Bidens Butterfly Vision 3D Stereoscopic - 2shot Method

Here a test shot today with a [Bidens ferulifolia flower. This time using a different 2 shot stereo method. This also is for cross eye viewing.

Simulated butterfly vision (UV=blue) 

and a close-up shot: 

The following shots now uses the UV-Rodagon 105mm with even higher resolution, 

so even that fuzz on top of that flower gets visible in 3D: 

This method obviously delivers much higher resolution as two full size images are being used, but works only with static objects of course.


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

Bidens Butterfly Vision - 3D Stereoscopic

Here some tests of today with a Bidens ferulifolia flower. I thought I should add another dimension - 3D (stereoscopic) vision. This is for crossed eyed viewing (i.e. R-L are reversed)

This is some early testing, as a UV beamsplitter is a tricky thing to get to work.

Here another one with a "guest"...
 

... and a (very) 3D flower portrait.

Creeping Zinnia - UV pattern when "bee ready"?

I noticed that on a Creeping Zinnia young flowers (in front) do not show a prominent UV pattern, but others do (the one in the back), which are ready for pollination.

I wonder if that UV pattern would disappear when pollination has successfully happened? I guess that would be worth some scientific study (or maybe I should do it?)...

Bidens - how she does it (simulated butterfly vision)

Bidens never ceases to amaze me...

The far-away white/yellow guide for insects is completely invisible for us. Then the blue UV reflection of the "husk" protecting the stamen + pollen just before it opens up to reveal the pollen, yet at the same time acting as a guide for the insects when they are close enough (insects only see sharp close-up).

These are my personal assumptions btw. and I would think it would be worth working on that scientifically...maybe I should. Isn't nature simply amazing....?!

Gazania - how she does it (butterfly vision simulated)

Already last year I showed some images of a south african Gazania flower. I was wondering how she attracts insects, so I used my bee / butterfly vision filter and took some shots. Here the astonishing results.

Butterfly vision (simulated) shot (UV=blue) 


Well, I guess now we know what she "does", the pollen lights up strongly around the flower petals in the central part. They have a quite strong UV reflectance also, so like a concentrated ray of light shoots out of that flower to attract insects!

Potentilla multispectral

Well, also some flowers of the genus Potentilla (Sulfur Cinquefoil) has a very interesting pattern which only shows in ultraviolet, so I took a chance to shoot that interesting little flower using a UV-Planar 4/60mm lens and various filters /  lightsources.
