New guy has a question...I have a Nikon 8008. I want to shoot a B&W portrait using natural light only (by the window) . Can I just set on auto and use 100 film? What will be the results? Suggestions? Some time back I shot something very similiar using an old Pentax 1000. Turned out fairly well (IMHO); however, the settings I used came from a magazine and I have no idea what they were in order to replicate what I did then. Help!
