    Purple Clematis

    Long lasting blossoms, turning up every year: my purple clematis in our garden.

    It was my third X-ray session with flowers this week. Third fusion imaging attempt. After blue cornflower and blue aquilegia now a purple clematis. Big data on my hard disk.

    Today we did it with mammography at 30 kV and 50 mAs. Lower noise ! Here is the positive representation of a single clematis:

    I processed the lightbox HighKey series with a mask. There was a shift of 2 or 3 pixels from the lightest to the darker images. So I processed everything a second time to compensate for the shift. The HDR image shows a cut stalk. Photoshop is made for this.

    The stalk can be lengthened like in the preceding X-ray. The fusion image shows hidden leaves, the core of the blossom and stalks much better:

    The flower looks pretty fragile now, close to its natural appearance.

    Red calla lilies

    With my new glasses in my pocket I gazed the nearby market place on Saturday. I was captivated by six red callas whose price I could knock down to 10€ for all of them.

    With my Zeiss 50mm Macro lens and no tripod I was trying to get nice shapes late in the evening. The following images have been processed using Lab color to enhance contrast and colors.

    Just normal light of our living room let me to a nice coloring and interesting shapes. The blossom next to the lower right corner is a Siamese twin on a double stalk.
