Bidens: human vision vs simulated bee vison II

Today about a Bidens ferulifolia flower, one of my fav UV "models" shot outside using sunlight. Shots were done in normal human vision, in UV using the Baader-U filter as well as in simulated bee vision using my various XBV filters respectively, that simulate insect / bee vision in just one shot.

Visual shot:


Simulated bee vison using XBV3 filter:


Simulated bee vison using XBV2 filter:


Simulated bee vison using XBV6 filter:


UV using Baader-U filter:


This flower has a very prominent UV pattern (365nm peak) on its UV-bright petal tips, that's why I like it as a standard test target a lot.


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

Bidens: human vision vs simulated bee vison

This is about a Bidens ferulifolia flower, one of my fav UV "models". I took some shots, in normal human vision, in UV using the Baader-U and Jupiter-U filter as well as in simulated bee vision using my various XBV filters respectively, that simulate insect / bee vision in just one shot.

Double Diptych : Bidens - Sanvitalia VIS vs Bee Vision

A diptych today, comprising a Bidens ferulifolia and Sanvitalia procumbens flower side-a-side in normal VIS and a bee vision (as seen through my one-shot propriatory XBV3 filter).

Bidens ferulifolia, various filters + light sources

Well, another nice target for UV photographic experiments is Bidens ferulifolia, the variety "Peters's Surprise".

Equipment used was: Nikon D70 (unmodified), ISO400, f5.6-8, 1/160sec, old 100mm enlarger lens.

VIS using XCUT2 filter (400-650nm):


UV using Baader U-filter (310-390nm) - synthetic DOF:


XUVIR multispectral filter (300-1000nm), UV Flash:


UV induced fluorescence using XCUT2 filter (400-650nm), UV flash:

So, as you may see, a variety of results also that flower shows us.

P.S.: if you wonder what "synthetic DOF" means, I used "stacking" to increase the DOF artificially.

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