Value studies of Mr. Plasterhead, (the one with hair.)
we toned our drawing paper with hard pastel by grinding it to dust with a sanding block, then burnsihing it in with a paper towel. This became our eraser. then we blocked out our head, and used a kneaded eraser to locate everything lighter than the tone. The goal was 5 values, and to eliminate all lines from our final drawing, describing everything with shape and light-next-to-dark.
the second one had strange underlighting, and I did it much more quickly than the first. Yes, its the same plaster head, in spite of looking like a totally different person! Also, teacher noted it has a strange skew, due to my bifocals sliding off my nose and poor easel placement!
yup, it's humbling how challenging this is!
