Ok, The older Bristish plate cameras used 15x12 inch film (plates).
The old European plate cameras used 30x40cm.
40cm = 15.748 inch
15 inch = 38.1 cm
So, are these really two different size cameras?
The little bit that I have seen about the modern availability of film in this size is called 30x40cm.
So, if someone were going to have modern holders made to use in these cameras, which size should they take or are they actually the same...?
thanks for the help.
