I shot a roll of cinestill 800 at 1600 last week and my photo lab received it today. I asked them to push it 2 stops as recommended by Cinestill's FAQs. The lab told me they can't push C41 and asked me what I want to do.. The first half of the film was shot at night / in low light, which is why I shot at 1600, so I'm apprehensive to develop as normal and get awful results. The second half is shot in a brightly lit gallery so will probably turn out ok if I develop as normal. Has anyone used this film before and pushed it then developed as normal? I know the film is actually 500iso Kodak 500T, but have no idea whether to instruct my lab to devleop as normal or if I should have the film sent back and pushed in a different lab?
