Last Lights on Tumut Valley


Step 1
This is one of the most recent paintings showing Tumut Valley in NSW. What attracted me to paint this scenery was the game of warm light and shadows through the whole view. The linen board was primed for oil painting and underpainted with a tint ultramarine blue and burnt umber.
Materials used:
  • 60 x 30cm linen board
  • Brushes: Long Flat brushes 12, 10, 8, 4, 2 liners (0, 00), Very long filberts (2, 6) (Art Spectrum Series 1100KLF)
  • Odourless mineral spirit +  Liquol (Art Spectrum)
  • Color palette: Titanium and zinc white, French Ultramarine Blue, permanent alizarin, viridian, sap green, burnt sienna, raw sienna, , raw umber, Flinders red violet, Australian red gold (Art Spectrum), Cobalt blue deep, yellow ochre (Norma Professional), Van Dyke brown, ultramarine rose, cadmium yellow light, medium, deep (Masterclass), cadmium orange (Old Holland) and lemon yellow (Michael Harding)
Under-painting (Blocking in)
I wanted to start off this painting over a very dark underpainting, so using a number 12 flat brush I blocked in the sky with a mixture of Flinders red violet and French ultramarine blue.
Cobalt blue was used to block in the background mountains, adding permanent alizarin and a touch of yellow ochre to the closer mountains.
The middle ground including trees was blocked in with a mixture of French ultramarine blue, permanent alizarin and yellow ochre. The foreground is the darkest part and so I used  a mix of French ultramarine blue and Van Dyke Brown for the ground and Van Dyke Brown with viridian for the trees.


Step 2
The next step was to start giving more form to the relatively abstract underpainting. Using number 10 and 8 flat brushes I started adding more clouds using titanium white mixed with touches of permanent alizarin, lemon yellow and yellow ochre. Dark areas in the clouds were darkened with ultramarine blue, alizarin and raw umber. I gave importance to create contrast between the darkest and brightest parts of the clouds using complementary colors. The distant sky was lightened up using a tint of cerulean blue with lemon yellow added to the left hand side of the painting, the side from where light is coming.
The mountains were given more shape by darkening the shadows. The highlights in shadows were painted using a tinted underpaint. The areas lit by the sun on the mountain were painted with a tint of lemon yellow and a touch of permanent alizarin + yellow ochre.


Finished painting

Mid- and fore-ground
A mixture of ultramaine blue and yellow ochre was used to paint most of the ground and trees in the middle-ground. The ground is darker and cooler (with the addition of more ultramarine blue) as you move to the right of the painting since light is coming from the left. Parts of the underpaint was not painted over to give the illusion of shadows, that at that time of the day are very long. The mixture was tinted slightly as one moves into distance. The areas that are hit directly by sunlight where highlighted with the addition of yellow ochre and some lemon yellow in the mid ground. The trees were painted with darker shade of the same color used for the ground.
For the foreground used the same base color of ultramarine blue and yellow ochre with the addition of a warmer yellow for the highlights. I used different mixtures cadmium yellow deep, medium and light or/and Australian red gold with sap green, sap green and burnt sienna or permanent alizarin. The details were added gradually over a number of days, thus allowing the previous layer to dry. For most of my painting I used liquol which dries very quickly but for the final highlights and details, paints were used without the addition of any medium. During each session I continued to enforce the dark shadows and adjusting the saturation, hues and values of the highlights.

Fingal Bay - the finished painting



Fingal Bay - NSW

In my last post I showed how I did the underpainting of this artwork using acrylics, on location. Using acrylics while on location has its own advantages and disadvantages. An advantage is that you can easily carry the painting with you while travelling because it dries quickly and so you can place it anywhere you like. On the other hand, if working in very warm conditions, excessive fast drying can be a disadvantage during the painting process itself.

