20 Spectacular Photomicrography Winners At The 2025 Nikon Small World Contest
Widely regarded as the leading contest for recognising the art, skill, and excellence in photomicrography, the Nikon Small World competition is now in its 51st year. This year, the 2025 Nikon Small World Photomicrography Competition received 1,925 photo entries from 77 countries, with 20 winners selected for their outstanding submissions. Each image highlights the beauty and complexity of subjects seen through a light microscope, revealing aspects of the world invisible to the naked eye. Through their unique perspectives, these photographers offer everyone a chance to witness the breathtaking wonders of the microscopic world.
China’s Zhang You claimed the prestigious first place with his striking image of a rice weevil perched on a grain of rice. The photo captures the insect with its wings fully extended, frozen in a moment that showcases the form and behaviour of this common but often overlooked agricultural pest. “Zhang You’s work demonstrates the remarkable power of microscopy to reveal new perspectives on the world around us,” said Eric Flem, Senior Manager, Communications and CRM at Nikon Instruments. “What makes this year even more extraordinary is that it was his very first time entering the competition, and he not only captured first place, but also placed another image in the top 20. His achievement highlights the spirit of Nikon Small World: inspiring wonder, making scientific understanding accessible to all, and celebrating the artistry of the microscopic realm.
