    Nautilus shell X-ray fusion photo of energy levels

    3. März 2019 / No Comments

    Different energies of X-ray radiation mean different transparency of an object. There is an example in my FAQ using a Nautilus shell.

    Instead of compressing images of different energies to a single image today I subtracted the 70 kV image of a Nautilus shell from the 40 kV image.

    The central parts of the Nautilus shell are more dense and show a significant higher difference. The core of the shell gets shiny. This is how it looks like:

    In positive X-ray representation you can compare the results. Left hand is the compressed image of 4 different energy levels, right hand the difference image.

    Dahlias fusion X-ray HDR photo

    2. März 2019 / No Comments

    Long time ago my friend Harold and I did these X-rays in my practice. There was so much to do. Today was a chance to process the fusion images. Some details can be found in my FAQs.

    The manual HDR is already appealing to our eyes.

    There is some charm in the X-ray image of the same composition. The hidden parts of the stalks can be clearly seen.

    The fusion image of this composition shows both color and hidden structures.
