will air Saturday June 2, 2012 at 6pm GMT (7pm CET) on SKY 3D and on SKY ATLANTIC in HD and which I have provided the VIS + UV + UV induced visible fluorescence photography for. Watch from 13.00 onwards about it.


Reference: Kingdom of Plants on imdb

The DVD/BlueRay will be available from July 16, 2012 onwards and may already be preordered at amazon here as DVD and here as Blue Ray (HD) version

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

[UV] Old Achromatic Quartz Fluorite Lens for Ultraviolet Photography (II)

I had mentione before, that I had taken apart some older equipment, as it had some quartz fluorite optics in it. Here now more pictures using it, all closeup shots were done at approx. f11.

Gazania, visual shot:

UV using Jupiter-U filter:


Sanvitalia, visual shot:


UV using Baader-U filter:


UV using Jupiter-U filter:


Not that bad, especially since it has a very small focus shift of only about 1/2mm when shooting macro. I am no having a professional mount made for it.

That Gazania flower I had shot earlier here, which may serve as a comparison.

More about that used quartz fluorite lens is  HERE.

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

[UV] Gazania splendens: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. This time it is about a yellow Gazania splendens flower, that I bought at a nursery (Huben, Ladenburg, Germany)

[click on image to see a larger one]

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



The petal tips of this flower reflect strongly around 365nm (yellow), but also the inside has some surprises, a ring of UV bright white dots (also visible for us humans) set against a very dark petal ground. There are a few more UV colors visible that indicate soem reflection around 385nm (purple) that the longer wave Baader-U filter as well as a to a lesser amount also the Jupiter-U is able to reveal.

Here more details of that flower (VIS, Baader-U, Jupiter-U in that sequence):







A very pretty species and surely attractive to its pollinating bees!


Might it be that the unusual high UV reflection of its leafs aims at protecting it from too much UV radiation?

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

[UV] Sedum flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. This time it is about a yellow Sedum spathulifolium flower, that I bought at a nursery (Huben, Ladenburg, Germany)

[click on image to see a larger one]

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



Although this one has an overall 365nm main reflection, inside that flower is some long wave (around 385nm I'd say) UV reflection visible, that only the longer wave Baader-U filter is able to reveal.

Here details of that flower...

using the Baader-U filter:


and the Jupiter-U:


Overall this interesting plant looks like this (VIS, Baader-U, Jupiter-U)







Might it be that the unusual high UV reflection of its leafs aims at protecting it from too much UV radiation? Here how that looks like in closeup (VIS / UV):



Mother nature has quite good ideas!


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

[UV] Cinquefoil or Potentilla flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. Also those shots were taken at the wonderfully blossoming Hermannshof, Weinheim, Germany. This time it is about a yellow Potentilla flower.

[click on image to see a larger one]

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



Potentilla has a very strong UV reflection around 365nm, so much that it actually overpowers all around.

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

[UV] bog-bean flower Menyanthes trifoliata: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. Also those shots were taken at the wonderfully blossoming Hermannshof Park, Weinheim, Germany. This time it is about a white marshland bog-bean flower Menyanthes trifoliata.

[click on image to see a larger one]

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



It is UV reflective but quite long wave and does so around 385nm.

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

[UV] Bidens flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. This time it is about a Bidens ferulifolia flower.

[click on image to see a larger one]

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



The separating greenish ring between the UV bright tip and the UV dark petal part captured my attention and needs further research.

Bidens is one of my "standard" UV photography targets, as it has a very prominent bright UV petal tip reflection:



It peaks quite prominently around 365nm which my spectral reflection measurement clearly has proven.
