Derek gave a most interesting demonstration. For his subject he chose a young golden eagle. He worked directly from a photograph which was taped to his easel. In order to complete the demonstration within a couple of hours he chose a black background and used a black pastel paper from Windsor and Newton.
Derek used a combination of soft and hard pastels and pastel pencils; many in the natural earth colours. He used a lot of blending using mostly his fingers but also a stump and a blender. He also employed a tapping technique which most of the audience had not seen before. He was prepared to break a pastel when he needed a really sharp edge.
Some photos of his demonstration are shown below.
The initial drawing was done with a white pastel pencil.
