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.
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.
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.
A curtain over the illuminated background behind the focal plane creates an effect reminiscent of nebulae in the night sky.
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 center of a Gerbera blossom is richly structured. Due to the high resolution of the camera back (150 MP), it is possible to crop out the center still in good resolution.
The transparent representation of the petals is achieved by using a light box. 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.
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.
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.
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.
A photograph of a glass in a more documentary style is the following. The representation of the glass cutting is realistic. The stem out of the focal plane is appropriate for the focus of the photograph.
The combination of black and green thrilled me in the composition with traditional wine glasses for regional white wine. Unexpectedly, I got some copper allusions with some warmth in the transparent glass.
A more cool representation is the following composition with more glasses, including a tasting glass for Whisky. Is it the morning after a roaring party ? No leftovers can be seen so far …
A more detailed view ist the following photograph, which is more on the warm side. The glasses get a copper-like appearance.
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.
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.
The soft variations of light and shadow fit well to a soft vetch.
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.
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.
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.
Shortly after, the snow has said goodbye to us. Still very, very cold cloudless nights, more and more often glorious sunny days let you catch your breath.
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 ….
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.
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.
The shadow looks better today, with a little help from Photoshop.
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.
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.
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.
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.
