I'm happy to hear you have a stash of the APX-25. Northstar5150, this is a "no-longer-produced" film which people have private stashes of the old stuff. It is always a pleasure to shoot, develop and print the very slowest fine-grain film, when you want to see what black and white photography can deliver.
