Would like to see some "real life" shots with this film, rather then test charts, which are even more difficult to interpret when you can't actually see them.
I've used a few rolls of this film, just out of curiosity, not for any serious work, and find it quite OK and comparable with other consumer films. A setting of 200ISO seemed fine, and, as with some other C41 films, a touch of overexposure seemed to do no harm. From your posting, are you suggesting that the effective speed of the film is much higher than than 200ISO?
(I've read that Lucky were associated with Kodak during their venture into China, and presumably gained knowledge and technology from Kodak during that time?)
