There are two schools which has developed its own metering technique.
- Zone System.
- Beyond The Zone System.
Zone System: Basically rely on spot-metering(reflected meter) the important shadows and placing it on appropriate zones. Mostly on Zone III or Zone IV. This technique works well for the negatives but you may need to test your film.
Beyond The Zone System(BTZS): Though it has some arguments favouring reflected meter, it emphasis mainly on Incident meter. This technique works remarkable well but you need to test the film and have the curves ready. I may recommend you to read the book with the same title.
In the mean-while I got some amazing negs from Italy shooting in Venice, Rome, Pisa and Florence will post them soon.
