Grapes as an object of X-raying have been inspiring me for a long time. Their structure remind the doctor of the azini of a gland or lung. The phycisist likes very much the partial and complete overlays alternating with free positions. As an artist I get an unbelievable freedom of image design.
My first X-ray imaging attempts with grapes were carried aout in October 2017. I’d forgotten !
Can something succesful be repeated ? Can it be deepened ? What is the power of the composition ?
Two days ago I tried toput my creativity into the composition. Two pictures were taken from grapes which differ only slightly. Their X-ray view on our monitor had a clearly different effect.
My colleague by chance showed up with a bouquet of small sunflowers with long stalks. Amazing opportunity !
How to show the sun in the middle of a sunflower ? For astronomers it is quite common to look at the sun in hydrogen alpha light, which is a pure red at 635nm. With artistic eyes, a red center might be overdone.
So I tried two different representations, one in BW that is close to the natural look and feel of a sunflower and one with a light blue in the center as complementary color to the yellow petals.
The surface structure of our sun can be seen like astronomers see it.
There is no photo of the next digital X-ray image of a sunflower with its stalk and a leaf:
In a digital world we can combine different digital sources. This photo of a sunflower is a composit of its X-ray, its photo on a lightbox and monchromatic sunlight at a wavelength of 635nm (Hα light).
In fact: this is an example of an impossible thing. But you may be able to feel the warmth of a sunbeam emerging of the core of the sunflower. And the petals act as prominences.