So back to the studio I decided to finish this painting in oils. You can always work with oils over acrylics but not the other way round. I started from the sky, using cerulean blue and white with a  touch of alizarin crimson and raw sienna to the distant sky. I darkened the sky as I moved forward adding cobalt blue and alizarin to the right hand side corner and white and a touch of viridian to the left hand side corner from where the light is coming.

The distant land on the left was blocked with cerulean blue and highlights with raw sienna and white. The middle ground was blocked with cobalt and alizarin while the closest and mass on the right was blocked with ultramarine blue and alizarin with touch of yellow ochre to gray it. 

For the distant water I used ultramarine and phthalo blue and phthalo green, adding yellow and Australian red gold to the shallow water on the front. The detailes of the tress where painted using ultramarine blue mixed with yellow and a mixture of burnt sienna, viridian and Australian red gold. I added two sailing boats to the distance to cut the horizontal shoreline of Sharks Island in the distance. The wet sand on the fron was painted with yellow ochre mixed with burnt sienna and cerulean blue.

How to make your own glass palette

Glass palette



During the last couple of years I tried several different kinds of palettes that are available on the markets starting from the traditional wooden ones to the most recent disposable ones. Depending on the situation and where I am painting all types of palettes have their own pros and cons. For example I find disposable palettes convenient because I do not need to clean my palette afterwards, but they are very inconvenient if I am painting in the wind. When I do not have a lot of space where to work and put things around me I usually use a big piece of perspex which fits exactly into my French easel and so I can leave the colors on it ready for the next session or even put in the freezer to be used couple of days after.

Recently I decided to start using a glass palette, that is big in size and that I can take with me when I go to workshops and painting outside. The size of the palette is approximately 55 x 35cm and it is simply made up of a piece of normal glass painting at the back in grey with acrylics. The grey color helps you to see the colors much better since it reduces reflections. From the local store I bought the wood and piano hinges I required to build the wooden case myself. I then fitted this piece of glass into a home-made wooden box which I can close and lock when it is not in use and during transport. When open I can place the whole box on the drawer of my French easel. The open lids serve as small side tables on which I can place my colors, mixing media and brushes. I also fitted a wooden brush holder on the side.

When ready I simply transfer all the brushes into my French easel, place colors in their box and clean the mixing surface with a clean tissue or cloth. Being made up of glass makes it very easy to clean. The advantage of a big palette is a larger mixing area as well as enough space to place your colors around. I always place my colors in the same order as they are on the color wheel, that is reds on my left, blues on my right and yellows in front of me.

For more information about this easel please do not hesitate to ask or contact me.

Painting with acrylics and oils

Today I am writing about a recent painting I finished of another Australian landscape.

I started this painting from the above reference photo, which I took while vacationing at snowy mountains very close to Thredbo, almost two years ago. This photo has very nice background mountains but the foreground is not that inspiring. However I decided to keep the basic shapes while modifying the colour scheme and adding gum trees to the foreground. Using charcoal I did a rough sketch of the main forms to define the background, middle and foreground. I added a farmhouse at the far end of the middle ground.


I started the painting by executing an underpainting with acrylic colours to establish the basic forms as well as the mood of the painting.


I decided to paint an early morning scene and so I chose a pallette of warm oranges and yellows and cool blues for the background. I then removing some trees and the road that was originally winding uphill in distance. The advantage of using an acrylic underpainting is that it dries very quickly although you can achieve the same result if you had to dilute oils with mineral spirit.

Next step was to go for a layer of oil colour to enforce the shadows and mid-tones in the painting. Colours used were titanium/zinc white, cobalt blue, ultramarine blue, alizarin crimson, cerulean blue, yellow ochre, cad orange, burnt sienna, Australian red gold, virmillion, burnt umber, sap green, viridian,cad yellow light.





The final stage was to add the details and highlights, using both brushes and pallette knives. The final product can be seen above.

