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?
