This is the contour drawing done with a #B pencil
Using the same #B, I rendered the light side in one continuous tone being sure to save the high light a little bigger than I saw it. Then I used #2B to indicate the shadow side in one continuous tone, several steps darker than the light side.
This is the finished drawing. Notice that I did not lighten the shadow side to indicate the reflected light, rather I only darkened the core shadow which makes the reflected light appear lighter than originally done.
This is what the camera saw.
