A painting so detailed that one pixel is smaller than a blood cell

In short: Art history often debates which masterpiece holds the title for unparalleled detail. While the Ghent Altarpiece is celebrated for its precision, modern technology has allowed us to see deeper into Rembrandt's work than ever before—revealing individual particles of pigment and microscopic brushstrokes.

The Ghent Altarpiece, completed in 1432 by Jan and Hubert van Eyck, remains a cornerstone of high-detail artistry. Located in the Cathedral of Saint Bavo in Ghent, the massive work measures 375 cm × 520 cm. Van Eyck is renowned for using light, symbolism, and astonishing precision to create an immersive experience that blurs the boundary between the physical chapel and the painted narrative. His technique allows viewers to observe intricate reflections and hidden stories involving the famous Mystic Lamb.

However, a new technological benchmark has been set by the Rijksmuseum's documentation of Rembrandt van Rijn’s 'The Night Watch' (1642). Through 'Operation Night Watch,' researchers produced what is considered the largest and most detailed photograph ever taken of a work of art. This digital feat allows for an unprecedented level of scrutiny, where viewers can zoom in to see individual brushstrokes and even specific particles of pigment.

The technical achievement behind this image is staggering. The team utilized a 100-megapixel Hasselblad H6D 400 MS camera to capture 8,439 individual photos, each measuring only 5.5 cm x 4.1 cm. These were then stitched together using artificial intelligence to create a 717-gigapixel image—totaling 717,000,000,000 pixels. At this scale, the distance between two pixels is just 5 micrometres (0.005 millimetres), making a single pixel smaller than a human red blood cell. The resulting file size reached 5.6 terabytes, providing a microscopic window into Rembrandt's 17th-century mastery.

This comparison highlights two different types of 'detail.' Van Eyck’s detail is an artistic achievement of the Renaissance—the ability to render the world with such fidelity that it feels real. The Rijksmuseum’s project is a feat of modern engineering, using AI and high-resolution optics to reveal the physical reality of the paint itself.
