Nikon Small World 2025 Photomicrography Winners
Nikon has announced the winners of its 2025 Small World photomicrography competition, gathering images from all around the world that show off the microscopic universe around us in shocking detail. The winning images depict a wide range of subjects, including cells from a variety of organs (and even species), insects, fungi and minerals, just to name a few.
There’s also a Small World videography competition, for which Nikon announced the winners last month.
There are twenty winners, which you’ll see in this slideshow, but there are several other honorable mentions and images of distinction, which Nikon has hosted on its site. The company says it received “thousands of entries from scientists and artists across the globe.”
1st place: Zhang You
![]() |
Subject: Rice weevil (Sitophilus oryzae) on a grain of rice
Technique: Image Stacking
Objective Lens Magnification: 5X
Location: Kunming, Yunnan, China
About the image: You is a member of the Entomological Society of China and the Entomological Society of Yunnan Province. He told Nikon: “It pays to dive deep into entomology: understanding insects’ behaviors and mastering lighting.” “A standout work blends artistry with scientific rigor, capturing the very essence, energy, and spirit of these creatures.”
The image was created over the course of two weeks out of 100 exposures taken with a medium format camera.
You told Nikon: “I had observed rice weevils in grains before, but never one with its wings spread.” “This one was naturally preserved on a windowsill, perhaps in a final attempt to escape. Its tiny size makes manually preparing spread-wing specimens extremely difficult, so encountering it was both serendipitous and inspiring.”
