Scenario
Let's say that the film has a box speed of 100 ISO and you have determined that your personal EI is ISO 50.
Setting the spot meter to the box speed (ISO 100) & pointing it at say a grey card in even light will give you an exposure reading for Zone V
Now... if you was to set the spot meter to your personal EI and point the meter at the same grey card in the same lighting, would this now give you an exposure reading for Zone V or Zone VI
