I never took snow images with my mamiya 7. I was wondering how should i meter a general snow scene because of mamiya's 7 spot meter. Shall I meter for the snow and then open up two stops or shall I meter for a darker object in a scene, for example a building or a tree and still open up one stop. I always use the ae mode and then use the exposure compensation if necessary. I will be shooting with the new portra 400 film. Any suggestions will be appreciated. In the mean time I will start bracketing my shots but the snow is melting at a rapid pace so I do not have the time to wait for development if I want correct exposures right away.
