I was looking at the Kodak website. I just wanted to see if I was understanding everything correctly. From what I understand incident light meter readings are based on a 13% grey instead of the 18% that a reflective light meter is calibrated to.

Ok, so if I take a reading with an incident meter pointed at the camera by the subject's face I should have an f-stop about half a stop down from the reading off of the card? For instance if I had 4.0 on the card from the spot meter would the incident (with hemisphere) give me an f-stop halfway between 2.8 and 4.0? Then if I took a reading of the subject's face, say an average irish man without a tan I should get a reading about 5.6 or between 5.6 and 8?

If I have a wide shot of a scene that uses a lot of different lights in the scene how do I use the grey card with a spot meter? I have the main subject in a chair reading with a lamp in a dark room with splashes of light in corners and some coming in through the window at dusk. Should I place the card near the subject under the lamp? How do I make sure I represent proper skin tones? Should I get proper skin tones once I figure out my f-stop for the grey card? Can I then use the spot meter to look at the scene and find out how many stops parts of the room are over or under from the neutral grey?
