Hayfever sufferers have Swiss scientist Martin Oeggerli to thank, because his pictres of pollen may help them face the fear of an invisible enemy. Oeggerli took 10 years to perfect the technique on a 250,000-pound microscope.
He said his work, a mixture of science and art, aims to "show a hidden but unimaginably beautiful realm of our planet".
The pollen is covered in gold, fixed to a slide and put into an airless chamber to be "photographed".
As omages come out in shades of grey, Martin colours the pictures himself on a computer.
"To take 10 images of one item takes two days - it makes these pictures unique," the Daily Express quoted him as saying.
