I was wondering whether it's better to shoot slides indoor with tungsten balanced film or to use a more sensitive film with a color correction filter. The following issues have been posted in various forums: 64T film has finer grain than 400X. With a filter I can balance for anything (fluorescent, daylight, ...) without swapping film backs. The new 64T film has been lambasted as having an awful green-yellow cast. So what would the pros/experts/more experienced users here recommend for indoor shooting?
