I'm new to large format and am considering buying an LF field-camera, but I don' t know how much rise I will need. I rarely photograph architecture, but will ne ed to correct perspective now and then. I'll be using a 90mm f/4.5 or 5.6 lens for the vast majority of my photographs.
I only have a 150mm lens available right now, so it's hard for me to know just w hat I would need. I would appreciate any help with this.
