The tutor, Robin Mackervoy, gave a most interesting and absorbing demonstration. Robin worked from a smaller watercolour scene. He used a canvas prepared with a warm yellow wash to complement the predominantly cool colours of the final picture.
Some photos of the demonstration are shown below.
A rough background scumbled in and key positions marked
More work on the sea and sky, and the major boats indicated
Interest in the sea and sky progressed and some darker details added
Masts and sails added together with more foreground detail.
This was the end of the demonstration as far as time allowed.
Finer details of the ships rigging etc. would be added later.
