Most people give little thought to what happens inside an inkjet printer. Paper goes in, a mechanical whirring begins, and a finished page emerges. For German photographer Ole Bielfeldt, that familiar process presented an irresistible question: How does a machine place microscopic droplets of ink with such extraordinary precision?
He decided to take one apart and find out.
The result earned Bielfeldt first place in the 52nd annual Nikon Small World photomicrography competition, announced October 21. His winning image captures tiny droplets of ink suspended between a printer's nozzles and the paper below, transforming an ordinary household machine into a landscape of seemingly impossible detail.
Getting the photograph required considerably more than pointing a microscope at a printer.
Bielfeldt's early attempts failed because the moving printhead traveled too quickly to remain in focus, while the droplets themselves moved too fast for his camera's shutter. His solution was to modify the machine so the paper moved beneath a stationary printhead. Working in darkness, he used precisely timed flashes to freeze the ink droplets in midair.
The finished image, captured using a microscope objective with 20-times magnification, reveals a physical process that happens countless times every day but almost nobody actually sees.
Bielfeldt's fascination with microscopy began during the COVID-19 pandemic, when he discovered an old school microscope in his parents' attic. He built a makeshift adapter from wood and a tube, connected it to his father's camera and began teaching himself through experimentation.
Today, he documents his experiments through his photography brand, macrofying, showing audiences the extraordinary details concealed inside familiar objects.
But his winning photograph arrives at an especially interesting moment for the relationship between photography and artificial intelligence.
Bielfeldt has said he prefers photographing real subjects rather than using AI to generate images. His work can involve focus stacking, Photoshop and retouching, but the underlying subjects and physical processes exist in front of his equipment.
That distinction gained unexpected relevance earlier in October, when Nikon disqualified the original winner of its separate Small World in Motion video competition. Following a review, the company determined that the entry violated its generative AI rules and revised the rankings.
The controversy involved a video purporting to show microscopic movement in airway cells. Its creator disputed suggestions that AI generated the underlying experiment or cellular motion, saying the technology was used to help visualize features. Nikon emphasized that its decision concerned competition eligibility, not the entrant's scientific reputation or intent.
The two competitions are distinct, but together they illustrate a growing challenge for scientific imagery. Digital tools can enhance what a camera records, while generative systems can also produce convincing images of things that were never observed. Determining what an image represents becomes increasingly important when photography serves as both art and evidence.
Bielfeldt's achievement is compelling because the technical ingenuity is inseparable from the discovery. He didn't simply imagine what microscopic printing might look like. He dismantled a machine, solved a series of practical problems and captured something that was actually happening.
At a time when increasingly sophisticated images can be generated almost instantly, there is something refreshing about a photographer who spent so much effort answering a simple question about an everyday object.
The printer was doing what it had always done. Someone finally found a way to watch.
