'Thou shalt not make unto thee any graven image' — Second Commandment. Amish interpret literally: image of person = idol. Photograph = sin.
Rules
Don't photograph others (forbidden). Don't be photographed yourself (forbidden). Don't keep photos (forbidden). Don't own a camera (forbidden). Mirror — okay (reflection isn't permanent image). Landscape drawing — okay (no people).
Reality
Driver's licenses (for English employees): ID photo — problem. Passport (for Canada/Mexico trips): photo required — religious exemption? Depends on state. Security cameras at furniture warehouses: technically not their camera — gray zone.
