Hyderabad: From the smallest creatures to the biggest ones, the microscopic view is way intriguing and different from what is seen with the naked eye. Having realised this, Jason Kirk, director of a microscope-imaging facility at Baylor College of Medicine, started to tinker with microscopes and used them to photograph several things from his backyard.
Having chosen a Southern live Oak tree, Kirk illuminated the leaf’s small-scale structures with a customised microscope. He then captured about 200 images and stacked them on top of each other to create this vibrant portrait. Have a look:
The result shows the leaf’s trichomes – little outgrowths that protect the plant – in white. Pores that help the plant regulate gas flows, called stomata, appear in purple. Vessels that carry water through the leaf pop out in blue-green, according to ‘Business Insider’.
That technical handiwork led Kirk to win first place in this year’s Nikon Small World competition – a contest launched in 1974 by the camera company – to recognise the achievements in microscope photography, also known as microscopy. The Nikon Small World competition was created to show the world how art and science come together under the microscope.
For the 2021 competition, Nikon received nearly 1,900 entries from 88 countries. A panel of judges selected 20 winners and recognised 80 other images for distinction or honourable mention. Here are some of the pictures that made it big at the competition:

Cotton fabric with pollen grains
The microscopic picture captures how the fibres weave together. The yellow circles are a few stray grains of pollen that got caught.
