One of the most important things that has happened to me in all the years I have been portrait painting was going on a course run by Louis Smith in 2014, learning about glazing. Looking at his website I thought this would be about glazing as I understood it where you have a very thin translucent layer of paint and you go over a grey underpainting, or dead layer, like Caravaggio or Ingres. We learned to glaze over an underpainting, but the glazes felt more like ‘half-pastes’ as they were not entirely transparent. Even so it transformed the way I approached colour mixing for portrait paintings, and I learned amazing colour combinations of reds and greens which are now the foundation of my approach to painting a face. I’ll write about them in another blog post. I found out about Louis Smith from Jonathan Jones, the Guardian newspaper art critic.

On the course, which was over a weekend, we used a monochrome print from another portrait and went step by step through the process of building up areas of colour, slowly refining and blending each.
