Painting the Traditional Way

Final Glazing


After painting the background surrounding the figure, it was time to begin the final glazing stages on the painting.

This is the final part of this blog on painting a Woman in a Tropical Pool. Finishing a painting usually takes longer than I expect. Due to my OCD nature, I spend a lot of time tweaking until I feel that it’s right. Mostly the process consists of lots of scumbling and glazing.

As you can see in the picture above, I added colour to the philodendron leaves with semi transparent layers of sap green, cadmium lemon yellow, cadmium green light and titanium white. You are still able to see some of the warm browns underneath the green from the underpainting.

I also gently scumbled a layer of  cool transparent white in parts of the background to make it recede and create spacial depth.

What is scumbling and glazing?

Both scumbling and glazing are two techniques where the paint is applied thinly enough so that the proceeding layer of dried paint is able to show through. They are most commonly used when oil painting, but scumbling is also particularly useful with acrylics, and glazing with egg tempera.


Beautiful and luminous effects are achieved when applying glazes. A thin transparent layer of paint, usually made slightly more ‘wet’ with the addition of more oil or medium, is applied to the dried painting underneath.

It is a wet over dry technique, and it’s important to make sure your painting underneath is absolutely dry before you start glazing. Otherwise it will become a total mess.

The effect is that light travels through the transparent layers of paint, is reflected off the lower paint films, refracted through again and creates a glow.

Glazes are usually added at the last painting stages over the opaque painting layer. By adding more oil-rich glazes near the last stages, the ‘fat over lean’ rule is maintained.

Glazing is generally a darker transparent colour over a lighter colour and is therefore perfect for creating shadows.


Scumbling is similar to dry brushing, where you brush your paint thinly over a dried paint film. Usually it is the opposite of glazing because you use a lighter, more opaque pigment over a darker surface. And usually no medium or oil is needed because the action of brushing it out thinly, disperses the paint enough so that it appears semi transparent.

Because of the vigourous scrubbing action of brushing it out, it’s important to make sure the proceeding layer of paint is absolutely dry. Also, I use old messed up brushes for this technique.

It is a dry on dry technique and the secret is to use very little paint and to brush it out thinly, so that the painting beneath can still be seen.

It’s great for softening edges, creating atmospheric effects like clouds or spacial depth. Having scumbled in the ‘dead layer’ from the previous post over the woman’s body, you are still able to partially see the anatomical structure of the underdrawing.

Scumbling a lighter, slightly opaque pigment on top of a darker area of the painting, will bring out a cooler tone in that base colour.

The prismatic effects of painting in layers of glazing and scumbling can only be achieved in this and no other way, because of the physical properties of light being refracted through the different layers of pigments.

The effect of painting in layers (indirect painting) with glazing and scumbling and other techniques, creates a painting that is usually more subtle and complex in tones and hues than the direct painting style.

Direct painting, also called alla prima painting (Italian for ‘at the first’) is where the painting is created in one sitting, without allowing layers to dry in between, and usually is purely opaque. Usually the direct style is much looser and may be a technically vigorous with bold brushstrokes, less refined detail, and more ‘flair’. But it lacks the glowing luminance of glazing in layers.

Quick history lesson

Before the invention of oil painting by the Flemish artists Jan and Hubert Van Eyck in the 1400’s, the popular painting medium of the time was egg tempera.

This delicate and precise painting method involved many thin transparent glazes of colour on top of each other until the desired chroma and saturation was achieved.

The Flemish oil painting tradition continued with the glazing practices of tempera painting, applying transparent or semi-transparent glazes on top of opaque underpaintings on wooden panels. Oil dries more slowly and evenly than tempera, which allowed the artists more freedom with reworking their underpaintings and loosening up their style.

The invention of oil painting also allowed greater pigment strength and therefore greater luminousity, higher chroma and saturation.

When oil painting found its way to Italy, the Venetians in the early Renaissance developed it further by painting on canvas instead of panels. They painted their underpaintings in grisaille (grey monochrome) or verdaccio (greenish-grey), then pushed oil painting further than before by applying techniques such as glazing, scumbling, sfumato (lost edges), frottage (dry brushing) and impasto (thick textured paint).

The final painting stages

In the final stages, I did a lot of back and forth painting of the woman that wasn’t strictly linear. I worked more on the background, the birds, the waterfall and the surrounding water at the same time as working on the woman’s body.

I added shadows and coloured glazes and built up interesting effects of colour over several months of painting.

Using the verdaccio technique a bit differently

Usually the verdaccio is a traditional Venetian technique which is done in the beginning stages of the painting as part of the initial underpainting. But I decided in this case to apply it nearer to the end.


Painting verdaccio on face
I decided to add a verdaccio layer for more complex colour effects and add coolness to certain areas of her skin.


Painting the woman, I decided to glaze a greenish blue verdaccio in the shadows of her body on top of the dead layer. This would create more interesting colour effects for the glazes and scumbling I had in mind to come, as well as tie in the colour harmonies of the shadows and the surrounding cool green/blue environment the woman was immersed in.

I used a mixture of ultramarine blue, burnt sienna, transparent gold ochre, raw umber and terre verte for this.

I worked on little details like glazing colours over her face and ear. You can see how it’s starting to look transparent in some areas and more opaque in others.

Over this dried verdaccio layer, I scumbled in the warm lightness of her skin with titanium white, gold ochre and permanent rose.

After that came many layers of transparent glazes for shadow areas and reflections, and scumbled opaque highlights. This is when I’m painting mostly by instinct and taking my time, not thinking of any steps or formulas. The painting starts coming alive.

The hair, for example, required many glazes of colour, getting darker with each layer.

Just spend time looking at your painting

Sometimes I don’t work on the painting for weeks. Besides letting the layers dry better, it’s also good to give your eyes a break. And then stand back and study your work.

As the painting neared completion, I kept checking it in the mirror. This helps to give your brain a fresh way of seeing. I check the proportions, the spacial dimensions, the colour harmonies etc. I also squint my eyes a lot to check the values and contrast.

As I’m glazing and scumbling over the flesh of the figure, adding ripples and reflections to the water and adding transparent shadows to the leaves, the parrots and the rest of the painting, I am constantly checking colour temperature, depth of saturation and harmony. I work across the painting as a whole so that nothing feels separated or jarring to the senses, like it doesn’t belong in the painting.

The completed painting

Finally after all the work, it’s a satisfying moment to apply the last stroke, stand back and pronounce a finished painting.

I always try photographed my paintings as carefully as possible. Using polarized lights and filters to prevent glare, I photograph at night in my studio.

This painting was now ready for postage to Australia. So I removed it from the stretcher, rolled it up and packaged it.

The painting arrived safely in Australia to its happy new owner and I was very glad that it didn’t get damaged or lost.
