I have set up a studio of black surfaces where the light falls on my objects from above. All distractions that could interfere with the view disappear as if by magic. There is only the object.
Every ray of light that does not fall directly into the eye remains invisible. Concentrated light such as laser beams is made visible by introducing vapour from CO2 into the beam path, for example, which provides the necessary deflection into the eye or a photographic lens.
For the same reason, light from above escapes the eye of the observer or the photographic lens when viewed horizontally. Only an object deflects the light from above in the direction of the eye or the photographic lens. This is essentially a reflection. Transmission of reflected light can also occur with objects that are transparent. This is the case, for example, with fine petals or glass. Both phenomena, reflection and transmission, are of great aesthetic appeal and therefore of photographic interest.
In the end, there is only the object – or composition. Photographing colored flowers in a dark room has the effect of an apparition emerging from the darkness. And the picture immediately makes you think. These pictures made me think of a quote by Henri Poincaré, whose exact source („The value of science“?) I have unfortunately not found: „A thought is like a flash of lightning in the middle of a long night, but it is everything“.

Transparencies
HDR photography of flowers with a light box creates the illusion of translucency, which is very attractive in itself. By fusing X-ray light and visible light in flower photography, one expands the photographic possibilities by reproducing the inner structures of the photographed plants or objects. The illusion of translucence is enhanced by the physical transparency of X-ray light. Even photographically non-transparent objects can be given the illusion of transparency by fusing X-ray light and visible light.
A publication by the dPunkt publishing house in „foto espresso“ gave me the opportunity to present this idea in the May 2023 issue.

Lilies of the Valley
Yesterday I came across a piece of music through a noble advertising trailer of a French watch company with the wonderful actors Catherine Deneuve and Rami Malek directed by Guy Ritchie. I was almost magically drawn to the film because there was a time when I lived in Paris.
But the most exciting thing was the soundtrack „Lilies of The Valley“, which exuded such an incredible lightness. I hadn’t heard of the composer Jun Myiake before, but I did know Arto Lindsay, who added his inimitable vocals. Perhaps one cannot leave the cosmos of one’s own taste.
That’s why I quickly set off to get some lilies in town. They were to be white lilies, of which I could only get two. Red lilies in all stages of blossoming I then allowed myself to enjoy. So I took some pictures with a mixed bouquet of paradisiacal blooming lilies.

Spring Dance of Tulips
Today the sun shone warmly, almost too warm for a day in mid-February. A few tulips given as gifts were getting older in the vase and one started to hang its head. They had delighted us with their colourfulness for many days.
So I decided to do a photo series with tulips on my lightbox.
Tulips are best suited for scenic representations because they look like a human person against a light background. Dance is the most obvious association I have then. The leaves become whirling arms. The flower is the head. The legs are not really needed.

Amaryllis
The format for recording an image can be very variable when fusion imaging is involved. In the example below, the image on the left is taken with a Phase One IQ4. The sensor size is 44mm x 55mm. The X-ray image on the right was taken with a Hologic mammography system with a detector size of 24cm x 30cm. The aspect ratio of both images is 4:5. The pixel size of the IQ4 is 6.5µm, the pixel of the mammography is 70µm long. Nevertheless, the images can be fused well.

Amaryllis X-ray mammography photogram © Julian Köpke I added some texture to the fusion image because it made it more appealing. Due to the fusion of the image from „visible light“ and the image with „X-ray light“, the definition of whether it is a medium format image or a large format image is no longer meaningfully applicable. It is simply an image.

White and purple orchid
My LED ceiling light, which I use as a light box for flower photography, can be dimmed and the color temperature is adjustable. The cold and extremely bright light can be tamed and turned into faint, warm light. Together with my tent of linen, I manage to control the light.
With LiveView, the composition is created and the focus is worked out. The camera is controlled by cable connection via laptop (tethered shooting) and the recordings are made with mirror triggering. The colors become better and the impression of the picture more natural and vivid.

Sunny day with spring character
A sunny day in winter without training or weekend obligations: we can let ourselves drift a little. The Hermannshof in Weinheim with its botanical garden attracts many visitors, especially those with cameras. Many kneel or lie down on the floor to gain a beautiful perspective. You don’t notice dirty trousers. Rather, trousers like that ennobles the wearer.
First light welcomes a crocus when the sun shines abundantly and the joy of photographing is written on the face of all visitors.

It took me a while to recognize three legs and a shaved fur on her right hip. Due to a chondrosarcoma her owner had decided to have an operation on the dog. She did quite well, as far as a human may understand.

Floral experiments
Changing colors in flowers are attractive, especially if you approach them closely. A group of 3 flowers looks like a communicative group. With targeted overexposure and instant images on the laptop, the compositional decision is easier and the colors become more picturesque, without too much processing with the computer.

Red and yellow gerbera © Julian Köpke Photography of flowers in a vase in an exposure series (HDR) is complicated by their light sensitivity, which causes a change of position in short time scales. Plants constantly rearrange their leaves and blossoms. This results in blurring, which can be compensated for e. g. by repeating the shot series, shorter exposure time series or tools for aligning the images. Or you can do your image without HDR, because the dynamic range of the camera data is sufficient.

The light should be relatively bright, but does not have to be fully homogeneous. The heat of the light does not matter, it is adjusted using RAW format in post-processing. More informations about this method see web-pages of Harold Davis, who invented this method.

Turn of the year
The most surprising thing this year was the selection of many of my pictures in the Flickr Explore stream. My best picture in 2021 is again a black and white, this time of the Bernese Alps with a view of the mountain chain Eiger, Mönch and Jungfrau. The picture was taken on the Schilthorn when I fled the permanent James Bond exhibition.

We drove to the Black Forest and hoped for snow to cool off. The snow did not come immediately and a red dawn on January 2nd seemed dangerous and not calming.

Snowfall at abandoned mill © Julian Köpke With the help of some tips from a photographer friend I was in school with a long time ago, I tried to improve my photographic technique and post-processing. This includes the trick of placing a piece of newspaper in the sharpness plane of the lens in order to speed up the focus. Very effective.

Amaryllis
I’ve been experimenting with macro shots or portraits that have a black background. For this I reduce the roomlight with the help of the electric shutters, the exposure time and the ISO value are increased. To improve the quality of the shots, I also used the method of frame averaging to get the RAW image with a single shot and sufficient quality.
Yesterday I was able to admire my friend Harold in a tutorial how he created LowKey HDR macro photographs using an exposure series from -4 EV to 0 EV. I tried all paths today with my Amaryllis, which I had bought 2 days ago.

Through the systematic under-exposure one can create a beautiful black background. The use of a surface spotlight creates transparencies with HighKey effect.
