Well, you choose the film to match the lighting you'll be using, there's non of that choosing w/b stuff AFTER loading the film.
To be fair there's only really daylight temp or tungsten temp film, a tungsten balanced film will be marked with a "T", its for use under tungsten lights obviously, like ordinary 60w filament lamps.
You can't b****r about with iso either, the iso is what the film is, when you dial iso into that camera you're just telling it what iso the film is that you just put in so the meter can calculate the best exposure.
So if its iso 200 film, dial in iso 200, you can't change it, if you want to use a higher iso you need to load higher iso film.
I don't know what the colour problems might be with those particular images, but it might not be the film temperature, sometimes the processing can be a bit dodgy, sometimes it might be the film if its cheapy, or it could be daylight film with tungsten light leaking in from somewhere..:shrug:
