Composite of a sunflower: X-ray, light and Hα

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.

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
