[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:


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

[UV] Spring flowers in UV ultraviolet light - yellow overdose

Just the perfect sunny spring day today and a chance to capture some yellow flowers, that also come out yellow in UV in my standardized false color scheme - as they reflect UV around 360nm. I'm showing matched image pairs (VIS, UV).

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



1) Oregon grape (Mahonia aquifolium)




2) Dandelion (Taraxacum officinale) and Daisy (Bellis perennis) and Ground Ivy (Glechoma hederacea)




3)Lesser Celandine (Ranunculus ficaria)




4) Yellow Anemone (Anemone ranunculoides)




5) Dandelion (Taraxacum officinale)




6) Wild Tulip (Tulipa xx) and Pheasant's Eye (Adonis vernalis)




Pretty amazing what nature does to attract pollinators!


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

[UV] Succulent flower Carpobrotus edulis in UV ultraviolet light

Here is a succulent flower (most likely Carpobrotus edulis) that was bought for our balcony. Shot in reflected ultraviolet light using the Baader U filter.

VIS image:


Pretty interesting to see the innards of that flower lit up very brightly in UV, surrounded by UV dark petals - that must make quite an attractive target for pollinators.

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

[UV] Barlow lens to eliminate vignetting when shooting in reflected UV

Today about using getting rid of vignetting when shooting reflected UV light and using older lenses. The rescue used here is a quartz Balow lens.

UV test image, left without and right with quartz Barlow lens:


White Clematis in UV:


That used Barlow lens enlarged the projected image by a factor of 1.4x, hence letting the vignetting disappear beyond the sensor borders.

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

[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:

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...
