After drawing in this Bouguereau I painted the grisaille. I’m not normally used to modelling the forms so thoroughly but I found that to be a very valuable experience, because I don’t think I have ever done it! I have found in the past that as long as the drawing is correct in the grisaille then the glazes and half-pastes (with white) will continue to refine the modelling.
I was also conscious of not painting the grisaille too dark to begin with as the later glazes will darken it further. Also it is difficult to tell wether it is purely a glaze that creates the shadow tone here or if there are thinner glazes over the grisaille. I can’t actually tell if the shadow area on her neck below her chin is a thicker rich glaze or the result of the shadow painted in grisaille, showing through the glaze. It doesn’t actually look like there is any grisaille showing through. I recognise the glaze as a mixture of green and red (which ones I’m not so sure). My hunch though is that it is created from Sap Green and Cadmium Red or Vermillion. I left it as a compromise with a little shading in the underpainting. The sharper transitions can all be softened with glazes and I will show this in my next video.
The whole point of the grisaille is that you don’t lose touch with the drawing and it is visible through the glazes. Its a chicken and egg scenario trying to work out which came first. Only time will tell, and when I do the glazing I should have a much clearer idea of how Bouguereau did it.
In the grisaille I have deliberately left some of the transitions between light and shade a little sharp, and some of the lighter areas quite flat. This I hoped would enable me to concentrate on modelling the forms with the colour glazes which is what I think Bouguereau did.
All the modelling around her shoulders could have been created with glazes only over a fairly flat underpainting. Also I have not really darkened the area on her left cheek as I’m sure this has been created with a red glaze. I once saw a photo of one of his paintings where the glaze was flaking off but unfortunately I can’t find it again. This proved though that so much of the modelling was done with glazes alone, and that these glazes gave the work that translucent quality.
