Hello Everyone-

I am making a 4x5 B&W image that will be scanned in & printed out very large.
Appx 14 x 16 feet. (Either on vinyl or canvas, most likely vinyl) I would like to have as little grain as possible, as people will be able to view the image very close.

Does anyone have any suggestions as to what film/developer will give me the least grain or for working this size?

Thanks so much,
Sue
