Starting today, Martin Schoeller will be the first in a series of guest photographers to take over The New Yorker’s Instagram account. Follow @newyorkermag for updates from Twinsburg, Ohio, where Schoeller will be documenting the Twins Days Festival, the world’s largest gathering of twins. In addition to his work for the magazine, Schoeller has been photographing sets of identical twins, triplets, and quadruplets around the country since 2011, and this week he’s in Twinsburg to take the final portraits for his book “Identical: Portraits of Twins & Multiples,” which goes to press later this month. All this week, he’ll be showing us what he’s seeing on Instagram. Stay tuned!
