This is true, but for anyone just starting out with MF it's not a bad idea to stick with one
emulsion for a while so you can get used to how it responds to differing lighting situations
and contrast levels.
In general I find that Fuji's ISO ratings tend to be more liberal than Kodak's. If I consider
Kodak E100GX to be a true ISO 100 film I would then have to rate Provia 100F as ISO 80.
This difference is significant if you push the film. Pushed two stops Provia100F is around
ISO 320, not 400.
I'm going to be getting a roll of the new Provia 400X to test, and I'm hoping to get an idea
beforehand as to whether this film is rated similarly to Provia 400F, which I think should
be called 320F.
