A Printer Printing a Picture of Paper, Onto Paper. I Can't Look Away...
A photograph of an inkjet printhead firing droplets, taken through a microscope, just won Nikon Small World, the big prize for photography through the microscope: Ole Bielfeldt, a 25-year-old German experimental photographer, beat 1,802 entries from 69 countries with his microscopic view of an inkjet printer depositing ink on paper.
The video version, a printhead raining droplets in extreme macro, posted to Macrofifying on X under the caption "A printer printing onto paper," is the loop I keep rewatching. Getting it was engineering, not luck. The droplets move faster than a camera's shutter, so Bielfeldt deconstructed the machine until the sheet moved under a stationary printhead, worked in a dark room, and let a flash serve as the shutter, freezing the drops mid-air.
