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.

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.

Color phantasy
For the first composition today I started with cornflowers on a lightbox. I always have liked cornflowers with their typical cornflower blue. With this composition I wanted to show different stages of cornflower development in one image.
Cornflowers © Julian Köpke I also liked very much the yellow of a craspedia globosa that Christa bought this morning. To bring out the colors I decided to install them in my „darkroom studio„. I made the image as a frame average of some 15 exposures, 3s each at f/16 and ISO 800.
Craspedia globosa © Julian Köpke I developed a combination of colours that the garden offered me with the craspedia globosa to create this picture, in which red, blue, yellow and green play a leading role.

Darkroom studio II (glasses)
My darkroom studio is convenient for flower photography and high contrast, especially white. Today I tried out glasses with reflections and a nearly complete homogenous white vase. The only variations are reflections imposed on it from little light leaks of my improvised studio.

Darkroom studio
The darkroom was the centre of analogue photography. In a darkroom were created the copies of a picture on photo paper, which had been planned when shooting with camera and film.
The “digital darkroom” is in a way the continuation of the darkroom from analogue times. Nowadays, the role of the film is taken over by the RAW image. The development of the film was linked to chemistry, intentional light and shadow effects and fine feeling. Each print was unique.
The “digital development” or postprocessing is non-destructive, repeatable and delivers a result, which at least theoretically can be printed as often as desired. In the digital workflow no print is unique anymore.With a dark background and systematic shading of daylight, my photo studio became a darkroom where I could photograph flowers. Exposure times became longer, almost like a long-term exposure at night outside. The saturation of the colors came out surprisingly strong.

Red gerbera and fern © Julian Köpke The creation of a floating cloud with the help of white tulle did not require shading to achieve the effect of a darkroom. As my friend Lorenz mentioned, looking closer you can see nice interference patterns (Newtonian rings). I’m happy with this image idea: the image got two days later a Flickr in explore.

Heidelberg Castle, flowers and flypaper textures
Heidelberg Castle is a landmark. In winter its red color becomes softer. For one winter Frederick V. became king with his home in this castle. After that, Germany sank into the 30 Years War. The castle had been ruined already by fire a couple of years before.
Winter Castle of the Winter King © Julian Köpke The delicacy and dreaminess of a photo is not always the result of intensive digital processing. The ranuncula of the following image hardly needed editing. You can feel it. With a tripod and a 85mm Lensbaby velvet at f/16 I shot this image with really delicate color.
Ranuncula © Julian Köpke The lavish feast is over. Paradise is no more. The king went into exile. We’re staying.

Callas and pink fern leave
For a short time the winter kept us still. Nature offers many motifs, the effect of which depends on the time of the day.

Early spring sun throws light on pampas grass © Julian Köpke Yesterday I came across Calla lilies and rosé-fixed fern at the florists’s. „Expensive“, she told me. But I was already determined wether the many possibilities I had in mind.
Through a chemical process, the fern has received a fixation and new color. That would make it durable for many compositions ….

Red callas in a white vase © Julian Köpke The next day, I combined the callas and the fern to a single composition. With a background the image looks soft and dreamy. This texture puts a kind of patina over the image.

Fibonacci numbers
I wanted to study shadows of simple bodies again today. It all started with an egg last week. The shadow of last week’s egg photo was ring-shaped. I noticed that, but it didn’t bother me. Could the ring shape of the shadow be overcome by skillful selection of light and would the backside of the egg lie entirely in the shadow? This assignment was given to me by a school friend, who himself is a professional photographer.

A neighbor had given me simple bodies, which I placed like an egg on the white background. First of all as a play with form and shadow, where I had to think of the X-ra image of a human hand.
Shadow cast of building blocks on white © Julian Köpke The small wooden blocks were wonderfully colorful. Unfortunately, I didn’t have as many as my imagination would have liked. Arranged in concentric circles, they are delightful to the eyes. At the suggestion of a friend, I arranged, the number of blocks into Fibonacci numbers. The processing of the shadows leads to an exciting image, similar to solarization. Since it is a kind of negative, I named the picture after the impression it makes: „Flow of light“, although in reality it was the shadows of the blocks.

Infinity
Everyone has an idea about infinity. Infinity always confronts us with the question of wether we can see or recognize it at all. Modern mathematics knows that infinite series of numbers may well have a finite limit. The ancient greeks had realized that Achilles will always outrun a tortoise, but they couldn’t prove it. For the solution remained hidden.
Photographing a single, well reflecting steel sphere I got on the surface pointing to my macro lens a distorted image of the surrounding. One can see the tree in our garden, the lens and the tripod of my equipment, even the photographer’s legs are visible. That’s why I think it’s sort of a selfie.
Photographic world on a steel ball © Julian Köpke Immediately, I thought of my friend Harold, who had worked a lot on photographing water drops and who had made a book about the photography of water drops. In the juxtaposition of several water drops the environment is displayed several times side by side in the drops.
Well, this happens as well, if you place two well reflecting steel balls side by side. So far, there is nothing unexpected.
On closer inspection, the opposite sides of the spheres show further images of the surroundings slightly outside the original image, well visible on the tree. These images of the tree become smaller and smaller lying within the circular image of the first reflection.
An infinite series of images in one picture is created by the reflection on the surface of two adjacent steel spheres. As the reflected images become smaller and smaller, the total area of the image is finite. A similar effect is known with water drops as well.
