For nearly four decades Nikon has been organizing its Small World microscope photography contest and this years’ entries are surely one of the best ever. 20 winning photographs were selected from nearly 2000 submissions for their originality, informational content and visual impact. The first place went to Jennifer Peters and Michael Taylor for showing the blood-brain barrier in a living zebrafish embryo, which Nikon believes is the first image ever to show the formation of this barrier in a live animal.
According to their website, “Small World is regarded as the leading forum for showcasing the beauty and complexity of life as seen through the light microscope.” The competition is open to anyone who’s interested in microscopy and photography. There is also a video competition, called Small World In Motion.
Take a look at the top 20 photomicrographs from the 38th Nikon Small World competition.
