        John, 
                The short answer to what you are wondering about goes like 
this:
The HIGHLIGHT control adds two stops exposure to the spot metered reading.
The SHADOW control decreases exposure by 2 2/3 stops from the spot metered 
reading.
        Basically, you must spot meter a white area first then press the Hi 
LIGHT button to get white. You can't meter your black chair and then press Hi 
LIGHT and expect to get a correct exposure. 
        You're thinking that HiLight and Shadow are some complicated exposure 
metering system in its own right. It is not. It is just a convenient way to 
add exposure compensation _to your already taken spot meter reading_.
        Hope this helps, 
        George S.
