These rusty and dusty old cans were our subject matter last Wednesday at Dundas Valley School of Art. My demonstrations have been focused primarily on soft-edge techniques and brush-handling this term. I added a new wrinkle to the process on Wednesday evening.
I started the demo with a pencil drawing and then taped around it to create a composition. Next, I painted a very light and slightly varied wash across the whole image, using a mix of Cobalt Blue and Raw Sienna. When the wash was dry, I continued the painting and started with the bigger shapes, often touching in a new colour or value and letting it run a bit. Gradually, the image took shape as I continued to work with a ‘light to dark’ and ‘big to small’ process.
This demonstration took a while. The students watched the initial washes only before they got to work. I carried on with it as they painted. I’d do a step and hold it up to show them. After walking around the studio to give feedback, I’d do another step and so on. Once in a while, a sustained demo can be helpful but must be balanced with the student’s painting time.
The preliminary wash idea was new to most of the class but everyone tried it. In a way, it breaks the creative ice. All of the sheet is covered by paint right away even though it’s a light wash. The gritty old gas cans were the right subject, as well. It’s hard to get too precious as they’re so worn and they’re fun to draw.
