Who wrote the notes of the early photographers and when?

During the period of 1854, Rosen, an early photographer in China and assistant of American photographer I Brown, interviewed Japan for half a year with the fleet led by Madden Berry, commander of the American East India Fleet.

1August 7, 854, Rosen returned to Hong Kong. In the form of a diary, he published his interview with the American fleet in the Hong Kong Chinese monthly "Far and Near".

Rosen wrote in his diary that he stayed in Shimoda for a month and visited and filmed in Da 'anji several times. At that time, Japanese technology was still very backward, even worse than China. People know almost nothing about photography. Rosen also wrote that one of the gifts given to Japan by the United States was a camera. When local officials and people saw it, "many people were surprised." These written records are rare notes of early photographers.
