When shooting I use a spot meter or when indicated an incident light meter. I understood the question to be what the personal exposure index for a particular film with his equipment and processing procedures should be. That would be dependent on the equipment not the subject. Is the shutter speed as indicated on the camera and what is the film fog? The exercise I suggested will accommodate for that. Metering a scene is a different subject.
