When you rate the film at a different ISO like I am talking about, you tell the processor to continue to process at the listed ISO. In NPHs example, the widely accepted opinion is that it is not really an ISO400 film. It requires 1/3-2/3 stops of EXTRA exposure to really get good enough density to make a great print.

Out of all of this, I have learned something interesting about film and digital photography. You are always (almost) better off over exposing film, and under exposing digital if you have to err on one side or the other.

I am shooting a wedding this Saturday and have decided on NPH as my

all purpose film (based on this board's overwhelming

recommendation). Are there any comments on rating this film at 320

or 250 for best results? Is this truly an ISO400 film? or more of

an ISO320?

Thanks so much in advance for your help!
