Went to a new life class last night at RAW in Wiltshire. The evening started by looking at some sketches made by Seurat. No lines, tone only. Then we had a go.
We worked positive then negative; graphite on to white paper, followed by charcoal lifted using finger, sponge and putty rubber, gradually revealing the form of our model as we put back the light. Hard! But good to shake up a few predetermined concepts.
