I was just reading about the Zeiss Ikon ZI rangefinder at http://www.shutterbug.com/content/ne...igh-end-system and this statement had me wondering
"As usual, the meter is designed to give optimum exposure with transparency film, where exposures are keyed to the highlights. In black and white, or even with color negative, it is often desirable to set a lower film speed than the true ISO for contrasty subjects where you want good shadow detail. This is not a shortcoming of the ZI: all through-lens meters designed to give good transparencies suffer from the same drawback. With the ZI we followed our usual practice of setting negative film speeds at anything from 1/3 stop lower (EI 80 for ISO 100) on "cloudy bright" days to a full stop lower (EI 200 for ISO 400) in hard, directional sunlight with inky shadows."
With this in mind, I was wondering if any of you have any advice or insights as to whether the meters on the Hasselblad (I have a PME5) and Mamiya (the AE Prism Finder for the RZ67 and the meter on the 645AFD) behave in a similar manner.
1. for Mamiya 645AF/AFD users who shoot film, do you set the film speed on the back to be slower, e.g. loaded ISO400 film but setting it at ISO320?
2. for Mamiya RZ67 users with metered prism finders, do you underexpose by 1/3 to 1 stop when shooting film, or set exposure compensation to -1/3 to -1 when shooting in AE, or set the film speed on the RZ67 Pro backs to 320 instead of 400 when using ISO400 film?
3. for Hasselblad users with metered prism finders, do you underexpose manually or set exposure compensation
or do we just leave it alone?
