3 of 4 Portrait painting demonstration, 1st glaze glazing over grisaille - with voiceover

3 of 4 in this real time painting demonstration, painting the first glaze over a grisaille underpainting for a portrait commission. Here I begin to model the forms already drawn in the grisaille underpainting, using velaturas and glazes, mixing the colours on the portrait itself as well as on the palette. A velatura is a semi - opaque glaze of paint, ie. for me a glaze with a little white added. There is quite a bit of oil paint on the grisaille underpainting now, and I can move this around and blend it to build up the forms with a both hogs hair and sable brushes. At this stage I have been painting the portrait for around 40 minutes and half way through the first glaze.
