Hi,
I want to figure out what is the minimum image circle required to shoot an interior room with the following field of view marked in blue lines. I need to capture all the openings with some wall space on either side.
148086
Ideally I would like the space to be compressed as much as possible and would prefer to shoot 210mm or 150mm focal lengths.
I’ve made the following diagrams to figure out how many exposures I would need to join to create the
required image.

1. Are these drawings correct? In other words is it correct to say:
If I want the shot at 210mm I need 4 sheets of film and a lens with a image circle of 384mm or greater
If I want the shot at 150mm I need 3 sheets of film and a lens with a image circle of 275mm or greater
If I want the shot at 90mm I need 2 sheets of film and a lens with a image circle of 165mm or greater
2. If I were to make all three shots would it be correct to say that the 210mm composite image would look more compressed, the background beyond the windows would appear closer than the other two configurations?
I'm new to the large format world and trying to get my head around it, any responses would be greatly appreciated.
