Hi there I hope this is the right forum. I understand that 'history' questions belong here, in 'philosophy'. I am not a photographer but I hope to beg the expertise of the many of you that are. I'm doing some creative writing on a story set in the 1940s in the UK. Part of the plot hinges on the idea that a photo taken in the mid 1920s (an image of the person) could pass as having been taken in 1942-1943. In terms of the technology of photography of that era - is this believable? Thanks so much in advance for your time.
