I wondered what medium format shooters prefer as a fast 800asa film? Also, I plan to shoot in a church soon (not a wedding) and am considering which 800asa film to use. I'm thinking about Kodak Portra 800 or Fuji NPZ 800. I expect substantial "golden" tones in the light given the late afternoon sunlight likely to enter through the windows as well as the non-fluro interior lighting. The interior is substantially clad in white marble. Si I expect to use a "blue" filter occasionally to keep the undesired golden tones lower for some shots. AND, I will shoot some B&W thinking I will need 1600asa to keep people shots sharp. So am looking to find the finest 1600 grain possible - Fuji Neopan? I hope to be able to enlarge some of the images (6x6, 6x9 and 6x12) up to A1 or even A0 prints. All suggestions welcome. Thanks.
