Need guidance on landscape exposure settings [View all]

I inherited my father's professional Graphlex full format camera. It has not been used in 40+ years. Before I sell it, I would like to shoot a few pictures of snowcapped Mt. Hood which is spectacular this time of year.

I know I can source the 4x5 B&W film sheets. I have film holders that I can load in an improvised dark room. A local camera shop can develop the film and make prints.

I have no idea what kind of exposure setting to use. The subject will be bright with a darker foreground. With the process being kind of expensive, I would like to be in the ballpark before I waste a bunch of film.

Does anyone in the forum have guidance?
