Just to clear up any confusion the film Fuji calls FP100c45, is the 4x5 ISO 100 color pack film, comes in 10 exposure film packs to fit 4x5 film pack holders as made by Fuji and Polaroid. If it doesn't have the "45" digits at the end of the item number, then it is not the 4x5 size pack film. It indeed is far better color and consistency than current Polaroid stuff.
