Hans Neleman discovered New Canaan by mistake. It was late-1993 and the Holland native had lived and worked for 10 years in Manhattan after earning a bachelor’s degree in film and photography from The Polytechnic of Central London and a master’s degree in studio art from New York University. A still-life and freelance commercial photographer with his own studio in New York City, Neleman had set out that day with a real estate agent to find a house in Westchester County. They got lost and found themselves in downtown New Canaan. “In the ‘90s you didn’t browse online and find anything,” Neleman recalled on a recent afternoon.
