Here is a new video of me working on a first colour glaze in oils, over an acrylic grisaille underpainting, which is a new medium for me. I’m trying to speed up the process a little bit. It took a while to get the hang of acrylic, something I’m still progressing with. The grisaille is done using raw umber and titanium white, but hopefully the video is self-explanatory.

I’ve nearly finished this portrait painting. Its had 5 glazes over the initial underpainting. This picture shows the grisaille, the first glaze (which I filmed and is on youtube) and then the 5th glaze which is almost the last one. I still intend to go over the hair and background again amongst other things. The background was a dark green the glaze before this! It still shows through and gives it a nice depth. The lovely thing about working in this way is that everything can change with just one glaze. This portrait has been through many stages while painting each glaze. Sometimes I misjudged a colour or hue or the values of light and dark weren’t right. In each case I was able to correct the painting in the following glaze, either lightening or darkening.
I love painting highlights in a portrait so I guess I overdid it somewhat and the lightest light ended up too bright by the 4th glaze, but in the latest glaze which you can see here I went over the whole portrait again with a darker glaze just to soften it a little. In areas where it was too dark again I just used a dry brush to pick off the paint and continue blending. I can always keep adjusting a portrait at a late stage if the client commissioning the portrait feels there is something that needs changing.
It is surprising just how close to the original grisaille the painting is, even when its possible to see how much refining and drawing has gone into the portrait over all the glazes. Its strange to see later very finished versions of a portrait where the grisaille is like a ghost, still very present but disguised under veils and glazes of colour. The grisaille functions like an anchor that holds the structure of the portrait in place, and many many changes can occur but the painting is still held firmly together by the initial drawing. Its the main reason I started learning how to paint using the grisaille method.
I always use the same mixes when I paint portraits using the grisaille method. All my glazes start with various quantities of the same colours: Alizarin Crimson, Cadmium Red, Raw Umber and Sap Green (a warm Sap Green). All the later glazes are mixed with these colours but with other additions, like Ultramarine Blue to cool it down, a bit of Titanium White to make a velatura or semi opaque glaze, some Cadmium Orange.. but always hovering around the same original mix. Of course this depends on the commission and the sitter having their portrait painted.

Here are a selection of photos showing the completed glazes done over the grisaille underpainting in this portrait commission.

This is the first stage, the grisaille. I will be posting a video of the first glaze in a few days. The sitter is the sister of the earlier portrait posted. I will be able to continue modelling the forms as I glaze. I have talked about this elsewhere but the drawing never stops while glazing is taking place, each glaze revealing new areas to develop in the painting. The grisaille is not perfectly formed but is enough to form an anchor for the rest of the painting. Hue or colour is in itself drawing and form and all the imperfections and flat areas are transformed with the glazes.
There are many different ways to make a grisaille underpainting; with black and white as here, or you can make a ‘verdaccio’ which is monotone green and white, or burnt umber and whites. In the future I would like to do some paintings with very limited palettes, like the Zorn palette which has Yellow Ochre, Black, red and white. Or like the one I used at school, Burnt Sienna, Cobalt Blue and White. Just thinking about it is so nostalgic and I fondly remember swimming in warm and cool tones back then.

I wanted to share the magical transformation an oil painting undergoes, glazing oil colour over a monotone underpainting.
I filmed myself painting the glaze and velatura over this portrait for one hour, in 3 short videos – this being the first. Its the first glaze and there will be a few others to finish the portrait, but this video shows the process, and I hope shows why I find it such a rewarding method to work with. It shows the dramatic results you can achieve in a relatively short amount of time.

This is Amy’s portrait, glazed in oil paints. I filmed myself doing this and it will shortly be on my youtube channel. Its still in the early stages, and when this layer is dry I’ll go over it again, up to 3 or 4 times. I don’t know if I’m going to film those other stages – they might be a bit boring as its just a lot of tinkering. In the early stages its quite dramatic how a few glazes of colour changes the grisaille into a very nearly finished portrait. Stay tuned!

