For this demonstration, I used my customary, extensive palette of 16 colours. I premixed a limited number of flesh-tones. Three for the light parts, one for the shadow, three neutral grays and a mauve colour. Because I elaborated the drawing accurately, I could make use of the tonal values of the charcoal. In the beginning I used citrus turpentine to dilute the paint. This approach enabled me to paint rather transparent to start with. In simple planes I started the painting and little by little I worked it out entirely. The whole session took seven hours over two days.
Also you see me using my home made viewer or colour checker. Make one yourself.
the best way to have a good tutor at home
Marvelous work, Ben!
What fixative did you use?
The fixative I use is shellac/white spirit. But only very thin.
Love your work Ben. I find your tutorials very rewarding. Thank you.
