That's really high quality for literal potato photography.
(Context: The autochrome used starch particles from potatoes - some dyed red, others green, others blue - over the photosensitive layer on a glass photography plate as a color mask that was used both for filtering incoming light as the photo was taken, and for producing appropriate colors when viewing. The images needed to be shown backlit at high intensity, and neither color reproduction nor sharpness was very good. Starch was cheaper than three times as much photosensitive material, though.)
