8 x 10 oils
Grisaille painting isn't seen often these days. It was a classic technique favoured by the masters and students to produce a monochrome version of a painting before colour was added through glazing. It was very similar to a drawing, or a sculpture, but done in paints.
With the advent of 'alla prima' painting, grisaille has dropped from favour. Adding another step to a painting seems wasteful of time if you're creating a painting all in one sitting.
I have to admit that I haven't used grisaille for a very long time either and my prompt to try it again is this portrait. It is being done from a greyscale image, as there was no other available from the individual. So the time seemed right to work up a grisaille image then see if I wanted to move it further with colour glazing, or simply leave it as a monochrome piece.
This is about the half way mark. I've got the shapes and values it, now to deepen the values and tweak the shapes. I'm using oils here, burnt umber and titanium white and need to let the layers dry a little before refining it more.
