I wanted to show how much depth can be achieved by using a grisaille underpainting. The pronunciation of gisaille is grizz-eye, and basically means an underpainting in a single tone, any colour can be used however, more likely it is shades of grey or brown. All the values are worked out before hand so the artist can concentrate on layering coloured glazes for richness and depth. I really enjoyed doing this piece (the pattern for the bird was from Sherry C Nelson's book "Painting Songbirds", which is a beautiful and inspiring book. This painting was done entirely in acrylics, however the same results can be acheived with oils but you would need to allow the painting to dry between layers.
