Most Amish today will not pose for a photograph. Considering it a violation of the Second Commandment, which prohibits the making of "graven images," the Amish believe any physical representation of themselves (whether a photograph, a painting, or film) promotes individualism and vanity, taking away from the values of community and humility by which they govern their lives. Occasionally, Amish people did have their photos taken, as you can see with the couple in the first image who likely went to a studio for their portrait in 1875. But by the time photography became popular in America in the mid-19th century and photographers and researchers armed with cameras began appearing in Amish communities, most Amish objected to appearing in or posing for photographs entirely.
