Sketch of Peter,
a detail of Cima da Conegliano's The Incredulity of Saint Thomas,
Derwent Onyx Dark (just less than A4)
We were given a white pencil, a sheet of toned pastel paper and a sheet of white (I used my sketchbook for the exercises on white).
I must try to write in a straight line!
Two minutes dominant-hand, 90 minutes non-dominant hand
and the longer drawing.
After Katy's art historical explanation, Marc told us to pick one of the many faces and, starting with the nose, draw the head in 2 minutes. We then had to use our non-dominant hand and draw the same head in 90 seconds. He then told us to use the toned paper to draw a different head in one minute then turn it over and pick either of our chosen heads to work up a longer drawing. He wouldn't let us use the white pencil until towards the end when we were told to then focus on the highlights. Another excellent session.
Not shown are the images on the back of the toned paper but it's too dark now to photograph them. I owe you a photograph!
