The top 20 winning images in Nikon's annual Small World photomicrography contest.
Now in its 35th year, the Nikon Small World competition recognizes the art of photomicrography, with specimens spanning biological, industrial, and geological sciences.
Judges assess images for both scientific and artistic qualities, with the leading images displaying strengths in both areas. The images' impact, technical proficiency, originality, and informational contribution to the scientific community are all criteria used to evaluate the entries.
This 20th place winner is a 40x image of a rusted old coin. It was captured by Havi Sarfaty of the Tallinn Israel Veterinary Association in Ramat-Gan, Israel.
