It may look like an alien perched on a crystal, but the winning photo is by Zhang You from Nikon’s small world Competition is not as evil as it seems. In fact, an insect lover snapped a stunning photo of a rice weevil sitting on a grain of rice. It’s stunning images like these that make Nikon Small World so unique in the world of photography competitions.
Launched in 1974, the competition highlights the world of scientific microscopy and digital photography. By introducing these images to a wider audience, they help the public understand how artistic microscopic photography can be. For example, Zhang spent years perfecting his craft by examining insect behavior, and his winning photo shows the benefits he gained from this practice.
“It is useful to delve into entomology: understanding insect behaviour, mastering lighting,” he says. “The outstanding work blends artistry with scientific rigor, capturing the essence, energy and spirit of these creatures.”
Interestingly, this was Zhang’s first time entering the competition, and not only did he win, but he also secured another spot in the top 20 list.
“His achievement highlights the Nikon Small World ethos: inspiring wonder, making scientific understanding accessible to all, and celebrating the ingenuity of the microscopic field,” said Eric Flem, senior director of communications and CRM at Nikon Instruments.
Other key images include everything from pollen grains trapped in a spider’s web to the muscles of heart cells, demonstrating the diversity of what can be imaged under a microscope.
The announcement of these winners follows Nikon is a small world in motion A competition that awards excellence in moving images captured with a microscope. Combined, they both offer a revealing look at the unseen world that surrounds us.
