I would just like to be certain I'm thinking this through clearly. Let's say I'm shooting portraits. Just a regular portraits, nothing fancy. Assume it's lighted simply and the camera is set to SPOT metering. Also assume, my subject is a white skinned person. If I meter on this person's face, the SPOT metering of the camera will place this person's face on ZONE 5. Because of the subject's tone, I wouldn't want this person's face to be in zone 5. I'd want the face to be in ZONE 4. I'd set camera's exposure compensation to be in +1. Now, USING THIS SETUP, I meter this person's face, LOCK THE EXPOSURE, recompose, and shoot. I'm not interested in knowing better ways of doing this, so please don't suggest. I am; however, interested in knowing if I am applying the correct logic, and using the zone system, metering system, and exposure compensation setting correctly. Thanks in advance.
