My friend took these pics recently. I'm not sure what kind of camera she has but it's film, not digital. They all came out super grainy, but she said thought her ISO was 160. Would that ISO cause this much grain? 1. 2. Sorry if they're really big. I took them from her facebook because I don't want to put them on my Photobucket since they're not my pictures. Thanks for any answers as to what caused the grain. I don't know any of her other settings, and neither does she since she was just goofing around.
