I got some Ektachrome (expired) 100 as a gift. The guy who gave them to me told me to rate at 200 ASA. I really don't understand why to do this (but listened to him and got cool enough results). I tend to think the frames I shot leaning more towards a 120 ASA speed were a little muddier. Any thoughts on why might this have hapenned? I'm a little confused because many people sugest (online) to overexpose expired E-6 rolls a little, and I don't really know whose advice to follow in other emulsions further cases, I'm getting some Provia in a few days.