Painting Tools & Equipment

Canvas

You can paint on any type of surface as support such as paper, wood panels, metal etc. For oil painting the most commonly used is canvas, either stretched or unstretched. You can buy canvas either in roll or ready stretched, however buying a roll will turn out to be a cheaper alternative. You can buy this canvas either already primed or unprimed. The primer acts as a base for the oil (or acrylic) paint to adhere to without cracking, peeling, wrinkling or shrinking. The most commonly used primer is gesso and it can be applied either as a single layer or double layer.

There are different types of canvas of which cotton is the most commonly used. The other type is linen that is very expensive. It is important to use good quality canvas and this usually has to be of a minimum of 10 oz and 12 oz for bigger paintings. Ready made canvases found in stores are barely 8 oz and even less. If you buy canvas by roll you can have a better quality canvas with the same price that you buy a similar size but of an inferior one from a store. 

Brushes, Knives and Palettes

For oil and acrylic painting it is very important that you buy good quality brushes. Inferior brushes will start losing hair while painting and it is really annoying to stop every minute to remove hair from the surface of your painting. Do not buy synthetic ones but only buy those having natural hair such as hogs hair. Brushes come in various shapes and sizes. You must have a selection of round, flat, filbert, fan and liners (for fine and delicate work). You must also have a selection of sizes usually numbered from 0 to 12 (12 being the largest). Different brushes are used for various techniques. A good brush must maintain its shape when being used. You must also have a 2 inches brush for background colouring (and underpainting), that you can buy from an ironmonger (also used for house painting). The most important is to clean the brushes while using them and after you finish as if you do not do so then you will end up wasting money. While painting you have to clean the brush before picking up colour and this is done using tissues. Do not clean the brush with turpentine while painting unless you are going to go from a dark colour to a lighter colour. When you finish first remove excess colours using a tissue and then clean the brush in mineral solvent followed by rinsing it in water with a dishwashing detergent. Do not throw away old brushes as you might find them useful to create different effects.
Painting knives are used to mix paints on the palette as well as to paint, usually very useful to lay thick layers of paint onto the canvas and to create structures like tree trunks and rocks. You can also use them to create fine but straight lines, snowy mountain peaks or to create small waves or ripples on a water surface. Same as brushes, painting knives come in different sizes and shapes. Always clean your knife before picking up colour from the palette.

Use a flat palette for oils and acrylics as it will be very difficult to pick up paint from palettes used for watercolour. You can have a wooden or a perspex palette, or even simply a disposable plate. Alternatively you can use a tear off palette, which is very useful and you do not need to clean it afterwards.

Paints and diluents

Always use artist quality paints for both oils and acrylics. Artist quality paints have more pigments rather then binders. Artist quality paints do not fade away when mixing and also they will last longer. Artist quality oil and acrylics are usually heavy bodied and thus easier to paint using painting knives.
When painting with acrylics, paints are usually diluted to a creamy consistency with water. To increase drying time you can use one of the many retarders that are commercially available.
Turpentine is usually used to dilute oil paints for underpainting to decrease drying time. Try to use odour free turpentine especially when working indoors. Oil colours can be diluted with linseed oil for upper layers of a painting, thus increasing drying time. Poppy oil is another diluent that can be used to dilute oil paints. The more oil you add the more you increase the drying time. The consistency of the paint should be creamy and should be in a way that the paint is easily released from the brush onto the previous layer. Liquin is another excellent medium that decrease the drying time of oils and is very good for glazes.

Varnishes

Varnishes are used to protect the painting and colours from deteriorating with time besides making it easier to clean. There are two types, matt and gloss. Matt varnish do not reflect light and hence will give a uniformity to the painting, since oil paints have different glare when dry.
Allow the painting to dry well ideally about 6 months. You can apply varnish either using a brush or using aerosol spray. To apply the varnish lay the painting horizontal on a clean surface (dust free) and apply onto the surface in a uniform manner. Apply in a well ventilated place or outside, and beware of any flying insects that can rest on it accidentally. Matt varnish can sometimes form a cloudy appearance after drying sometimes affected by humidity.
