My mom, knowing that I am short on cash right now (University sucks), just bought me 8 rolls of Kodak MAX ISO 800 film. Though her intentions are good, I don't usually use or need that speed of film. When using this film would manually changing the ISO on my camera to 100 or 200 ISO give me the same effect as using actual 100 or 200 ISO film? If so, does it mean I still have to deal with the quality issues of ISO 800 film (ie. grain size, colour, etc.)? Thanks for the newb help!
