which film ?greenspun.com : LUSENET : Large format photography : One Thread
I am using an czech made sheet film "FOMA 100" and as I looked on the graphs and something was wrong. The question is that is it possible that my film is not suitable for ZS tests ?

No. No matter how different each manufacturers films response to light, it can be calibrated to the Zone System. If you are getting data that looks bad, chances are you made a mistake somewhere. Either exposure errors, development mistakes or something else. Contact the manufacturer and get their curves to use as a reference point and make sure you are performing the tests correctly.
