According to historical records, the earliest color photos taken in China should be the photos of founding ceremony in June 65438 +0949 1 October1when China was founded. However, in May, 2004, Kunming exhibited 250 color photos, which were appraised by experts from the National Museum of China, and were the earliest color photos found in China so far. These photos were taken in Kunming, China, on 1944 by two American soldiers who assisted China, Mr. Clinton Mi Le and Mr. Robert Burcher. Now they have been given to the National Museum of China for free. However, according to the latest information available to the author, the earliest color photo in China is not the Kunming color reversal film shot by 1944, but the color photo Spring Tour shot by Chinese photographer Jin Yu 1937. This discovery, if verified by relevant experts, will once again rewrite China's best photographic works.
