FWIW You know, when I was a lot younger, like 40 years ago, the ASA numbers were bumped up. I think TX went from 200 to 400, PX went from something up to 125, I think. And all the photographers went into an ecstacy because ASA was now closer to "true".(posted 8167 days ago)I never could see that, but then there are a lot of things I have not seen through the years
