Expired Fuji NPS 160 shot at 400 (whoops!) - to push or not to push?

[raywoc]

I am over halfway done shooting a roll of expired Fuji NPS 160 film, and for some reason thought it was a 400 iso speed film. So of course my light meter was sent to 400 ISO and all my shots are going to be 1 and 1/3 stops under-exposed. When the roll is finished and developed, I plan on scanning them in myself. So my question is this - should I tell my lab to push process the film when it's developing to take up the extra stop, or do you think it would be better to develop at 160 ISO and compensate the 1 1/3 stops when I scan?

Years ago I did the thing w/ an old screw mount Leica using your film. It was only after I got the negs back that I remembered that my meter had been set to 400. They looked just fine w/ normal processing (Walgreens).

I have a lot of expired NPS and mine has lost considerable speed -- I'd say it shoots at around ISO 80. Based on this experience, I would definitely push process.

In my experience, NPS did not do well with any underexposure, so I would push a stop.

I agree with newcan1. Push one stop.

If the shots you did are important to you an don't want to lose it there is something you can do. If you have another roll of the same film, shoot it the same way you shot this one then process it normal and see what happens.
