I have only one or two family photos from that era where there is someone holding a camera in the shot. These are not shoot-yourself-in-the-mirror shots so I can only guess as to what the camera was that took that photo. Perhaps though other photos in the album are from the one that was photographed? I have wished for some means to deduce the camera a photo was taken with — or at least reduce it to a range or family of cameras. In terms of aspect ratio though, as an example, a lot of that will come down to the lab the processed the prints as the negatives are no longer available to me. EDIT: Some family photos from the 1920's. In the 3rd one, dated 1924, a woman sits with a 1920's camera on her lap. https://imgur.com/a/1920s-family-photos-wygcrLH https://imgur.com/a/1920s-family-photos-wygcrLH
