well, sorry for my joke, cause u put she then later he.
To answer ur question, a good way should be using indecent meter. If spot meter, take reading of the shadow, then highlight then use somewhere in between , for spot meter, you can try to take reading like more than 2 , for like 4 spot in the frame w different light , then take the average. Best is include one reading on model face , the average put near to the model face reading side i think.
