I have an album of old family photographs that date from between 1895 and 1910. I'm trying to date them and identify as many as possible of the people in them. One of them is a family group centred around my great-grandmother, and one of the people in it (possibly my grandfather) is carrying a folding camera. I wondered whether people here with more experience than me can say anything that would help to date it within the window above. Is it a half-plate camera? Can you say anything about the model? Going by my great-grandmother's age compared to other photos of her, I think it's probably 1900-1905. Many thanks!
