I did a "quick" head for both grey-scale charts. I wonder if my shadow and light family could/should be closer in value to each other, especially on the female head? In hindsight the darkest dark of the female head chart also feels like it might have been too dark in value.

AMAZING demonstration! Also Morgan, if you ever need a different occupation, you’d make a good stand-up comedian. I enjoy when you get tickled by something you’ve said. Okay …. Back to business.

I did a small study using your painting as a reference. When I first put down average-shadow-gray, it looked too dark, so I mixed more white to lighten up. Then when I started to put down light family colors, the light colors looked very dark. I should not have changed the average shadow value.

Since my canvas boards were still drying from gesso I decided to attempt this with pastel on grey Canson M-T. I put a value scale on top; I think I got a bit confused between half tone and reflected light which may have been because they were both so close to the value of the paper. Good exercise.
