I often visit the Nikon Ambassadors listing on the Nikon USA’s website to see if any changes have taken place, either additions or removals. On my recent visit, I noticed one name missing, that of Joel Sartore, of the Photo Ark fame. According to Joel Sartore’s website, he was invited and accepted Nikon ambassador membership in April of 2016 along with Matthew Jordan Smith, Deanne Fitzmaurice and Joey Terrill.
