    Sadness never ends, but luck

    Tulips have become an attraction to me. For a long time I found them extremely boring and meaningless. That has changed over many years. Should I have become older because of that ?

    We also have many tulips in our garden. A group of red tulips at the edge of then planted tomato bed is particularly beautiful. But is this beauty also photographicable ?

    The beauty in a vase is the epitome of transience. In the meantime, changing light conditions trigger a feeling of tension and happiness in me. This bouquet of tulips has been staying with us for a week now.

    With my iPhone I took a shot in our living room. Filter apps help me to get a presentable result.

    Today I wanted to try out the same light with the tulips, which spoils my eyes every day with the orchids.

    As one can see, our tulips in the living room get already weaker. They are old guys now. Fresh water doesn’t really help. There is no light at the end of the tunnel. How sad is that.

  • flowers,  Long time exposure

    Time fusion tulips

    Inspired by a photography of german photographer Michael Wesely, I tried to superimpose the movements of orange tulips in a white vase to create an equivalent to a longtime exposure image. A longtime exposure with 3 or 4 days exposure time was unfortunately not possible for me. Therefore I took 35 pictures with my camera at irregular intervals dictated by occupational requirements whose pixels were to be averaged. Here 4 examples of the highly active flowers in a vase:

    Each RAW image has a file size of 125 MB, after RAW conversion this was 580 MB per image as TIF. The entire stack had a size of 21,5 GB. The image of the average then becomes 580 MB again. The pure mean value image was interesting to me but not exciting. Therefore I took this image and layered in parts of original images. The result became convincing:

  • X-Ray

    Fusion X-ray of tulips

    Fusion imaging is beauty made of composite X-ray images and HDR images on a light box. The primary question is what energy fits best for flowers. To my experience 40 kV is often suitable. But: the proof of the pudding is in the eating.

    Mammography systems start e.g. from 20 kV and reach 39 kV. The sensor is up to 24cm x 30cm. Conventional systems start from 40 kV and reach 125 kV. The sensor is up to 43cm x 43cm what makes them more attractive to floral compositions.

    The higher resolution and the lower energies of a mammography will suit better for transparent objects. But the spatial limit of a composition (which is 24cm x 30cm) might put hard restrictions on the artist.

    Floral compositions have more creative space with a bigger sensor. But the X-ray tube starts with 40 kV and this might lead to overexposure of tender structures.

    Thus I performed today more than ten compositions to study this relation.

    After four exposure of three tulips I found this composition with four dense blossoms attractive to go further. The composition might somehow resemble to a sketch of three angels. The image is nice due to very soft edges of their „wings“, technically blown out portions in the image.  The inner structure of the nearly closed blossoms is well resolved. The stalks serve as „body“. There is no advantage with higher energies.

    The same composition was done immediately after the X-ray as a bracketing series on a lightbox. After returning I processed a manual HDR, the colors not to warm.

    The final fusion image is a composite of the preceding two images. Compared to the lightbox photo, the hidden stalks reappear naturally, the inner petals are outlined like a sketch.
