Istanbul, or Constantinople as it was called in 1850, dazzled visitors with its modernity—its bustling harbor, new industries, and emphasis on social progress—against the backdrop of ancient mosques. The city’s Ottoman sultans were dedicated to advancing its industries and reputation. In the 1850s, European photographers were recruited to establish studios in the city, but soon native entrepreneurs provided competition. Many studios offered panoramas, depicting Holy Hagia Sophia Grand Mosque above the busy harbor. Though this print remains unattributed, it stands as a wonderful example of the coproduction of photography and modern life in the mid-19th century.