When I began investigating Old Master techniques I had some brilliant instruction from James Scrase, a portrait painter who was trained by Pietro Annigoni (see his fantastic self portrait). He learned every traditional painting skill from Annigoni, including fresco painting, and he taught me to use Burnt Umber as a wash to draw the portrait first, and then build up layers of slightly opaque ‘half-pastes’ using colour and a little white. Also I was taught to add white with small amounts of blue and then glaze over it with flesh tones. This was one of my first attempts, of my cousin Jack. Of late I have been focussing on a strict grisaille underpainting but looking at this I think I prefer the slightly more fluid quality burnt umber can achieve with thinner washes.

Here is a recent portrait commission using the grisaille method, where the colour glazes overlap and create an optical effect as the light passes through each layer. This one has around 6-8 layers of oil glaze over the grey underpainting. As I have mentioned before, I use M. Graham’s walnut alkyd medium, which dries quickly enough and doesn’t give me a headache. I was constantly repainting and working into the drawing as I went, and the main problem in the end is the risk of over-working it, so at this stage I decided to call it a day.
The portrait has a rather serious quality that I like. There was a lot of revising and correcting, but the head looks as if it could be carved out of marble. As a sculptor by training I definitely enjoyed painting this head with its beautiful symmetry. It’s one of those things but I would rework it if I could get it back now, but actually I couldn’t because it lives in its own time and I correct it in further paintings. Each painting is part of a long chain of work that link one to the other, and each painting has its own quality, for better or worse. Actually I would have loved to carve a portrait sculpture based on this portrait.
There was a lot of correcting while painting the glazes, because the grisaille was probably not complete at the time of the first glaze. But as Philip Guston said, painting should have a moral aspect, and somehow all the effort spent in painting a picture or portrait is stored as a kind of moral force. The opposite would be something like doing it with a photoshop app and a click of a button. This is absolutely true and you can always sense this in a painting, and in the most subtle way all the effort, all the revisions and alterations, all the agony and effort, and joy, show in the final painting. Philip Guston was a true hero of art.

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.

For this portrait as usual I used a canvas on board, and cropped it slightly to fit the subject. I started with a grisaille underpainting using Raw Umber and Titanium White and a little medium. I’m hovering between a straightforward Ivory Black and White underpainting, and other versions, mainly Raw or Burnt Umber and White. Burnt umber has a little more warmth. I’ve looked around online and you can see people painting with blacks which are made up of reds mixed with greens, e.g. Alizarin Crimson and Viridan Green, or again different blues and browns. At school I was taught by my militant impressionist teacher Mr. Baines that using black was sinful and one should only EVER mix blacks optically, and his chosen mix was Burnt Sienna and Cobalt Blue. You can mix a nice black from these two, but I went off Burnt Sienna a while ago (I’m sure I’ll come back to it – at the moment it just has a bit too much character, like someone talking very loudly at a party, so you can here them wherever you’re standing!). I think you can achieve a deeper black mixed from Burnt Umber and Ultramarine or Cobalt Blue.
Having said all that, in the name of efficiency I have stripped back all of my processes to avoid unnecessary headaches so I generally I use Ivory Black and Titanium White! I have also learned from Louis Smith that a little Alizarin Crimson mixed in with Ivory Black gives it more depth, so I also do this on occasion.
The thing is that I can achieve this depth at a later stage by glazing darker colours over the underpainting so again the Alizarin Crimson gets ditched when I want to simplify the process. I’m possibly lazy, but if you are working on something over a few sessions and have to mix the colours each time inconsistencies can creep in and so thats just another layer of process that can be removed.
You can see an example of the depth achieved through glazing in the image below where the grisaille is actually quite bland in comparison. Dark glazes in and around the eyes give huge depth (generally I won’t use black at this stage and mainly use Alizarin and Sap Green or Cadmium Red and Viridian, or blues or browns or whatever..). This is the first glaze and already it has transformed the tonal range of the portrait.
