I'm wondering which color film is considered better (if that's possible) for use photographing Rome. I am trying to decidde between Provia 100F, 400X, Reala 100, 160NS, and 400H. I'm sort of torn which is best for city environments. 400H is my all time favorite color film so that's going to make the trip with me, but for 100 speed film, I'm not sure if I should stay with negative film or maybe shoot some chromes. Or I could stay with all 400H and buy a ND filter for my camera for those wide open shots. Final use is for personal family stuff, nothing more. Format will be 6 x 7 and maybe 6 x 4.5. Thanks for any opinions!
