See the Girl with a Pearl Earring painting in 10-gigapixel detail – Engadget

The microscope was programmed to automatically focus on the painting and capture the images, then stitch everything together. Certain regions of the painting were captured in even higher detail using the 3D capabilities of the microscope. For those, each pixel was equivalent to 1.1 microns, with multiple images of each region captured to create a topography map, allowing experts to see the differences in paint height and other details.

“The Hirox software is automatically moving the lens up and down with very high precision, capturing a series of images at different focus [points] and combining them in one fully-focused image,” said Leonhardt. “The motorized X/Y stage is then moving to the next position, creating a high-resolution panorama.”

In one area of the left eye, you can zoom in to see the pupil and then zoom in much further to see the light source reflected in that pupil as a couple of blobs of paint. Another section shows two small dots of paint Vermeer added to give texture to the garment.

By switching to 3D mode, that same blob of paint on the pupil can be seen from edge-on, revealing topographic detail in the paint and cracks. You can also explore other regions including the subject’s mouth, garment and, yes, those famous earrings. This kind of detail is incredibly valuable for curators, as they can track wear on the painting and explore past restorations. Hirox has created a special site for the scan, and you can zoom in and check it out in 3D right here.
