George Barker was a British photographer born in 1844. He is best known for his photographs of the Isle of Wight, taken in the late 1800s. Barker was a member of the Royal Photographic Society and exhibited his work at their annual exhibitions. Barker's photographs of the Isle of Wight are notable for their composition and use of light. He often captured the island's rugged coastline and picturesque villages, showcasing the natural beauty of the area. His images were widely reproduced in books and magazines of the time and helped to popularise the Isle of Wight as a tourist destination. As well as landscape photography, Barker also took portraits of prominent people of his day, including members of the Royal Family. He died in 1894 at the age of 50, but his legacy as a pioneering photographer lives on.
