The winner of Nikon’s Small World competition shows the microscopic, magic world of printers
A look inside an inkjet, a pen, pencil and, of course, plenty of cells.
Justin Theodore Benttinen, Ole Bielfeldt, Kaelin Wulf & Ms. Rachel Flannery, Dr. Marcel Clemens, Dr. Bruno Cisterna & Dr. Eric Vitriol | Nikon Small WorldNikon has announced the winners of its Small World Photomicrography Competition for 2026, where contestants are tasked with sharing images taken through a microscope. The winner is a stunning image that shows what happens inside a printer as it puts ink to paper, with the result looking like something out of a blockbuster sci-fi movie.
This is the 52nd year that the competition has been held, and there were over 1803 entries from participants in 69 countries. We’re showing the top 20 images here, but you can see honorable mentions and images of distinction over on the Small World website.
First place – Microscopic view of an inkjet printer depositing ink onto paper, Ole Bielfeldt

Technique: Slow-Motion, Image Stacking
Magnification: 20x (Objective Lens Magnification)
Caption: Captured using a self-constructed imaging rig, using a microscope objective, Bielfeldt’s image sheds light on the previously unseen intricacies of a common process: printing words onto paper.
Bielfeldt is the creator behind macrofying, his photography and videography brand, where he combines photography, microscopy, and self-built equipment to showcase everyday objects in an unfamiliar manner. The winning image was guided by his search to answer a simple question: How does a printer place ink onto paper so precisely? At normal scale, the process happens too quickly and too routinely to notice. But under Bielfeldt’s lens, tiny droplets travel through the air before landing on glossy paper, exposing the machinery, motion, and small imperfections hidden within a device many people use every day.
“I think it was super interesting because I didn’t know how it really worked,” Bielfeldt said of the printer’s internal process. “It’s like it was magic, and I didn’t understand it, but now I do.”
Capturing that moment required Bielfeldt to rethink both the printer and the imaging setup. His first attempts failed because the printhead moved too quickly to keep a small area in focus, and the droplets were too fast for his camera’s shutter speed. Rather than turning to expensive equipment, he reverse-engineered the printer so the paper instead moved beneath a stationary printhead. Working in a dark room, he then used a flash to freeze the droplets in midair, allowing the brief burst of light to serve as the effective shutter.
“After trying and failing many times to capture the droplets in motion, I thought I would need some expensive equipment,” Bielfeldt said. “But it turned out I already had everything I needed.”
