The first exercise is to show gradations of tone using repeated marks.  With a piece of charcoal and working at eye level we had to produce lines of varying tone on three pieces of A4 paper.  I started with the palest then got darker on the second and third.  More control was needed to create the palest marks.  The second one was quicker but less consistent and the darkest one was a lot easier and more consistent in length and width.

I think there’s a clear difference in tone between the three drawings, but decided to do a fourth one, even darker. I naturally wanted to fill the white space with this one as it flowed and felt quite rhythmic.  The four pieces show a real difference in the tone one can create from a single medium.
