Can't be a photochrom
The photochrom process took at least 10 minutes to capture the image on a bitumen layer. Therefore, it could not have been used to photograph moving scenes like cattle. Cattle will not pose stock-still for 10 minutes. What grounds are there for saying this was a photochrom?Ttocserp 02:08, 5 September 2022 (UTC)
