Golden reflected UV ultraviolet photography VII

Today was one of these last sunny October days with golden sunrays in the evening, so I grabbed my UV equipment and went to the park for some more "golden" UV shots. I used the 94mm CERCO quartz fluorite lens for those. Also here my special "golden" processing for these shots has been used.

Quite amazing high resolution this type of UV photography shows.

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

Lens Resolution: Golden reflected UV ultraviolet photography VI

Today I would like to use those recent "golden shots" of autumnal Rudbeckia fulgida leafs to show the different performance of lenses, an older 50mm enlarger lens and the 94mm CERCO quartz fluorite lens. Distance to the leaf was chosen to achieve about matching images. Also here my special "golden" processing for these shots has been used.

CERCO lens:


Here a diptych to make comparison easier, Cerco lens is left:



It gets pretty obvious, that the Cerco lens delivers a much higher resolution and sharpness.

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

Rudbeckia: Golden reflected UV ultraviolet photography V

Today more "golden shots" of an autumnal plant that I had shown before, Rudbeckia fulgida in that case. I was using this time an older 50mm enlarger lens and was playing around with some lighting situations.

I used my special "golden" processing for these autumnal shots that I have also used a few days ago.

Also this was some "artsy" playing with light then my usual documentary work...

Hydrangea: Golden reflected UV ultraviolet photography IV

Today more about those "golden shots" of an autumnal Hydrangea I was presenting the other day. I was using this time my CERCO 94mm quartz fluorite lens and was playing around with some lighting situations.

I used my special "golden" processing for these autumnal Hydrangea shots that I have also used a few days ago.

Also this was some "artsy" playing with light then my usual documentary work and I quite like the results.

X135 UV calibrated f2.8/135mm lens: golden reflected UV ultraviolet photography III

Today I wanted to make the difference visible of those "golden shots" of an autumnal Hydrangea I was presenting the other day. I was using this lens of mine that I have calibrated and used for reflected UV photography a while ago. It has a 5e/5g design and I have posted about it here and here.

I used my special "golden" processing for these autumnal Hydrangea shots that I have used a few days ago. That method I have also used earlier HERE and HERE.

So what you will see is the normal, visible image, the pure reflected UV image and the specially done "golden" shot.

This was some  more "artsy" playing with light then my usual documentary work, but it shoudl still be interesting.

X135 UV calibrated f2.8/135mm lens: golden reflected UV ultraviolet photography II

Today more "golden shots" of an autumnal Hydrangea using this lens of mine that I have calibrated and used for reflected UV photography a while ago. It has a 5e/5g design and I have posted about it here and here.

I again used my special "golden" processing for these autumnal Hydrangea shots that I have used a few days ago. That method I have also used earlier HERE and HERE.

This was some  more "artsy" playing with light then my usual documentary work, but it fits the season very well I thought.

X135 UV calibrated f2.8/135mm lens: golden reflected UV ultraviolet photography

Well, today I dug out this lens of mine that I have calibrated and used for reflected UV photography a while ago. It has a 5e/5g design and I have posted about it here .

So today about UV photography using this lens, executed using one of my last Rudbeckia fulgida flowers. Sunlight was used as a light source.

Oh well and I forgot to mention that I used my special "golden" processing for these autumnal shots, which I have already used HERE and HERE.

and here some autumnal leafs, Hydrangea in that case...




This was more some "artsy" playing with light then my usual documentary work, but still the very prominent UV pattern of that Rudbeckia gets nicely visible.

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

[UV] 340nm Jupiter-U filter for short wave reflected UV (2)

Again more about that new Jupiter-U filter of mine. Shots taken today at the wonderfully blossoming Hermannshof Park, Weinheim, Germany.

All diptychs are presented VIS left, Jupiter-U right:

Gazania xx:


Rhododendron xx:


Pulsatilla vulgaris:


Taraxacum officinale:


That new filter renders quite differently; nicely golden actually.

[UV] 340nm Jupiter-U filter for short wave reflected UV

Today about a new prototype filter of mine. It is called "Jupiter-U" and it is a shorter wave filter than the Baader U (Venus) filter, that I mainly use for reflected UV photography. Its center wavelength is around 340nm.

[click on image to see a larger one]

It is a shorter wave filter (center is 340nm) and its transmission is this, as compared to the Baader (Venus) U filter (red line): Here now some first impression about using the Jupiter-U filter. Target was a Gazania flower. Left: Venus U2, right Jupiter-U: Here VIS comparison shots: Baader-U (Venus U): Jupiter-U: Interesting to note the metallic golden rendering of leafs: Here now using a bred Kalanchoe floower in a quadriptych showing the VIS image (top left), Baader U2 (top right), Jupiter-U (bottom left), special 300-350nm filter (bottom right) and in more detail: If you look closer at the flower center, you'll notice only in the two shorter wave shots on the bottom a variation of reflectance (indicated by changing colors)

[To make things clear, this is a filter for my work, it is not for sale.]

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